Why Are My Nitrates Still So High in My Planted Aquarium? How to Fix & Do WAY Less Water Changes.

[@MCorrigan]

Because you're feeding your fish too much and you haven't got enough nitrate consuming plants.

[@treewitch666]

I keep getting nitrate spikes, yet no ammonia I’m so confused

[@Fishtory]

Thats good. It means your bacteria is scaling up when its needed... but im guessing excess food or debris from plants is your culprit...or a dead fish perhaps... or liquid fertalizers can do that also

[@greeneileen]

Oof. I'm looking at my new 80 gallon, in which I've made a little bogwood island with anubias, java ferns and java moss - the slow growers you mentioned. I'm at day 15 of cycle with 14 tetras in it and high nitrites. I think I mentally endowed my liquid quick start bacteria with superpowers and counted on the plants to do the rest. I did have a hygrophilia that melted and there are some floating plants and a couple of pothos starts out the top of the tank, but since it's 8x bigger than the tank I used to have I just wanted it to magically cycle faster. I'm curious whether I'm better off or worse off for being light on gravel. I only bought the smallest bag of the fish store coated kind for a little color and was counting on my canister filter to do the heavy lifting. The fish aren't showing outward signs of stress and I'm feeding lightly/skipping days feeding. I've changed water and added more liquid bacteria but I fear these fish will fall victim to my haste. I appreciate your lists of slow/fast growing plants.

[@Fishtory]

Yeah when the nitrite falls to 0 youll be fully cycled.... then nitrAte will rise and over time you should slowly reduce that with water changes, or plants. Keep up water changes and just add a little Dechlorinator with each change to make the ammonia less toxic...and you should be in the clear soon

[@SamuelDelBuono-fr3oy]

With all this and the lights, how long do you leave your lights on? My lights use to grow algae on the lids bc they were on too long, I use a timer now and I split btw 4 on and 3 off to 4 on then off for the rest of the night. Any suggestions

[@Fishtory]

I tend to turn up my lights full power 6 hours and 50% for the last hour and first. But the stronger the light, and the more fertilizers and or co2 , the more light you can use because the plants will always use the energy before algae... the biggest trick is getting things totally dark when lights are off...because even a 60w incandescent bulb in a room is enough for algae to bloom despite the lights being off

[@l.k.b545]

What is the small floating plant you had with the red root floater it looked to be small round leaves about an 1/8 to 1/4” in diameter

Salvinia minima i would guess.

[@Tarlu17]

This is really helpful! These nuances are so important but easily overlooked. I have a well established tank that is my biggest nitrate producer and I was always stumped as to why until it occurred to me that my light sucked and it was full of slow growing anubias.

Well thanks l, and nice work! Youre quite clever to have figured that out. No one really informs new keepers or any of this stuff early on. Thanks for tuning in

[@RyeTaran]

Just had a scare recently about my nitrates being so out of wack (thankfully the amonia and nitrites were fine), I thought my plants had been handling the nitrates but realized I was wrong and for the exact reason this video points out - I had a severe lack of faster growing plants! (Suffice to say I've sinced purchased some stems and floaters to go along with my ferns, haha!) This video really nicely explains everything and helped to support what I suspected was occuring, especially about keeping the mulm in our gravel substrate tank. Thanks for putting it together!

Check your ammonia and nitrates... and ph (you may have an acidity rise or may have built up too much nitrate in the water and the plants aren't eating it fast enough. ) best of luck...water changes are almost always a good plan, also

[@kerrypitt9789]

Alex this is one of the best videos I've seen on this subject. Most videos are oral presentation or maybe animated, this one was done extremely well. I figured this out my first year of getting back into aquariums and I found my best plants for quickly controlling the Ammonia and Nitrates/ites. I use African Frogbit and some Duckweed. To help keep the aquarium lit, I stretch plastic air line between two bayonet suction cups and then stick them it to the ends so the hose makes its own weir or surface dam to hold the plants on the back half of the tank. This way the lights get through to the plants and still shine on the floaters. I skin off the excess floaters and throw them into the blender for shrimp food.

