G'day mate. Hope you can answer me this one question.
Do I need to leave the light on for my brine shrimp all day and night after I have moved them into a grow out tank?
I have a heater in there with them.
my water is literally liquid rock and i wish i had soft water but it does help with live bearers
Same here
Ya Cali hard
I had a black water tank... Ph11... **sigh**
Reverse osmosis is your friend.
Get some cichlids
Well, you know my hard water fish of choice, but some of your choices were rocking. The Odessa, Congo, Flag Fish ... really cool. Hope you're well Cory and that your shop is thriving despite the COVID-19.
Just wanted to tell you how much I appreciate you. I love learning new things and you never fail to bring the knowledge. You have an excellent way of explaining things.
Cory, you are so awesome! I LOVE all your educational videos and you make the hobby much more fun and way less stressful by sharing all your knowledge!! I am very impressed. I have had fish for 30 years and I just now am getting back into the hobby after 6 years. So excited to start buying my fish! Tank is ready now. Thank you for all you do!!! Fishes LOVE you from all over the planet !
While my Congo Tetras breed every morning at 200 ppm, They are not hard water fish. They come from the upper Congo. One study that I read on their habitat measured the TDS at 10ppm! The upper Congo has super soft water. Most people think of African waters as being very hard because of the rift lakes. These lakes have formed in a very deep rift valley. Since there is little outflow the dissolved solids keep building up. New water is added through rivers and runoff but most of it leaves through evaporation. Over the millennia the water in the African rift lakes has become insanely hard. The Congo is different. It is rainwater flowing to the sea over substrate that leaches very little. It is similar to the Amazon. Tanganyika does outflow into the Lukuga, which is a tributary of the Congo. The Lukuga has hard water but I cannot find any reference of Congo tetras living there. Once the Lukuga merges with the condo the hardness is diluted.
Cheers,
Chris
Water in the lake Malawi is not insanely hard though!!
.
Great information. Thanks for sharing.
I have Congos with a Bristlenose, and with 7°pH and 10°gH (6°kH) all of them are seemingly doing well. I actually mix my tap water with a 50+% osmosis one, because I have very calcareous water which isn't even good for many hard water fish (i.e.: I had platys, and have to give them back because they were suffering!), which actually generally want a more balanced presence of minerals, but it might have worked fine for Rift Valley Cichlids. Just, I was worried about having to manage their aggression levels, so I decided to go for softer water.
Just check your mineral contents, because even if we talk about "hard water" fish, there can be differences: the same mineral content which works for Poecilids / livebearers might not work for Malawi or Tanganika Cichlids, and vice versa.
Hey Cory I just want to give my personal thanks for helping me treat ich, the Ich-X treatment worked wonders in my tank. I had two baby rasboras who looked on the verge of death, and 10 infected adult rasboras, six infected panda corydoras, and an infected betta. None of them have any signs of ick and I'm only half done with the treatment.
ME TOO just a week in to treating my tank using ich x. Only one or two fish with 3 spots max ALMOST DONE
Yep he saved me too
I have liquid rock water pH 8. My best thriving fish are Honey Gourami, Pristella, Serpae, and Emperor tetras. My Praecox rainbows are hanging in there. I had no idea Congos do well in hard water. I would love to stock them in my 40 gallon breeder. Thanks, Cory!
They don’t he might have gotten mixed up, they prefer softer water
I was literally looking for this video yesterday . Then you make it the next day 🙏🏼 what a guy
Thanks for focusing on hard water this week! Appreciate it!
This video really helped me out. Thanks Corey!
I love your blog! Thank you so much for taking the time on them. Excellent
Nice to see a video for hard water. In my corner of Arizona, our water is ridiculously hard. Great for my guppies but I struggle with bettas. I really like that Dwarf Neon Rainbow.
Thank you Corey for all the information!
Man the tap water in my house gives me a soar stumock after one glass...but the fish love it..
Fun video. I think the American Flag fish is a super underrated fish in the hobby. They devour hair and BB algae and are fascinating to watch because they’re always pecking away in search of a morsel to eat. Keep up the great work!
Wow. A lot of these fish are just beautiful. I can’t wait to get back to the states and do more with the fish hobby.
I really want to get some congo tetras someday 😍
I love livebearers, specifically swordtails which I'm surprised didn't make the list good size, hardy, come in a rainbow of colors and fairly cheap.
I am on my first aquarium, a 10 gallon. My tap water is TOO HARD and in the red listed as 300 mg/L on a dipstick test. I was able to successfully use a ZERO WATER filter pitcher to do a 50% water change and voila! The water testing now shows OK between 75 and 150 mg/L. I'm so happy and looking forward to adding livestock soon! Fancy guppies and cherry shrimp.
