From the pictures in this video I think that I do have yellow algae. I've been fighting it for the last few weeks thinking that it was pollen from all the trees and plants in the area. It is a mustard yellow "sediment" that I keep vacuuming to waste and also a yellow deposit on the sides of my above ground pool and the wet portion of the ladder/stairs leading out of the pool. I'll try this process and report back how it goes for me.
Hi thanks for your videos! I did the triple shock you mentioned in your video but I added the shock directly to the pool, without dissolving it before. Is this a big deal? How long can I swim again after? The next morning the water is very opaque, not clear.
Yellow mustard algae and I have a long relationship. I've battled with it for a few years now. I live in the New England and the stuff loves my pool. This video is very helpful and thank you. It's been 24 hours and I see a difference, but not there, yet. One comment: I rinsed out the sand filter using my garden hose for about a half hour. (Instead of backwashing) The garbage that ran out was opaque-nasty. Next time I'll backwash after rinsing out the sand to be more thorough. Overall, I'm seeing results, so a big THANK YOU.
So you have rinsed your sand with a hose?! We have just back washed! My husband thinks we should change the sand before next year because we have taken a green pool to blue and cleaned ALOT out and put the sand under stress.
How do you know if you have it? I shocked the pool with algicide about a week ago because it was pretty foggy and now I seem to have this fine dust on the floor (but no longer foggy) that's not easy to vacume up. Gets a bit spotty too. It easily forms a cloud when pushing the brush over it.
Thanks for this. I, too, was confused, I have always understood that chlorine is bleach and yet he says that mustard algae is bleach resistant? What is the point in wiping and washing everything with bleach?
It doesn’t make sense to me either. And then trying to keep chlorine ppm up for days on end when sunlight is burning off 1ppm/hour? Use a good algaecide, it worked for me. Some of these “pool guys” act like the only two chemicals known to man are chlorine and acid. Even when something is chlorine-resistant 🙄
I had my pool chlorine up to 10 ppm, Ph was normal, etc. And the mustard algae persisted. Then, I used an algacide and it worked great. Even at low chlorine levels. Only cost about $40 for the whole summer. I also put my pool toys, equipment, bathing suits, etc. In the treated water so I wouldn't reintroduce the algea. This is in Northern Illinois.
I’ve had this same issue. Yellow algae and the pool supply store kept saying to shock it. Well turns out yellow algae is resistant to chlorine! You need an algacide to get rid of it. I used yellow treat.
@@mikebell7394I use a commercial product by EZ-Chlor but if you do get a algaecide without copper so you don’t accidentally raise your copper levels depending on where you live and what’s in your water
I wasn’t sure if it was yellow algae or just dirt and debris that started after a chilly week of no swimming or using the pool. But it was yellow. Although as I’d vacuum, it’d look more brown. It didn’t climb up the sides of the pool, but kept spreading on the bottom. After vacuuming and shocking it was extremely cloudy. A few days later it was less cloudy, but still too cloudy (white, foggy cloudy) to want to swim in it. Between that and cool weather it was still not being used for a few weeks. It then got yellow all over the bottom of the pool again. It’s a small above ground pool, a little over 4000 gallons. I’m recovering from chemo and dealing with lymphedema so it took me four days to vacuum it again. I just shocked it last night. It’s super cloudy again. The new filter was green after all the vacuuming, so it got rinsed out. I’m not sure whether to shock it again and then a day or two later add clarifier? After not the best swimming weather in August, it looks like it’s going to get hot and humid again in a few days - perfect swimming weather,. But I’m feeling stressed that the pool might not be swimmable in time if I can’t clear up the water. Swimming has been a huge help physically for me. Not to mention fun, which I definitely could use this year. I can’t reach under the steps though to vacuum or brush. But yet it still had stayed clean as far as no yellow or dirt on the bottom for over a week or two. But then we got some more not so great weather, and I’m not able to constantly vacuum, and the slight cloudiness got worse again and more yellow on bottom. There were some leaves and tons of tiny dead bugs this last time I vacuumed the past few days. Lots of that sort of stuff in the water. Last year was so easy to maintain, no problems at all, although I had help, and it was being used constantly, and the weather was better. Not sure what to do next to get it swimmable within the next few days, if that’s possible. I would absolutely love even just a few more days of swimming before the summer is totally gone for the year. Any suggestions?
My pool is balanced with the chlorine on the high end. I am brushing my pool twice a day and cant keep up. When I brush I make a yellowish cloud. My pool is 18x36 vinyl and I am Upstate NY. the water is clear enough to see the bottom of the 4' end but cloudy at the 9' end. Is this Mustard algae?
Hi there! Im in the process of doing your triple shock method, curious, I have an above ground pool and the filter/pump doesn't have a "waste" function. Suggestions? Thanks!
He said to get a pool brush for your type of pool to brush it off first. Then adjust the pool filter to whatever setting he said to get it out of the pool. The rest is to clean the residue out.
Do you vacuum the pool to waste the morning after the first triple shock treatment or do you brush again if you still see it & triple shock it again until it’s gone?
Two questions - No mention of mustard algaecide. When do I use it? Also, I have a cartridge filter - it's colored mustard yellow! wont hose off. what do I do?
Thank You! This really works! I tried a lot of products and liquid chlorine, did not work. Did what is described in this video and bye bye Mustard Algae! I don't ever leave comments but this one is well deserved!