Running an experiment right now in which I have a lightly planted tank with slight excess of nitrates. I am attempting to reduce nitrates and/or ammonia (should have same results) by adding potassium to incourage nitrate and ammonia uptake rather than adding more plants. Any thoughts?

[@Fishtory]

Adding any ionized salts should offset the toxicity prior to sodium or potassium or magnesium levels are dangers. A 1979 study i found mentioned that as a " fact" as well. So good thinking

[@bletz5732]

@@Fishtory it's been 4 days since I originally added the potassium chloride (ill save you from the details and specs). The aquarium is planted primarily with Christmas moss. I had a good bit of brown (dormant) that has woken and sprouted a quarter to half inch frowns all over. Nitrates and nitrites are 0. Ammonia has consistently grown and Ill have to manual by tomorrow. I assume this is that the nitrifying bacteria can't keep up. I was hoping the moss itself would provide the needed surface area . other than increasing the surface area I'm not sure what else I can do. I'm kind of looking to peak performances so to speak. . Also, do you think it is possible or likely that the solution could have had a negative impact on the bacteria?

[@888y8z]

Hey Alex, Just discovered your channel...wow, I'm hooked!!! In this video you talk about having a strong enough light. I have a Fluval Flex 15 gal aquarium. I'm not sure how powerful the light is compared to yours, but my here's my question: Does light DURATION make up for a weaker light? Will it help my plants to leave my light on for 12-16 hours a day (instead of only 8)?

[@Paul-li9hq]

A normal filter will never be able to deal with nitrates. Ever. What needs to be understood is that the bacteria that feed on ammonia and nitrites are aerobic. There are bacteria that feed on nitrates - but they only survive and work in an anaerobic environment. A normal filter has a regular flow of oxygenated water running through it - so only aerobic bacteria can survive in there. Nitrate removal is only possible via the other methods discussed here. Don't expect your filter to help at all. It is always very useful to actually measure the nitrate levels in your tap water if you're using that for aquarium maintenance and top-ups... My tap water has 20ppm nitrate! So it really doesn't matter how huge my water changes are - even if it's a full 100% - the nitrate level is still only going to drop to 20ppm.

[@JTSBenefitsandBeautyofthePlant]

Just like with Ammonia and nitrites, my nitrates struggle to reach even 5 ppm.....The plants are doing their job perfectly, unlike what a man made filter is capable of.

I definitely also like that method, however I know it's pretty foreign to many folks, and I wanted to cover basic fishkeeping / some fundamentals or intro stuff ...but I do have videos on anaerobic and anoxic bacteria, plenum, under gravel filters / reverse flow versions and also ionic nitrogen containment or mitigation. BSB mini baskets also seem to work fairly well too

[@EuroGupper]

I'm going to use regular potted plant soil and white sand on top of it. The sand substrate will be thick to create bacteria cultures to keep the cycle going. The potted plant soil will be to grow a lot of waterplants I will try to go with 1 water change per 6 months / 12 months. Do you have any advice?

[@csharpe5787]

Put some sort sort of barrier between the soul and the sand, otherwise it'll constantly get churned up on your have mare.

[@EuroGupper]

@C Sharpe A barrier like put the soil in bags or using gravel as a middle layer? I bought a sift to sift out the floating rough parts of the soil if that helps

I think that'll work, you may want to cap the potted plants with some sand too, just so they get the ammonia and nitrates locked in the soil and not the water column

[@obsequiarch7271]

This has been super helpful just in understanding what we need to do once we get our fish in our 75 gallon tank. The main issue we're having though is that the water we're putting in is testing at 0 nitrate, and then within 20 minutes of going in is testing at 20/40. The odd part though - it's empty. All that's in there is the substrate and the few plants. We have lucky bamboo, pothos, anubias, and java ferns. There are all those different plants, but it's still very sparse so I could definitely see it being helpful for us to put more in. I'm just confused as to where the nitrates are coming from at this point without any waste from fish to drive it.