Keep it up Cory! Love these videos
Eeyyyy, my man. Thanks for doing this for people like me who were super anxious about it when I first came back to the hobby in my new home with super hard water!
Being watching g since the start and love every video!!!!!
That Crinum Calamistratum in the background tank looks amazing!
You been killingnit with the videos bro keep it up
It's so funny. People want what they can't have. We have hard tap water, so in our aquarium community livebearers are frowned upon and considered not a cool fish at all. Something for kids to keep. Instead aquariumists here go crazy for soft water species like discus, Amazon species and so on. They build Ro set ups, buy distilled water, remineralise it and keep a lab at home to recreate that water. 😂😂😂
Thanks for the ideas!
Thank you....... I needed this video. Really love your videos!
Love the videos!
I keep a lot of Red Wag Platies & Guppies. Some of my aquariums have a GH (degrees of hardness 20-30). It seems that they breed more in even harder water than that. Amazing fish. Good video. 📺👍😎
Rosy Barb & Red Eye Tetra are also great shouts. Great vid :)
Thanks for the suggestions!!
Love the content keep it up
Great video. That thumbnail is really well done. Nice job!
Great vid. Can you do a top 10 plants that thrive in hard water?
Good information as usual
Thanks for this info. My water hardness is at the top of the charts. pH is neutral. I will definitely be looking into these fish.
Great video, pristela tetras are my favorite tetra.
The golden killis are great but quite a few of the African killis do surprisingly well, clown killis won’t tolerate very hard water but are happy to be over 7 can even breed. But the one I’d like to highlight is the firemouth killifish or epiplatys degati. Extremely hardy fish can really keep it in any water, bred them at at ph 6 and 8. And they’re cheap and males in breeding form are gorgeous
Excellent video!
Good advice,even if you live in a "hard" water area,the local stockists will have "soft" water fish and in my experience these fish will look like they are doing fine in hard water but their lifespan is dramatically shortened to say a year or two instead of five.Obviously they will be extremely stressed but being fish,it's difficult to observe this,although I must admit the water around here is hard but not extremely hard.✌👍
Thank you, i am going to set up soon fishtank and i have hard water. thank you for very informative video.
I keep GW killis to keep my guppy fry population in check. (I know some people think that's horrible, but...) They can get dicey and attack each other. I was growing our 4 fry- one inch fish in a 10 gallon- when 2 males turned on a female and tore her apart. Another one avoided the lid and got into the HOB filter impeller! How the heck that happened, I have no idea! Keep the videos coming, you are awesome!
Don't know about your experience but coming from the aquascape side, a limestone heavy scape will keep the KH high constantly and you will definitely get hard water. Definitely easier to achieve hard water than softwater because the only effective way is the RO route.
Please do a top 10 soft water fish also :)
Since you mentioned Golden Wonder Killifish, y'all should search on UA-cam "Golden Wonder Killifish jumping out of the water to catch crickets" to see some amazing natural feeding behavior. I NEVER would have thought they could jump that high! Very beautiful and cool fish suggestion.
Thanks Cory
Beautiful! But I find the Congo tetra to thrive in a neutral ph to slightly soft. I even mix purified or rain water to get them breeding.
Agreed, congo's don't like hard water.
The average TDS in the Congo River is 10ppm! That is incredibly soft water. Although my Congo tetras spawn every morning at 200ppm.
Cheers,
Chris
@@Cgraseck 200 ppm is still kind of soft water!
Great video. Looking to get a guppy. What fish would be good to add to take care of the algae regarding the hard water condition?
Hey Cory, would I be safe to use some limestone rocks for decoration with some of these hard water loving fish… assuming I cleaned and prepped the rocks so not to introduce any harmful to the tank?
I have some really neat looking limestone rocks on my property, but I’ve read they will increase the ph too much. We also already have very hard tap water here in Missouri, possibly from all of the limestone we’re on top of.
Thanks !!
my tap in so cal is super hard... ph is almost 9 too, 8.5-8.8... is this ideal if i wanted to start a shell dweller breeding project? i feel like the ph is a little high...
I have hard water and I am really glad for that being Guppy NERD :D Great video again Cory! :)
Hello, i have a question. Have you tried using seiryu stones with betta fish? Is it safe in the long run? It makes water hard and ph high which is bad for betta.