I hate my pool that I put in 32 years ago. I take care of the pool myself and have been fighting mustard algae for the past 2 years. My plaster is 11 years old, is it still OK to use a metal algae brush on it? I bought one then I was afraid to use it so I returned it. I live in Phoenix and have lots of trees.
How does the algae stick to surfaces? You talk about brushing the algae. I tried brushing, but nothing comes up. I put in 7 bags of shock one day, and although it looked a little better for a day, the liner was still stained. (15,000 gallon, 24' round). These stains were not there last year. I could not even brush it up with my hand. It is not slippery at all. Could this be something else? thanks!
I have an above ground pool intex 12x30 I drained it. Can I just clean the liner and all other items with Clorox bleach and it solve the problem or do I still need to refill and shock it to kill the Mustard Algae?
This stained my pool liner,and it doesn't wipe off. Its very clean in parts of the pool then big patches of brown stains . This stain is now part of my liner. You cant feel it at all
Not sure if I have this mustard algae or not. The substance I have is not slimy, it’s a brown gritty powder on the bottom of my in ground pool. I vacuum it clean and then turn off the pump/filter overnight, wake up the next morning and it’s back all on the bottom of my pool. Also, we have a sand filter. What could this be from?
Great video Love watching your videos I’ve done what you said but it looks like a huge stain Had it before and did what you said and it helped Now ? Maybe needs resurfacing ?
ok, love ur vids, but what do i do if i have an above ground pool with a bestway/intex? cartridge filter? 10,000 litre pool (not sure of gallons atm) and the filter pumps almost all of that in one hour, so it’s a good one. i can’t filter to waste though! do u have any tips for this kind of setup? i also just fitted a salt water chlorinator and have a tonne of mucous blocking up the filter. chem levels are fine. flow and chlorination are good according to the new system. please can u help? we’ve already had a couple of weeks of 38 deg celsius and it’s not even summer. i just wanna use my pool and enjoy all the money i’ve spent on it lol
You're an amazing resource and person! Thank you for all the help. I recently started taking care of my pool. I always had a pool person, but my guy stopped serving my area. He was so good at what he did - a tad expensive, but because our pool was always so well maintained, we didn't mind. We hired someone new and within 3 months there are pool stains, algae, etc. The guy wanted to charge a small fortune to fix the issues. I fired him and just started figuring it out on my own. I still might hire a pool service in the future (it is a LOT of work), but I feel great I have my pool chemicals, DE filter, etc. in great shape all because of you and some helpful knowledge from local pool company, but mostly YOU!
When I brush the mustard algae it just clouds all over. When I vaccum it same thing. My alkaline and PH are perfect and my chlorine is extremely high and I can't get rid of it. Please help!
Let the algae settle to the bottom. So pump should be off for 24 hours then shop vac it off the bottom very carefully. Took me forever to get rid of it but I finally figured it out.
We have Mustard algae. We have been fighting getting our pool clear all summer and finally found out why. So my question is our pool is relatively small it’s an 18ft above ground pool. Would it be better to just drain the pool and disinfect it and clean it and start over?
His shock method worked for me, but it was ALOT of shock. I've got in an in-ground 25k gallon pool and this crap has been driving me crazy for a month. I got a little pool from walmart and put two lbs of shock to soak all the pool equipment in also. Make sure you get everything that has been in the pool sterilized of that yellow crap. Goodluck
What do we do if we have about 2ft of water at the bottom of our 16x30ft above ground pool, and it very clearly has mustard algae in it? We didn’t have our filter or anything plugged in yet because we are just at the beginning of the swimming season.
I have SO much liquid chlorine I don't want to buy several bags of Cal-Hypo to do this so can you just tell me what PPM of chlorine I need to maintain instead?
Fantastic video! keep it up, some vids are sooo boring to watch and enjoyed yours. I have a 10x24 Intex pool, and mustard algae. I believe I have conquered the worst as my pool is crystal clear today. BUT!I have it floating on the surface maybe do to put algeacide into it? I have been skimming it off but it spreads as I do this. What else should I do. Thanks.
Before finally coming to the realization that I have mustard algae, I have been aggressively shocking my pool with liquid chlorine AKA sodium hypochlorite. With the high levels I have now should I still do as you say and shock the pool with calcium hypochlorite as the video suggests
All the steps are the same, just use either dichlor shock or liquid chlorine shock (not cal-hypo shock: that can create calcium build up in your salt water cell). You can even try running the "superchlorinate" mode on your salt system to see if that helps.
I brushed my 5500 gallon pool and added almost an entire gallon of liquid chlorine, but the mustard algae was already settled to the bottom again and this morning it’s all still there PLUS some. What do I do?! 😭😭😭
My pool is cloudy but I can barely see the bottom of my above ground 18' round. Is that mustard algae or green algae? I've heard, mustard algae does not cloudy up. My pool is balanced and my chlorine is 20 ppm, but still cloudy.
You probably have microscopic debri to get rid of it just add a chemical called floculant it will sink all the microscopic particles to the floor then just vacuum it out to waste or you probably have poor circulation!
We just realized what we have is yellow algae. *#*% we have been shocking and putting in liquid chlorine and vacuuming to waste and brushing for weeks!! But this stuff still comes back and settles on the bottom! I just saw some videos that it is on all our stuff. Great. First of all is it hazardous to a person when they get in the pool to vacuum and brush? Ok so after I wash down everything Do you recommend I put in Yellow Out? Or other algaecide? We are basically just trying to clear/clean the pool to get it ready to winterize it. Help!
