Nutrient Supplements for Aquaponics Systems | Test Results
Вставка
- Опубліковано 30 чер 2024
- G'Day Folks. Had the nutrient level in the aquaponics system tested & thought it would interesting for fellow aqua growers to see the results. I also run through the nutrient supplements that we add on a regular basis.
Will be posting a follow-up clip on how the amendments are going in a few weeks time.
Hope you enjoy this quick update & your gardens are booming.
Cheers all. 🐟 🌱🍅

Can we use organic fertilizer for other Nutrient deficiencies.?
Are potassium bicarb and calcium hydroxide, chelated iron are they safe to fish.?
@@samsunny6483 Those ones are safe for fish. 👍 I would recommend only using organic fertilisers but not ones that use a great deal of nitrogen or ammonia as there should be more than enough in the waste provided by the fish.
In such rying times, it is wonderful to see Rob Bob being Rob Bob.
Thanks. 😁
Hope all are well with you & yours.
You are doing a grand job Rob...I loved the "Can't grow fish in soil" comment some people just don't get it do they.
Thought it would help to get it out of the way early Dave. 😉
Man one of your best educational vids ever. So much info, I’ll have to watch this one a few times. Saved to favourites.
Glad it's helped some mate.
Cheers David. 👍
Keen to see any new tests by the way mate. I found this report of yours and this whole video really helpful cheers heaps.
Glad it helped some Mitch. I haven't done another yet but will look at sending some water through late winter/early spring (Aug/Sept).
Cheers mate.
Awesome stuff Rob. Good to see you taking it to the next level for all your viewers.
Just bumbling my way through mate. 😉👍 Would have done it a lot sooner if I had the coin.
Wasn't too keen on doing additive clips folks request without knowing what was in the water beforehand.
Hope all's going well with you.
I ❤ your garden. Boc Choy is some of my favorite greens...gives me inspiration to have a go at growing some in my garden. Cheers from Atlanta GA USA.
We're going to be picking one or two for dinner tonight Phil.

brilliant video today Rob, mega interesting. 👍🏻👍🏻👍🏻 cant wait to see if the micro nutrients come up. I panic about adding anything to my system. Great to see someone going all out, and sharing.
Hope to have another test ready to update on in about 8-10 weeks time Mike. Might even do some tissue samples to see if the plants are taking up any in non soluble forms from the minerals as well. Won't be a definitive test but I am very interested to see what turns up.
Cheers mate.
Best Augaponics page I've seen so far. I've all I need to build a drip and sprinkler system. Your page will help me a lot. So I'll get the frame done around mid September.
Hope the build goes well Jerry.
Excellent as always mate 👍
Thanks 👍
Hope all's well with you & yours.
Thanks for sending me this way!
No problem mate. 👍👍
GOOD TO SEE THE TEST.
Hope to have the follow up ready to share in about 8-10 weeks time.
Cheers.
awesome information Rob
Glad I could help some.
Cheers folks. 👍
Great vid as per usual
Cheers Knife. 👍😁
Good clip Rob.
Thanks Mike. 👍
Hi Rob, Sue from Nz here. Thank you so much for your awesome videos. Haven't seen them for a while so need a good catch up of Rob Bobs TV😊 haven't done much with my system in the last year so needs a good tune up and clean up. Amazingly my fish have survived even if the plants havent done too well. Thanks again for the easy to follow science of nutrient deficiencies and links to tests and supplies!
Hi Susan. Is good to hear the system is still ticking over. 👍
Are you adding much other than just the fish food?
Cheers.
Not really, occasionally I'll put in some liquid seaweed but I'm guessing with amounts and I think the actual problem may be my ph sits around 8.2 and I can't seem to bring it down. Even though I painted my tanks I still browny green slime on them. I also have old roots through my grow beds but I've put in a hand full of worms into each grow bed and I thought that would fix that. I only see 1 or 2 occasionally so maybe they've got through to the tanks and been eaten?
Love it Rob. Started my system over the winter and planning on putting bed outside the house soon spring is here. 50 brown trout and seems to have cycled but need to nail down cal,potassium, iron and magnesium to start.
Nice one mate. Hope they grow well for you Ed. 👍
Howdy from Texas Rob Bob. Enjoyed your video sir. Keep up the good work.
Thanks folks. 👍
Another great video sir.
Cheers Aaron.
have a top one mate.
Great clip Rob thank you. To make it easy to add nutrients i find it useful to embed a shallow cup under the inlet pipe. That way you just dump the powder into the cup, it dissolves and the water overflows into the system. You do get a bit of algae in the cup but its easily cleaned.