One of my favorite things is to make lists and cross reference you videos😂 Kinda nerdy I know but I don’t care!! Just looked at your ideas for a 55 gallon, cold water fish, and hard water which I definitely have here in Arkansas. According to your test strips that I ordered from you guys anyway. My tank already has 3 albino corys, 14 swordtails that were rehomed to me from my friend, and 2 mystery snails. Thanks to your handy videos, overtime I want to add guppies, sunset platys, and maybe Odessa barbs if I can find those. My other tank is a 36 and it has tons of plants that I ordered from y’all as well and they are doing awesome. I feel all fancy and worldly ordering plants from Washington state for my aquarium 😂😂
I'm coming off of a 15 year cichlid tank and would like to get guppies mollies etc. I dont think I have hard water but my substrate is dolomite, would that be enough?
Yay. I have liquid rock water so this was nice lol.
When you go to sell them do you need to acclimate them to softer water first or would you just sell them. I have well water and I wouldn’t want to sell something that wouldn’t make it in the softer city water.
I have a question, I have a 20gallon with 6 mollies 3guppies 3platies and a female betta and a bunch of molly fry in there. I’ve had them for like 3weeks. The adult fish don’t seem very active now as they were when I got them. They eat well but tend to stay stationary at other times. The Betta is doing fine. I’m using drinking water and I don’t have any water testers to test the water. I have kept these fish 10 years ago and I didn’t face any issue,I used the same water at that time too . Can anyone help and is there an aquarium coop community that I can join?
7.8 with tons of calcium here in Sierra foothills.Thanks
Just sent in an order of 100$ plus of food, filters and media. Thanks for the great info and posting up your advise from experience, subbed and thumbs up!
I had 2 neons one died the other is hanging around on the bottom, is he lonely and will he die?
My tap water is neutral (7.0) and hard. I've done well with Giant Danios, Black Skirt Tetras, Black Neon Tetras, Serpae Tetras, Ancistrus and a Bolivian Ram. Bettas, Gouramis, Neon Tetras and Beacon Tetras haven't done as well for me.
Perfect video for where I live. I have very hard water.
thank you so much i have pineapple platies and my gh was 180 thank you for this information
I'm from the Philippines, our tap comes from deep well and is super hard, I had to do the complete opposite and create soft water for my tetras.
Is their any cold water fish . My ph tap is like between 8.2 to 8.4. Very hard water. All my fish because of high ph might have to go warm water fish.
A lot of Australian fish are tolerant of hard water, such as Empire Gudgeons, Crimson-spot Rainbows and Pacific Blue-eyes (Delicate and Honey Blue-eyes are soft water specialists however).
Good info, thank you. Is RO water still good for guppies ?
No
Hi, I'm Max from India..I have 7 guppies and 12 pink zebra tetra in a 100-gallon low-tech planted tank and I'm using groundwater its TDS is 2000 .however fishes look fine...i also add fertilizer of the 2hr Aquarist on MWF 3 ML . however im thinking to add more fishes which fish you will recommend for this tank?
Living in Southern California with ph almost at 8 out the tap. Good thing most species have adapted to all levels of ph. I have kept and bred angelfish at this ph. Too bad I need ro water for discus. Wish I had your water
Same here in norcal. Apistos, dwarf puffers, shrimp and angels seem to thrive. Can't keep Rams and discus though without RO here.
I have the opposite problem of you ,I have very hard tap water .... so my livebearers thrive , still my rasboras , bettas , flame tetras and barbs do well but I know my water parameters for them are not the best as the water is probably too hard for them
What about dwarf gouramis? Do they also work fine in hard water??? I have hard water and want to keep dwarf gouramis. My guppies, Danios ans tetras are already doing well. But I'm not sure about dwarf gouramis whether they will do well in hard water or not!!
This is great - my water is liquid rock. Now do one for hardwater unheated tanks! Thank you!
Hey cory I am having problems keeping jungle val and propagating
Them. Got any suggestions? I was thinking of keeping brazilian pennywort with it, just dont know whats wrong
Keep some hardness in the water, root tabs and time.
@@AquariumCoop thanks man. My tanks dirted. So thats why I was trying to figure out why the stunted growth. Will think of additional root tabs now.
I'm setting up a 32g fluval flex and have hard water with about 7.8ph. I REALLY want about 20 green kubotai rasboras. Do you think they will show that amazing green color in my water. I once had glowlight danios that came in absolutely gorgeous but lost all their colors in 1 day of being in my hard water, and I don't want that to happen with the kubotais. Your thoughts?
I've ordered java fern, anubias and water sprites from your site and am seeing good growth using easy green.