So I have a 30,000 gallon pool and want to do the triple shock method. I need to make sure I’m understanding this all the way. Am I using liquid chlorine or the bags of powdered shock? Please let me know how many of gallons because I do know that if its bags of shock I would use 9 bags. Right?
I have a serious yellow algae problem in my intex 15x33 pool. Not 1 single vacuum has picked up the algae 😩 it just blows it all around. I don’t know what to do to get it OUT! Help!
@@bkmagic1349 I meant, adjustments to chlorine levels based on your CYA. I also drained pool to correct CYA it is at 50 now. I ended up using bio-dex knock out yellow and it worked great. The bromine in it did what the chlorine couldn’t. Ended up a little cheaper than triple shocking as I only had to shock once with knock out and then shocked again the next day.
@@johnedwardii nah..CYA just protects chlorine from the sun..as long as ur CYA is 30-50ppm....ur good..u don't gotta have chlorine at 5ppm if ur cya is 30ppm as an example
I have a 14,000 kidney shaped marcite pool in Florida. I have to brush it at least once a week to keep the algae away. It’s relatively uniform, not splotchy, and grows on the floor and walls of the pool. It’s yellow in color. Is it mustard algae or something else?
Didn't work. However Stop Yellow killed it in it's tracks. Disclaimer, we've been having a lot of rain here in north-east Florida and anything on the pool screen gets rinsed into the pool.
I’ve had good results using di ammonium sulfate for mustard algae. Follow the treatment with 2 pounds of stabilized chlorine granular per 15 k of water. The product I used (green to clean) recommended an elevated ph of 7.8+.
I get the gloves mask and goggles for the video lol but do you really where all that in the heat while cleaning or clearing algae? Still love the videos
You make great videos. I am In N. Alabama 95 and. humid. After watching your video I think I have brown rather than mustard algae. Salt water pool and chemistry is correct except I am 3 bags of salt low. 2190. I have vacuumed to waste for 3 days but every morning there is a slight brown layer on the bottom. I am going to triple shock it tonight thanks to your info. 18000 gal x 6 lbs of shock. Thanks again!
When you say vaccum to backflush. I know some valves have 3 ports, 1 called waste. My filter is pac-fab (old) it has re-circulate or backflush. So do I move it to backflush to vaccum? Seems like my 20,000 gal. pool gonna be half empty before I finish. And do I clean the grids and add DE before or after vacuuming?
I believe mustard algae is my friends’ problem. South Houston, sand filter. All summer we vacuum to backwash Butt, it’s back quickly and runs Kreepy Krauly as usual. I am certain the sand filter needs to be addressed. I did get him to follow your steps once. (once, not all Three treatments) Questions: any special instructions for filter? If you’re instructions are followed will filter be clean?
New owner of a house with a pool. We have a pebbletec pool so I really can't tell if the debris in the bottom of the pool is dirt or algae. It clouds up when you brush and will make the pool super cloudy until it settles again. I have a Hayward 4 cartridge filter, with no way to bypass the filter to waste. I do have drain plug on the filter. I have read that i should not manually vacuum through the filter. Whats your best solution and what's the best way to figure out if this is dirt or actual mustard algae. As of this morning, The pool is balanced.
I’m sure you’ve figured out by now but touch with your finger and see if you can lightly “push” it.. if it goes up in a small plume and doesn’t settle immediately, it’s most likely algae and not sand.
Ive got it in a new pool (been up for a year) but nobody has been in it at all yet. everytime i think its gone it comes right back within a couple days. ....im stumped.
First of all i suggest against above ground pools running salt chlorinators because of rust issues. Second salt pools are chlorine pools. The salt ionier uses salt in the water to produce chlorine. The short answer yes, it will work.
What is a clear algae, looks like clear slim floating in the water. My wife gets it with a leaf skimmer with a fine mesh. I think we got it. Saw it last summer when we were into swimming about a month. What is this jelly looking stuff ?
Husband went to close.pool. brushed n shocked n then back washed. Bunch of yellow he says in the sand filter. Meanwhile he lowered the water n ik expecting so cant even shock it now. Help!? Its cold enough to close so it shouldnt grow until spring but wht can I do? Add bleach straight to the sand filter?
I have a salt water pool that gets a lot of sun. I get mustard algae on a weekly basis, sometimes every couple of days. I’ve tried a lot of algicides that are specifically for mustard algae. Nothing seems to work. What should I set my salt chlorinator to if I’m going to try this method you mentioned?
Got it here in Massachusetts, second summer owning a pool. I think I got it from my plastic ladder that I dropped in. It was laying in my lawn all winter. No idea. Time to buy some bleach!
I just installed the PoolRX into the skimmer (from your site). Within 24 hrs, I'm seeing this. Thought it was sand from the sand filter but it's not grainy. I thought going to a mineral system was supposed to prevent this ("eliminates all algae")??
Thanks for your video. I have a problem with mustard algae. I did your process and it didn’t go away. Tried 6lbs of shock the second time. Seemed to go away for a week and now it’s back. I have done everything. Not sure why it keeps coming back. Will flocking help?