I used to do that with the old system. Just can't find the pipe sections I used...
Cheers Rohan & have a top one.
Very interesting video. Ive had my system just on a year now and didnt think about any nutrition deficiencies till i noticed in the leaves on a brocoli since added some addatices they have bounced back
It doesn't take them long to pick up once they get the right elements. 👍
Hope all's well with you n k.
with that soil additive I would stir it into a 25l bucket of warm water, leave it to sit for a while, pour the clean water into your aquaponics then use whats left on your garden.
Most of the elements in there won't be water soluble so best to add them all I think.
Just added the first lot of 600g/1.3lb.
Very interesting thanks!
Hope it helped some.
Cheers.
GRATITUDE 💥💥💥
Just what I needed I have been having a few issues myself. This is a very much needed video. Thanks again God bless
Glad it helped some Robin.
Happy growing. 🐟🌱🌱
You should add a link to true aquaponics as they already sell all of the fish safe nutrients you need including the micro-nutrients. I bet he would send you some to trial too.
Not sure it would be economically viable to send to Australia but thanks for thinking of me. Am sure I'll be able to find what I need here.
Not sure I'd feel comfortable promoting something i have no experience with either.
@@RobsAquaponics They are the biggest sell of aquaponic nutrients by volume in the US and the only company selling all nutrients from top to bottom you might need including subscription and testing options again far ahead of the rest of the industry hence why i suggested them.
@@RobsAquaponics I will send you a Facebook message, it will come from Roger Terri (she's the wife), give me a quick chat when you get the time.
@@trueaquaponics6825 👍👍
Hi Rob, Thanks for the great info. I’ve just finished cycling and have planted seedlings. Got a bag full of old fish bait in the sump and am adding power feed to the beds to keep the bacteria happy until the fish go in. I have also stuffed 4” filter socks with work casings, tied them shut and buried them in each bed in an effort to help with micro elements. Might add a couple to the sump as well. Thanks again.
Nice one Andrew. Have the uniseals turned up yet?
Cheers mate.
@@RobsAquaponics I’m away from home for the rest of the week mate. I’ll net you know when I get back
@@andrewstrutt6048 Cheers mate.
Namaste Rob, I’m from India and I’ve set up a vertical NFT Aquaponics system of 48 plants at home as a hobby, I do not understand what kind of supplements I need to use as I do not have access to these kind of nutrients.
Thank you, great video man, I learnt a lot
You could do the magnesium test at home if you can obtain sodium hydroxide and sulfuric acid.
However, you would probably need to buy a much more precise scale (milligrams) and take more water from your system (5 gallons)
The $80 is probably worth it 🙃
Thanks for all the great info! I hope to be able to start my own system one day.
Not sure I'll continue to pay to get tests done Timothy. I was going to send one off the other week but the bills had to come first.
Will send one off next week & will post the results on an upcoming clip.
take a close look if at your no3 for a couple days when you add those things i also had extremly high levels, than i dosed aquarium fertilzer and it went from around 400 to like 10 ppm in 2 days and my plants starded doing realy well, i have even like a 90% of the seeds i trow in there come out :)
I saw a small jump Jay but not a lot.
Added it all in this week so will be sending off another test at the end of the month to see how thing are looking.
Cheers.
Hi Rob,
I am prettu new to this feed, but I am enjoying it immensely. Can you advise how much time you spend on a daily basis managing your system?
Hey Colin. Probably only up to 5min most days which includes feeding the fish (less than 60sec), going over plants looking for pest/disease & harvesting so a lot less than someone that needs to water their garden daily.
About 15-25 is added on filter clean days.
Hope that helps some.
Hey Rob are you planning to do a video about the rock minerals (wicking beds + AP)? Thanks and keep up the good work!
I hope to at some point. Just need to set one up myself first.
really appreciate the video Rob . ive been doing aquaponics in conjunction with worms for about 12 yrs. knowing the nutrient composition has always been a black box. have you compared fish food for nutrient/mineral content? have you found a difference in plant growth with identical set ups utilizing different types of fish (i.e. herbivorious vs carnivors? i have only used goldfish, KOI, and turtles.
I have asked the feed producers if I could have a breakdown but they guard that information fairly tightly.
I've only ever run one system at a time here due to space issues & with the omnivorous Jade & Silver perch.
I want to set up 2 identical systems next to each other at some point but more to test different plumbing arrangements rather than fish types.
Chewers Richard & happy growing mate.