I got a small female betta that seems to develop horizontal stress stripes whenever I turn my tank light on. I'm quite sure the stripes are from the light/reflection as the water parameters are good. Any tips?
I have really hard water I mean it's all the way hard which my platies and gubbies seem to love but I'm thinking I'm over oxygenated my fish is that possible I need to find out nonetheless ones in the planted tank are doing great but I had a platy small one die this morning they were fine last night???
You mentioned Congo Tetras, do you think a Congo Spotted Puffer would do OK in hard water with high PH? My tanks ride around 8.2
Chad why don’t you just google it bro lol
Hey Cory when are you gonna have dwarf baby tear back in stock
I am on a well and I have hard water I am currently keeping swordtails, serpa tetra, angel fish, Cory cats, plecos, rainbow sharks, black moor, and my sons fair gold fish. No problems with any of these.
My GH is around 400ppm or higher. My ph ranges from 7.8-8.2 out of the tap. Wish I was one of those people with 7.4 out of tap lol
Same lol
That's what I used to have - it was like a direct tap from Lake Malawi. My Mbuna loved it. Now I have hard but neutral water and debating what to do. I'm a fan of choosing fish that will thrive in what you have and not needing to change it too much.
Any ideas for algae eaters for hard water? I have a platy tank with snails and ph at 8.2 and I’m looking to add some more fish to it
Flag fish, bristlenose plecos. Tropheus
Get some mollies!!
@Awuarium Co-Op Cory, what plants work well in hard water? Because in my hard water tanks, the plants don’t do as well in the Chicago water, my tap gh and kh are very high, I transport Chicago water for 3 of my tanks.
Vallisneria, anubias, java ferns, crinum calamistratum would all work.
Thank you.
@@AquariumCoop all the species I have.
After choosing carefully plants and fish that naturally like water I have, my aquarium looks beautiful with very little effort.
What is the next fish for the 800 gallon and will scuba Jimmy make an appearance in the rescape scuba Jimmy is the man. ✌️
Would any of these species (or other hard water fish) do well in a 10 gallon tank?
I’ve always read that Congo tetras do fine in neutral ph but prefer softer water, I defiantly wouldn’t say they do well in hard water all… might have gotten mixed up there Cory!
What's the required pH for glass fish?
Do roseline sharks like hard water?? Or can they tolerate it?
Some of your recommended tank mate are not compatible due to temperature requirements.
Rainbow fish for example are a cooler temperate fish wile the congos want it nice and warm
What about plants specifically for hardwater?
Vallisnera, pomatogeton, lilies, crinuim
What kind of lillies?
@@justinerdman21 ive had good success with a common pond lily, i dont think it was anything special but my only caveat for using a pond lily in aquarium is that it will get HUGE and pulling it out will be a nightmare. otherwise if you dont plan to move any time soon its a great option for cheap
others have said vallisinera, and i agree there. along with that ive had great success with water wisteria, hygrophila, guppy grass, dwarf sagg, and bacopa
I can agree with val... my v. Contorta TAKES OVER tanks when added(assuming adequate light) also have had a lot of success with water sprite. Just looking for more options.
I'm setting up a tank for the preschool I work at. And, yup, liquid rock. Thinking of being adventurous and trying shellie s.
Shell dwellers are fascinating and a great choice for hard water.
Someone give this man hard water!!
My KH is 3, GH 4 and PH of 7.4 from the tap. Whats the best way to raise KH?
Same here!( except higher PH) and wondering the same! I’m trying oyster grit rn.
@@spiraleena9237 im just trying a product and so farnso good, its called JBL Aquadur take a look it may help
Love to see the flagfish get the respect it deserves! Natives as a whole need more attention
Looking for ideas, my pristilla tetra are breeding like crazy.
I live in Colorado and the ph is 8.5 to 8.6
Interesting how different the water is just miles away. On Whidbey Island we have hard water on the island.
I practically have rocks coming out of my faucet, to the point that it's just.. Horrific. But I live in the Cement Capitol of the world, so feels like it fits, heh. Still trying to work around it, just set up my first tank in 25 years, wanting to get into fish and shrimp and crabs and... you get the idea XD
Can mollies survive in water with a 1000ppm of hardness
P.s. also include gauramis and carps(small about an inch...yellow)
As someone who has high tap water (200+ ppm) I gotta said I wish I have your soft water keeping bettas would be a lot easier rn
Also when I put my water in the tank the hardness lvl goes up to like 400 ppm and I think it might be because of all the stones in my aquarium. Does anyone know if I should remove them and redo my scape or is there an alternative to fix this issue