I am in Arizona and just had a run-in with the mustard and I use liquidated chlorine shock instead of what they recommended. I added 1 gallon for my 6600 gallon pool. worked like a champ. putting chlorine puck in my skimmer to keep chlorine levels slightly elevated and evenly dispersed in the pool.
I fight this stuff every year, but my pool is out in the middle of a conservation area right smack between 3 ponds. Evidently it’s commonly found naturally on trees around ponds. I highly recommend following these guys instructions as they have worked for me and balancing that ph and getting the right amount of chlorine seems to be key. Also you’ve gotta be prepared to waste the hell out of the water to flush it out of the system and get it out of the pool. I’m hooked directly to a well with the pool, but if you’re in town that’s gotta suck. I’ve heard there are methods at filtering it out of the water but only directly flushing it out has ever worked for me. Goodluck to anyone else fighting this crap
So I just did the shock the sh&$ treatment overnight brushed it again this morning because there is still algae on the walls. Mostly in the deep end. And now in looking at it again it appears green to me. Help! Can’t scrub hard enough to get it off the walls.
8 week old pool plaster. Tahoe Blue Diamond Bright. I'm dealing with 1 week plus now possible yellow algae or metal stain. Pool was 99% covered equally with a yellowish/light brown somewhat slick substance. I'm in Houston. Had major landscaping jobs with lots of fertilizer AROUND the pool done, but was careful to remove debris immediately. Some leaves, branches, mulch fell in pool but I was right there with the skimmer to clean it up to ensure it didn't stay. Organic matter was a concern when we moved in (two months ago as well) so we removed most of our trees and bushes in the back near the pool other than a large Magnolia tree which is next to go because it sheds too much. One day the pool was blue, literally the next it was covered. I was treating a brown spot from tree dropping with a little acid and noticed it was bright blue. Compared to the rest of the pool I realized that I had a problem. First test showed 8.0 PH and low chlorine. Starting lowering the PH with 3 gallons of acid and the material washed off immediately on the steps and areas I poured it into, however everywhere else was really unaffected. Seems like it all happened after the landscaping jobs, fertilizer, mulch was all done-despite ensuring nothing was getting in the pool. Perhaps the rain washed fertilizer into pool and caused a metal reaction? I used Ironite on the plants which obviously could stain but was careful not to get anything in the pool. Chemicals were checked weekly perhaps a little less than they should have been admittedly. Chlorine a little low. Phosphates were 1,500! Two different pool stores testing my water said to get rid of phosphates, quadruple shock, algae feeds on phosphates, etc etc. Pour the chlorine in-gets a little cloudy brushing even with wire brush doesn't do much. I have triple shocked the pool 2-3 times in this time, running a perfect PH and got phosphates down to zero. After a few days got water perfect. Pool plaster company is blaming chemicals and that it's absolutely yellow algae. I hired another pool company to come out and they tested, felt, brushed and looked at the substance and said it was not algae. Especially after the high chlorine and shocking. Pool stores testing water gave me yellow out-and it immediately got rid of whatever it contacted, but those are very small bottles. Pool stores are saying it's not algae, that it's stain from the phosphates. My metals were little high one day, but nothing crazy. Been testing water every day. So far the only thing that lifts the stains is yellow out or acid, but just in small areas. Was told that I should drain and acid wash the pool. I have a 16,000 gallon pool. Changed filters and there were huge clumps of green smooth and slimy matter all over the filters and chunks in between no doubt slowing the flow. After the change pool seems to be getting a LITTLE better but not as fast as I'd like. Pool plaster company wants me to dump hundreds more of chemicals and snake oil into the pool... pool stores laughing all the way to the bank and my arms/back are sore from scrubbing. How long should this stain persist? And how do I know what the heck it actually is??? I've got about $600 in a little over a week in chemicals and filters and dozens of hours brushing and still about 75% of my pool is still covered. Only the steps are starting to show the beautiful Tahoe Blue new plaster color I was seeing a little more than a week ago. Please help! Thank you!
I treat with yellow out add a jug of Chlorine and the same time. Then follow up the next day with another jug of chlorine. COMES BACK IN ABOUT A WEEK :( what do I need to do????
Is mustard algae gritty? I have brushed and brushed and it's not coming up...I have spent hundreds of dollars!! Every time I go to the pool store he tells me to get something different!!! Help!!!
We have mustard algae only on our sun deck area. No visible algae in other parts of the pool. We have brushed and treated according to our pool service repeatedly. Brushed, treated and shocked. Still settling on sun deck. Is there something else other than tutorial advice we should do?
not sure what i have , looks like yellow mustard, but stuck to liner in the whole shallow end wont come off, tried everything pool is only 7 years old? been shocking quad amounts, brushing , will not come off liner, inground pool , any suggestions anyone? thanks
Can I just sink all my pool toys in the pool to disinfect them? I feel like that would be easier and more effective than trying to wipe down every nook and cranny.
I have spots of an odd, very light colored substance on the bottom of my 6,000 gallon vinyl pool that kind of looks like sand. The water is crystal clear and balance (because of your videos) It doesn't stick to anything and turns to "dust" when I even touch it with my pool brush. Do you think this may be yellow algae?

You could vacuum through the filter but with the drain valve open.
What do you do if you have an Intex style pool with a cartridge filter and no way to vacuum to waste? 😭
Is it best to brush the pool before shocking it so its all stirred up?