Great job on vid!!! One question can you mix de calcium and the phosphate for ph bust? Cheers man
I'm not sure about mixing it in the forms I have. You can get calcium phosphate fertilisers so it may be better for you to research them.
Hope that helps some.
well done ! thanks so much for sharing your knowledge . do you have a platform to share photos with you of our systems?
I put a call out for folks to pop them up on a pinned post on the Facebook page wall so you're more than welcome to pop them up there. 👍

Cheers mate.
Hey Rob, thanks for your vid! I got a question, can we still consider your plants as Organic now after you've added those supplemental elements?
I see "organic" as a certification process so I don't like to use that label anymore & prefer "chem free". I know that's splitting hairs a bit but such is. 😉
All the elements I'm adding are base elements from nature or are allowed inputs under organic certification for farming or as a food additive as I understand it. 👍
Cheers & have a top one.
Hello, Rob! Nice show. I just wonder if you use 1 percent o 2 percent feeding ratio? do you have a mineralization tank? Nice video ;)
It depends on the water temp & size of fish as to what I feed them. 👍
At the moment they are getting about a 1-1½% feed rate at a guess but won't know for sure until the weather warms up a bit & we can weigh a few up.
It's best to ask the hatchery where you get your fingerlings what they suggest as they will have a better idea for the species you pick & your climate.
Hope that helps some mate.
Happy growing. 🐟🌱🌱
Wait, I can't grow fish in soil?? damn it now 'Ive got to dig up my 50 trout what the hell??!! 🤣😂👍🏻 great point, well made, my hat tipped to you sir 👍🏻
🤣 Cheers Mike.
My fish frames end up in the soil havent grown any fish yet 😂
@@Kearnesy 🤣Give em time mate...... 😉🐟
How many letters is your system in this video.?
Thank you for another great video.
Oh is there any other way to subscribe others than UA-cam as they no longer accept PayPal?
Hi Warren.
The system is about 1600L/422gal in volume when the sump is full. 👍
Unfortunately Podia (the mob hosting the Farm Your Own Yard site) doesn't take paypal either, just the common cards (Visa, MC, etc) which is a pain in the rear.
Can chat privately via email if you want but am happy with folks just thumbing up the clips & sharing them with mates. 👍
Cheers mate.
Hey Rob, I wonder if you can use aquarium tests? Salifert makes a potassium test and there are phosphate strips that could test up to 100 ppm.
I know they make a marine (salt water) test but I remember being told that it's not suitable for fresh water. I really should have checked with the company though as it could be OK for fresh water.
I wonder if the zinc is high due to water splashing off the galvanised steel mesh used in the fish tank cover?
G'day folks!
Howdy Tom. 👍
@@RobsAquaponics great content mate, thanks for helping keep me sane in isolation. Plan on getting my own aquaponics system going in the next few years once I've got a bit of land haha.
@@tomwatkinson7744 Nice on Tom. Hope you can sort out something soon mate. 👍
Hey mate, just wondering if you have ever considered mineralising the fish waste to get some of extra nutrients?
I have & would like to but room is an issue at the moment. Will be building one to go alongside the next system.
Hi Rob, just wondering if you have considered worm juice as a supplement. I notice a lot of guys claim that is all they add.
Have seen folks add it & not sure I would if it's the leachate coming from the base of the farm. That leachate can have some nasty bacteria in it at times.
I'd much prefer to make up a castings tea (like you would a compost one) & add that instead. 👍

What kinds of dangers are there to supplementing iron in other ways? I sometimes will have an iron deficiency in my soil growing beds, which I remedy by simply burying a rusty nail at the base of each plant, and I find that this usually works quite well. Would this same method work for an aquaponics system? Or would the rust in the water be toxic to the fish?
I brought fish friendly iron supplement i wasnt gain enough to try a nail ect lol
Rust from a nail is iron oxide so isn't readily available for plants in aquaponics. Am taking an educated guess & say that there are other organisms in the soil that would be converting that nail into a plant available form. 👍 I know a number of folks that have had the same results as you BTW.
Cheers.
@@RobsAquaponics Thanks!
Thank you
One question about the fish food do you know what it contains is it organic
I'm not aware of any organic certified fish food in Australia. I think there may be one or two available in the US though.
do you have much luck with the marigold? they've never worked for us and we ended up just stop trying to grow carrtots
In the soil yes but haven't really tried them in the aquaponics.
i think your bok choy is doing great. did i see mushrooms in the growbed ?
Hey Shane. Will be picking some tonight for dinner. 😉👍
They are a couple of ceramic ones B bought me for the pot plants upstairs, Through they looked better in the ponic's instead. 😉
Cheers mate.