How do I know it's dead? Will the residue on the bottom go away on it's own? Or is a vaccum the only way i can do it?
He said to get a pool brush for your type of pool to brush it off first. Then adjust the pool filter to whatever setting he said to get it out of the pool. The rest is to clean the residue out.
Do you vacuum the pool to waste the morning after the first triple shock treatment or do you brush again if you still see it & triple shock it again until it’s gone?
I'd sure like an answer to your question as I've wondered the same thing.
Do i run my pump like normal or put it on circulate?
If I have a dolfin do I need to take it out the pool and clean it?
What if I have salt water pool .. which shock should I use ?
So after getting rid of it do I use algaecide every week to prevent it from coming back?
Two questions - No mention of mustard algaecide. When do I use it? Also, I have a cartridge filter - it's colored mustard yellow! wont hose off. what do I do?

Glad it helped!
You either didn't use enough or your chorine was garbage! always works for me, but you must super shock ir!
So when I run pump, should it be on recirculating?
I hate my pool that I put in 32 years ago. I take care of the pool myself and have been fighting mustard algae for the past 2 years. My plaster is 11 years old, is it still OK to use a metal algae brush on it? I bought one then I was afraid to use it so I returned it. I live in Phoenix and have lots of trees.
How does the algae stick to surfaces? You talk about brushing the algae. I tried brushing, but nothing comes up. I put in 7 bags of shock one day, and although it looked a little better for a day, the liner was still stained. (15,000 gallon, 24' round). These stains were not there last year. I could not even brush it up with my hand. It is not slippery at all. Could this be something else? thanks!
Did you get it resolved?
Do you vacum first? Then add shock? Or does it matter?
I have an above ground pool intex 12x30 I drained it. Can I just clean the liner and all other items with Clorox bleach and it solve the problem or do I still need to refill and shock it to kill the Mustard Algae?
Did you try this and did it work cause that’s what I’m attempting
This stained my pool liner,and it doesn't wipe off. Its very clean in parts of the pool then big patches of brown stains .
This stain is now part of my liner. You cant feel it at all
Should I mix it around so it's broken up and floating? Or is it fine just sitting on the bottom of the pool? Thanks!!
I believe u don't need to mix. Its chlorine resistant anyway. Just vaccum
Not sure if I have this mustard algae or not. The substance I have is not slimy, it’s a brown gritty powder on the bottom of my in ground pool. I vacuum it clean and then turn off the pump/filter overnight, wake up the next morning and it’s back all on the bottom of my pool. Also, we have a sand filter. What could this be from?
Same here
I have the same problem, pretty sure its mustard algea
Mine is brown in big patches not slimy or gritty, it's like brown stains.
@@robinluich6626 same with mine
@@robinluich6626 will nor scrub off?
How long typically does it take for the yellow algae to go away?
So does mustard algae turn into a dust? Or does sand do that?
So after the shocking and killing the mustard algae, does it settle to the floor and you have to vacuum?? Or is it just gone?
Can I use this method with out a pool pump?
You need a pump and filter for this
will vinegar in the wash clean bathing suits too?
No
If mustard algae is chlorine resistant as you said in the beginning, how does pumping the chlorine levels up do anything?
Resistant to regular chlorine, I should specify
No product recommendation for how to prevent it from coming back?
It’s in my sand in my pool filter should I get rid of that sand an bleach sand filter?
Great video
Love watching your videos
I’ve done what you said but it looks like a huge stain
Had it before and did what you said and it helped
Now ?
Maybe needs resurfacing ?
What color is the stain?
ok, love ur vids, but what do i do if i have an above ground pool with a bestway/intex? cartridge filter? 10,000 litre pool (not sure of gallons atm) and the filter pumps almost all of that in one hour, so it’s a good one.
i can’t filter to waste though! do u have any tips for this kind of setup?
i also just fitted a salt water chlorinator and have a tonne of mucous blocking up the filter. chem levels are fine. flow and chlorination are good according to the new system.
please can u help? we’ve already had a couple of weeks of 38 deg celsius and it’s not even summer. i just wanna use my pool and enjoy all the money i’ve spent on it lol
You're an amazing resource and person! Thank you for all the help. I recently started taking care of my pool. I always had a pool person, but my guy stopped serving my area. He was so good at what he did - a tad expensive, but because our pool was always so well maintained, we didn't mind. We hired someone new and within 3 months there are pool stains, algae, etc. The guy wanted to charge a small fortune to fix the issues. I fired him and just started figuring it out on my own. I still might hire a pool service in the future (it is a LOT of work), but I feel great I have my pool chemicals, DE filter, etc. in great shape all because of you and some helpful knowledge from local pool company, but mostly YOU!
I know you said it's rare but what if you have a cartridge filter? Seems like it's too fine to catch it.
When I used a lot of shock my pool turned purple. Why
My pool does not have a waist valve. It just has the four filters. How do I get the mustard algae out?
Is it same as silt
The water is super cloudy. Will this take care of clarity as well or do I need a clarifier? What about yellow out?
When I brush the mustard algae it just clouds all over. When I vaccum it same thing. My alkaline and PH are perfect and my chlorine is extremely high and I can't get rid of it. Please help!
Let the algae settle to the bottom. So pump should be off for 24 hours then shop vac it off the bottom very carefully. Took me forever to get rid of it but I finally figured it out.
I have a persistent black stuff in my pool it settles on the bottom and is very easy to brush but it keeps coming back. I don’t know what to do.
We have Mustard algae. We have been fighting getting our pool clear all summer and finally found out why. So my question is our pool is relatively small it’s an 18ft above ground pool. Would it be better to just drain the pool and disinfect it and clean it and start over?
His shock method worked for me, but it was ALOT of shock. I've got in an in-ground 25k gallon pool and this crap has been driving me crazy for a month. I got a little pool from walmart and put two lbs of shock to soak all the pool equipment in also. Make sure you get everything that has been in the pool sterilized of that yellow crap. Goodluck
What do we do if we have about 2ft of water at the bottom of our 16x30ft above ground pool, and it very clearly has mustard algae in it? We didn’t have our filter or anything plugged in yet because we are just at the beginning of the swimming season.
I have SO much liquid chlorine I don't want to buy several bags of Cal-Hypo to do this so can you just tell me what PPM of chlorine I need to maintain instead?
I have a lot of Mustard algae in my 5000-gallon pool ... Is adding a half gallon of liquid chlorine enough for the pool ?
Oh OH not sure if it matters but we are hitting 112 in Phx AZ
@@marciaz31 you need a cap or bag of yellow out and I would add an entire jug of chlorine. 2.5 gallons. 1/2 gallon will do nothing for alge bloom
@@jfiedler2386 Thank you J Fed ... I noticed that a pack of shock seems to help out a lot
Fantastic video! keep it up, some vids are sooo boring to watch and enjoyed yours. I have a 10x24 Intex pool, and mustard algae. I believe I have conquered the worst as my pool is crystal clear today. BUT!I have it floating on the surface maybe do to put algeacide into it? I have been skimming it off but it spreads as I do this. What else should I do. Thanks.
Before finally coming to the realization that I have mustard algae, I have been aggressively shocking my pool with liquid chlorine AKA sodium hypochlorite. With the high levels I have now should I still do as you say and shock the pool with calcium hypochlorite as the video suggests
After you do the first triple shock do you leave the pool filter on filter or do you leave it on circulate?
Always circulate
When can we go back in after doing all of that
@swimuniversity does this work for saltwater pools? Newbie here.
All the steps are the same, just use either dichlor shock or liquid chlorine shock (not cal-hypo shock: that can create calcium build up in your salt water cell). You can even try running the "superchlorinate" mode on your salt system to see if that helps.
What if I don't have vacuum to waste on my system?
I brushed my 5500 gallon pool and added almost an entire gallon of liquid chlorine, but the mustard algae was already settled to the bottom again and this morning it’s all still there PLUS some.
What do I do?! 😭😭😭
How do I find out what kind of algae I have?
My pool is cloudy but I can barely see the bottom of my above ground 18' round. Is that mustard algae or green algae? I've heard, mustard algae does not cloudy up. My pool is balanced and my chlorine is 20 ppm, but still cloudy.
You probably have microscopic debri to get rid of it just add a chemical called floculant it will sink all the microscopic particles to the floor then just vacuum it out to waste or you probably have poor circulation!
We just realized what we have is yellow algae. *#*% we have been shocking and putting in liquid chlorine and vacuuming to waste and brushing for weeks!! But this stuff still comes back and settles on the bottom! I just saw some videos that it is on all our stuff. Great. First of all is it hazardous to a person when they get in the pool to vacuum and brush?
Ok so after I wash down everything Do you recommend I put in Yellow Out? Or other algaecide? We are basically just trying to clear/clean the pool to get it ready to winterize it. Help!
I have a sand filter, I have no waste setting. I have closed, backwash, rinse, and filter. Any recommendations on what I can do ?
My pool guy already shocked the pool, how long till the algae is gone?
Do you need to backwash the filter while the triple shock is going on?
No. Backwash after but only if the pressure in the filter has increased 10 psi over normal running pressure.
So I have a 30,000 gallon pool and want to do the triple shock method. I need to make sure I’m understanding this all the way. Am I using liquid chlorine or the bags of powdered shock? Please let me know how many of gallons because I do know that if its bags of shock I would use 9 bags. Right?
I did 4 lbs for 15000 gallons.
I have a serious yellow algae problem in my intex 15x33 pool. Not 1 single vacuum has picked up the algae 😩 it just blows it all around. I don’t know what to do to get it OUT! Help!
What about adjustments based your CYA?
Only one way to lower CYA LEVELS.. u gotta drain about about half and refill..went thru this last year
@@bkmagic1349 I meant, adjustments to chlorine levels based on your CYA. I also drained pool to correct CYA it is at 50 now. I ended up using bio-dex knock out yellow and it worked great. The bromine in it did what the chlorine couldn’t. Ended up a little cheaper than triple shocking as I only had to shock once with knock out and then shocked again the next day.
@@johnedwardii nah..CYA just protects chlorine from the sun..as long as ur CYA is 30-50ppm....ur good..u don't gotta have chlorine at 5ppm if ur cya is 30ppm as an example
I have a 14,000 kidney shaped marcite pool in Florida. I have to brush it at least once a week to keep the algae away. It’s relatively uniform, not splotchy, and grows on the floor and walls of the pool. It’s yellow in color. Is it mustard algae or something else?
Sounds like mustard algae if it's yellow.
Didn't work. However Stop Yellow killed it in it's tracks. Disclaimer, we've been having a lot of rain here in north-east Florida and anything on the pool screen gets rinsed into the pool.