I love your videos!! I have a quick question. Im having trouble getting my system to show any Nitrate.. my Nitrite are 0 and my ammonia is 0.25 and PH is always in the 8s but that's cause our water is so hard. What can I do??
How old is the system & has it cycled Michael? Would also help to know how many fish & the amount of feed they're getting. 👍
@@RobsAquaponics i started it back in March and I had 30 but some died so im down to 20 I believe they are just gold fish and kio fish im not sure how much to feed
@@michaelcurtis640 The general rule of thumb for most fish used in aquaponics is to feed them only the amount they can consume in a 3-5 min window.
@@RobsAquaponics ok thank you so much!
@@RobsAquaponics twice a day?
Hi Rob hope all is going well. Having a bit of a problem. Got the clay balls. Washed them. But they don't seam to sink. Do I wait for them to get water logged?
It can be a bit of a waiting game. Normally they'll settle down in a few days to a week but have seen some float for up to 2 weeks.
Cheers mate & hope they settle down for you soon.
@@RobsAquaponics thanks mate
Hi Rob, how can i add another growbed to my existing aquaponics system?
That would depend on the layout. If its a split flow like ours, you just need to run the inlet line from the pump & make sure you can reach the sump with the drain. Also make sure that the sump has enough capacity to be able to service the new bed if you're running them as a flood & drain.
Hey mate, just curious as to how you went with the rock minerals. cant seem to find an update on how it went. cheers mate.
I didn't really notice an improvement & didn't get the water tested again sorry mate. I'm now living closer to the lab so hope to be running more test once we get a system or two set up at the new property.
@@RobsAquaponics lovely mate, thanks for the reply :)
If you take out the fish and use worm casting (hydroponic) for a worm tea type would that also feed the plants just as good or would I have to add something to keep the plants healthy? I just got in to super worms (Mario worms) for reptile feed and have had luck with raising them so far.(lot of little ones) I want to use the castings for growing food for my family and the Super worms. Any thoughts on worm casting? (unconventional Dirt) Frack I think its called here in the USA.
Bioponics is a growing system that's been around for a few decades that uses natural inputs to add nutrients into a hydroponic grow system. This site might be better at helping you out than I can 😉

@@RobsAquaponicsThanks I will check it out
I wish I had your brain!!!
🤔 I'm not sure about that Sally. 🤣😉😕
Hope you folks are doing OK. still.
hey rob why did you not use ivas technic or sandponic
I'm into aquaponics for the fish production & the iAVs can't hold as many fish as a system like this as it's explained on Gary's site.
I now folks that are looking at making additions that would mean fish could be increased & might try that at some point.
... is it ok to + the additives in the sump on a split system rather than in the gb ? tia
I prefer to add the pH altering ones to the grow beds so they have some time to disperse through the water & not shock the fish. Generally speaking, I do think it's a good idea to add them into the beds as that's where they are required. 👍
Hope that helps & have a top one.
@@RobsAquaponics then into da GB it will go since it's were required, make sense. Taa
How are you brother, how did the earth life turned out? did you send your water quality out to get tested?
I haven't had the water tested again yet. Have been using a mineralisation tank & am looking to send some water samples off as soon as I get some spare cash. I found that the earth life helped in soil so I think it would help a bit in the aquaponics as well. Only thing I'm not sure of is if the bacteria in the blend would have survived in that environment.
Wouldn't azomite work well in aquaponic?
sir is 6000L/M submersible pump ok for backyard aquaponics? with one gravel bed & two grow bed 1.20 x .85 x.30 beds
It will depend on your fish tank volume, head heights 7 the amount of hose/pipework you have in the system.
I look at a turning the water over in the fish tank AT LEAST 1.5 times an hour through the grow beds/biofilters to begin with then add extra for each bed. I work on aprox 500lph per 300L grow bed then factor in a bit more for the hose/pipework.
Hope that helps some.
thanks Bob for more interesting videos
Hi Sir how are you my name is mansoor I am from Bangladesh I will see your aquaponic video I am very interesting I also doing aquaponics system sir l have a questions is it possible to grow tomato in aquaponics
Many folks do grow tomatoes in aquaponics. They do benefit from higher feed rates & additional potassium for bloom & fruit production.
@@RobsAquaponics
Hi sir thank you very much have a good day
Can we cultivate only within the aquwaponic system without adding external nutrients
Not as I see it you can't.
Some will claim that you just keep adding more feed (namely commercial pellets) & that will be all you need but then you run into issues of having far too many Nitrates which needs to be removed or it could cause issues with the fish.