I’ve had good results using di ammonium sulfate for mustard algae. Follow the treatment with 2 pounds of stabilized chlorine granular per 15 k of water. The product I used (green to clean) recommended an elevated ph of 7.8+.
I get the gloves mask and goggles for the video lol but do you really where all that in the heat while cleaning or clearing algae? Still love the videos
You make great videos. I am In N. Alabama 95 and. humid. After watching your video I think I have brown rather than mustard algae. Salt water pool and chemistry is correct except I am 3 bags of salt low. 2190. I have vacuumed to waste for 3 days but every morning there is a slight brown layer on the bottom. I am going to triple shock it tonight thanks to your info. 18000 gal x 6 lbs of shock. Thanks again!
👍
When you say vaccum to backflush. I know some valves have 3 ports, 1 called waste. My filter is pac-fab (old) it has re-circulate or backflush. So do I move it to backflush to vaccum? Seems like my 20,000 gal. pool gonna be half empty before I finish. And do I clean the grids and add DE before or after vacuuming?
You didn’t say if we should turn off or on the filtration
I believe mustard algae is my friends’ problem. South Houston, sand filter. All summer we vacuum to backwash Butt, it’s back quickly and runs Kreepy Krauly as usual.
I am certain the sand filter needs to be addressed. I did get him to follow your steps once. (once, not all Three treatments)
Questions: any special instructions for filter?
If you’re instructions are followed will filter be clean?
It's so devastating!! No more waste mode. Just wasting water for nothing. It all comes back again
... I don’t even have a pool and I’ve watched all your videos 🤣
You’re ready for a pool
😆
New owner of a house with a pool. We have a pebbletec pool so I really can't tell if the debris in the bottom of the pool is dirt or algae. It clouds up when you brush and will make the pool super cloudy until it settles again. I have a Hayward 4 cartridge filter, with no way to bypass the filter to waste. I do have drain plug on the filter. I have read that i should not manually vacuum through the filter. Whats your best solution and what's the best way to figure out if this is dirt or actual mustard algae. As of this morning, The pool is balanced.
I’m sure you’ve figured out by now but touch with your finger and see if you can lightly “push” it.. if it goes up in a small plume and doesn’t settle immediately, it’s most likely algae and not sand.
Ive got it in a new pool (been up for a year) but nobody has been in it at all yet. everytime i think its gone it comes right back within a couple days. ....im stumped.
Does this work for salt pool? I have an above ground 24'. Thank you 😊
First of all i suggest against above ground pools running salt chlorinators because of rust issues. Second salt pools are chlorine pools. The salt ionier uses salt in the water to produce chlorine. The short answer yes, it will work.
What is a clear algae, looks like clear slim floating in the water. My wife gets it with a leaf skimmer with a fine mesh. I think we got it. Saw it last summer when we were into swimming about a month. What is this jelly looking stuff ?
Will this method work on salt water system.
Yes it will work. Make sure you shock with sodium bromide to help kill it and keep it away! (exa. Yellow Treat)
Husband went to close.pool. brushed n shocked n then back washed. Bunch of yellow he says in the sand filter. Meanwhile he lowered the water n ik expecting so cant even shock it now. Help!? Its cold enough to close so it shouldnt grow until spring but wht can I do? Add bleach straight to the sand filter?
I have a salt water pool that gets a lot of sun. I get mustard algae on a weekly basis, sometimes every couple of days. I’ve tried a lot of algicides that are specifically for mustard algae. Nothing seems to work. What should I set my salt chlorinator to if I’m going to try this method you mentioned?
Anything worked with ya?
I have the same setup as you and always get mustard algae as well. Any success in getting rid of it?
Rare,, hell I get it all the time.
What
I get it all the time also. And I’m in Michigan. And I don’t ever swim in lakes or ponds that it could transfer from.
Got it here in Massachusetts, second summer owning a pool. I think I got it from my plastic ladder that I dropped in. It was laying in my lawn all winter. No idea. Time to buy some bleach!
It is my NEMESIS!!!
@@emilycooke1726 mine is back! Another round of algi treatment
I just installed the PoolRX into the skimmer (from your site). Within 24 hrs, I'm seeing this. Thought it was sand from the sand filter but it's not grainy. I thought going to a mineral system was supposed to prevent this ("eliminates all algae")??
You freaked me out when you said my name in the beginning!!! 😂😂
Thanks for your video. I have a problem with mustard algae. I did your process and it didn’t go away. Tried 6lbs of shock the second time. Seemed to go away for a week and now it’s back. I have done everything. Not sure why it keeps coming back.
Will flocking help?
I am in Arizona and just had a run-in with the mustard and I use liquidated chlorine shock instead of what they recommended. I added 1 gallon for my 6600 gallon pool. worked like a champ. putting chlorine puck in my skimmer to keep chlorine levels slightly elevated and evenly dispersed in the pool.
I fight this stuff every year, but my pool is out in the middle of a conservation area right smack between 3 ponds. Evidently it’s commonly found naturally on trees around ponds. I highly recommend following these guys instructions as they have worked for me and balancing that ph and getting the right amount of chlorine seems to be key. Also you’ve gotta be prepared to waste the hell out of the water to flush it out of the system and get it out of the pool. I’m hooked directly to a well with the pool, but if you’re in town that’s gotta suck. I’ve heard there are methods at filtering it out of the water but only directly flushing it out has ever worked for me. Goodluck to anyone else fighting this crap
Sorry you have to constantly battle this, but glad pH and chlorine balancing has helped!
So I just did the shock the sh&$ treatment overnight brushed it again this morning because there is still algae on the walls. Mostly in the deep end. And now in looking at it again it appears green to me. Help! Can’t scrub hard enough to get it off the walls.
If it’s chlorine resistant, wouldn’t cleaning your pool toys with Clorox bleach spray be ineffective?
8 week old pool plaster. Tahoe Blue Diamond Bright. I'm dealing with 1 week plus now possible yellow algae or metal stain. Pool was 99% covered equally with a yellowish/light brown somewhat slick substance. I'm in Houston. Had major landscaping jobs with lots of fertilizer AROUND the pool done, but was careful to remove debris immediately. Some leaves, branches, mulch fell in pool but I was right there with the skimmer to clean it up to ensure it didn't stay. Organic matter was a concern when we moved in (two months ago as well) so we removed most of our trees and bushes in the back near the pool other than a large Magnolia tree which is next to go because it sheds too much. One day the pool was blue, literally the next it was covered. I was treating a brown spot from tree dropping with a little acid and noticed it was bright blue. Compared to the rest of the pool I realized that I had a problem. First test showed 8.0 PH and low chlorine. Starting lowering the PH with 3 gallons of acid and the material washed off immediately on the steps and areas I poured it into, however everywhere else was really unaffected. Seems like it all happened after the landscaping jobs, fertilizer, mulch was all done-despite ensuring nothing was getting in the pool. Perhaps the rain washed fertilizer into pool and caused a metal reaction? I used Ironite on the plants which obviously could stain but was careful not to get anything in the pool. Chemicals were checked weekly perhaps a little less than they should have been admittedly. Chlorine a little low. Phosphates were 1,500! Two different pool stores testing my water said to get rid of phosphates, quadruple shock, algae feeds on phosphates, etc etc. Pour the chlorine in-gets a little cloudy brushing even with wire brush doesn't do much. I have triple shocked the pool 2-3 times in this time, running a perfect PH and got phosphates down to zero. After a few days got water perfect. Pool plaster company is blaming chemicals and that it's absolutely yellow algae. I hired another pool company to come out and they tested, felt, brushed and looked at the substance and said it was not algae. Especially after the high chlorine and shocking. Pool stores testing water gave me yellow out-and it immediately got rid of whatever it contacted, but those are very small bottles. Pool stores are saying it's not algae, that it's stain from the phosphates. My metals were little high one day, but nothing crazy. Been testing water every day. So far the only thing that lifts the stains is yellow out or acid, but just in small areas. Was told that I should drain and acid wash the pool. I have a 16,000 gallon pool. Changed filters and there were huge clumps of green smooth and slimy matter all over the filters and chunks in between no doubt slowing the flow. After the change pool seems to be getting a LITTLE better but not as fast as I'd like. Pool plaster company wants me to dump hundreds more of chemicals and snake oil into the pool... pool stores laughing all the way to the bank and my arms/back are sore from scrubbing. How long should this stain persist? And how do I know what the heck it actually is??? I've got about $600 in a little over a week in chemicals and filters and dozens of hours brushing and still about 75% of my pool is still covered. Only the steps are starting to show the beautiful Tahoe Blue new plaster color I was seeing a little more than a week ago. Please help! Thank you!
Oh man that's very sad. Is it OK now??
I treat with yellow out add a jug of Chlorine and the same time. Then follow up the next day with another jug of chlorine. COMES BACK IN ABOUT A WEEK :( what do I need to do????
Is mustard algae gritty? I have brushed and brushed and it's not coming up...I have spent hundreds of dollars!! Every time I go to the pool store he tells me to get something different!!! Help!!!
We have mustard algae only on our sun deck area. No visible algae in other parts of the pool. We have brushed and treated according to our pool service repeatedly. Brushed, treated and shocked. Still settling on sun deck. Is there something else other than tutorial advice we should do?
Balance pH , consider an Algecide or yellow out
not sure what i have , looks like yellow mustard, but stuck to liner in the whole shallow end wont come off, tried everything pool is only 7 years old? been shocking quad amounts, brushing , will not come off liner, inground pool , any suggestions anyone? thanks
Can mustard algae appear gray?
Can I just sink all my pool toys in the pool to disinfect them? I feel like that would be easier and more effective than trying to wipe down every nook and cranny.
That’s what I was told to do.
I thought you had to use sodium bromide and cal hypo to kill mustard alge effectly?
Yes! That mix causes a hypobromus Gas! Which kills the mustard!
This is correct! or else its just gonna come right back. 1 cap of yellow treat and shock will do the trick.
Will this work in a salt pool?
@@SouthnKYgirl.aneshad yes it will
Skew balancing becuase super chorinating is going to push your PH up up up, get rid of the algae and then balance
I have spots of an odd, very light colored substance on the bottom of my 6,000 gallon vinyl pool that kind of looks like sand. The water is crystal clear and balance (because of your videos) It doesn't stick to anything and turns to "dust" when I even touch it with my pool brush. Do you think this may be yellow algae?
This is also what I'm seeing, but I don't know if that's what I have either. It's not stuck to anything at the moment.
This my same issue