Like any veggies growing system, there will always be some input needed to look after minor deficiencies.
Cheers.
I subscribe to you and watch your videos on aquwaponic i like. Does the addition of supplement affect the fish and how can it be avoided
@@nimeshaniroshan6843 The supplements don't arm the fish if you use the right ones. Kelp/seaweed is fish friendly & will help with many of the lacking micronutrients as well as potassium.
@@RobsAquaponics thanks
Hi Rob can you help me to do aquaponics in my village in Senegal ( WEST Afrika). I wish to run it with solar ENERGY. When i can buy pump air, water, air stone solar powered. Thank you. For now i am in Germany
I don't have any experience in setting up a solar run system sorry mate. If you're after it for plant production & not the fish it might pay for you to look into iAVs. It's a system that uses sand as the growing medium & as the pump only runs a few times a day it might be a better idea for a solar run system. iavs.info/
Hope that helps some.
How to check the nutrients with the Bluebl
I don't have a bluelab test for nutrients sorry, just pH & water temp. EC isn't an accurate measure of nutrients in aquaponics as not all the nutrients are in salt form.
Have you heard of fulvic acid? It is suposed to do wonders for plants.
Certainly have. Most folks I've seen talking additives like these on natural farming groups will also use humic acids as well. 👍
can't get my ph bellow 8, have hard water, 20 000 L system... any advice?
Best way to lower overall pH in a system with fish is to lower the pH in the top up water. That way you won't harm the fish if you accidently lower it too far.
This clip might give you a few pointers,

Certainly is. 👍
@@RobsAquaponics can we use locally made organic fertilizer for the system
@@RobsAquaponics and what about those calcium hydroxide and pottasium bicarbonate are they safe to fish.?
@@samsunny6483 Depends on what's in it SS. If it's too high in nitrogen or ammonia I wouldn't.
Like to share some pics but not sure how to
UA-cam don't make that easy unfortunately. You could try posting a video here or sharing on our Facebook page facebook.com/Bitsouttheback if you have an account there. 👍
Approx how much was this setup?
A lot of it was picked up cheap 2nd hand or was gifted to us so can't give you an "off the shelf price" sorry mate.
To buy the fish tank, large media bed with a stand, media, plumbing, pumps clay media, stands new & the 2nd hand IBCs & barrels as I have it set up you'd be looking at about $2500.
I got a lot of this gear VERY cheaply 2nd hand or for free. I'm also using a lot of the parts for the 3 or forth time so at a guess I think I've probably spent $400 putting it together as you see it here today. Most of that is filter material & the new pump.
It's FAR cheaper to use the 2nd hand IBC & drums for small backyard systems & would advise anyone starting out to use them before outlaying wads of cash for the "You Beaut " aquaculture tanks & filters.
Hope that helps Gavin.
This is nothing new myself and True aquaponics have been doing this for years. I cover all of these nutrients in depth on the first 16 or so episode of the Growing With Fishes Podcast. Nice to see the rest of the community catching up with the nutrients and getting past fish poo is magic :) I'd remove brightgrows link as over half there advise is flat out wrong and dated for aquaponics a nd leaves out many important elements.
It's a pity you don't label the podcasts with the topics Steve as none show up in a search when you look for nutrient deficiencies. Would be very handy to the community if you could do so & bless us all with your knowledge. 😉
I've never said that fish poo was magic & have said the opposite in a number of clips. I think you may have confused me with your other Aussie mate. 🤔
@@RobsAquaponics I had some one that was going to transcribe them all to make them searchable but he only got about 20 episodes done. Its been a issue with all the content we have now. Nah you never said fish poo is magic but many others do. Keep up with the great educational videos. :) Also alot of cannabis stuff is harder to find because of UA-cam's censorship.
Did you know you looked like THE DICTATOR with your sunnies on? Just saying….
🤣 Will have to take your word for it. Have never seen the movie.
So basically you have to supplement everything 😂...what are the fish doin,???
Everything?
Plants need a lot more than calcium, potassium and iron.
Maybe a quick refresher on plant biology might help you 😉👍
@@RobsAquaponics only supplement u need is iron.. the rest is the fish job
@@NIP28 😆 Mine & many other's plants would beg to disagree. 😉
It all comes down to types & amount of plants, type & amount of fish feed going into the system.
@@RobsAquaponics ok thanks... lemme keep researching
i thought the nutrients you get from the fish is enough for you're plants . aquaponics is expensive hobby.
Just alike any soil bed, they need to be fed constantly as the plants take up whats there.😉