[@Fishtory]

Could be from substrate leaching it...could be in the tap water...could be food and or plant debris, those are kinda the only options beyond fertz and fish. Best of luck!

Yeah, or just a daily fertilizer with nitrates (some of my tanks do that also hehe if you aren't using co2 and EI Dosing for high light plants, and wanting bright reds, purples, pinks and yellows- like a lush green tank...then nitrates up to 30 to 50 ppm are a good thing for plants (as long as you figure out what they require and it doesn't just keep building up every week)

HELP! STUMPED. I have a three month old planted tank. Ammonia 0, Nitrites 0, Nitrates 160+. It has no fish. Occasionally, I will see a wilted leaf and remove it, but most of the plants are growing. My floaters have multiplied so much that they would cover the entire surface it I didn’t corral them. The lights are on 15 hours a day. There is not a spec of algae in the tank. The substrate is gravel. There is no organic material in the tank except the plants. Tap water has minimal nitrates. I do not fertilize the tank, except I broke one root tab in half and buried in under two rooted plants. I can’t figure out where all the nitrates are coming from. Advice? Love your videos 😄

[@Fishtory]

I would assume it has to be root tabs or perhaps the light being on so long is causing the plants to enter their fruiting and flowering growth modes...and if the light was less than 10 hours a day the growth would be vegetative and that's when plants need to use the nitrites, and nutrients to grow and store energy. Also I'd try grabbing a bucket of tap water and bucket of that tanks water....then test both...then let them sit 3 says to a week...and test again...sometimes some cities use chloramine instead of chlorine and it can deteriorate over time into various organic compounds ... but that is fairly unlikely. I hope these suggestions may help a bit! Best of luck to you and have a great weekend

[@2tardi]

Alex, thanks. I hope you feel better. It’s unimaginable to have a tank without plenty of plants. It helps fish as well. I think you may have forgotten two of the most important causes for high nitrates: - tab water - over filtration. I have checked the tab water of acquaintances. They wanted Otocinclus. Problem: their nitrates in the tab water was way too high. Solution: osmosis. Another one complained about algae everywhere and he bought a lot of stuff against it. I had a look at his filter. Problem was he filtered about 10times the tank volume per hour. Water was good. But the water couldn’t stay long enough in the filter (material) to build important bacteria.

[@TheChefmike66]

It hurts my eyes to see an unplanted tank, unless it has inhabitants that don't allow for plants.

[@Fishtory]

Definitely true. ( and I think you mean "tap" water right? Speech to txt or autocorrect messes that up for me too.) The nitrates or ammonia in tap water is pretty rare in most the usa. But certainly does occur sometimes! Well water seems to be the culprit in most folks I've encountered that with (organic debris or leaves break down in their well or water table as organic particulates). Hopefully a Dechlorinator will handle the nitrates or ammonia from that, but yes- nitrates often need RO/(DI) filtration of some sort.

[@otallono]

@@Fishtory father fish has stated that it's impossible for nitrates to even be at high enough level, naturally, to harm anything in the water, it's one of his videos where he had a biologist he was interviewing. Basically saying it would have to be an insanely high number to be harmful.

Sure my friend...I'll add some more plants and write out the ones I mentioned in the video. Equally important is the strength of your light though, to grow those plants. Also, you don't need 0 nitrates... I like most my tanks low (under 20ppm) but some like my guppy tanks can thrive at 50 to 100ppm of nitrates (not ammonia or nitrites however.)

Excellent stuff. However what do you mean the plants are full of nitrated once grown and remove them. What if you trim and replant them. A bit confused here, but I love your channel and info. Australia

[@Fishtory]

Oh so what I mean, is the plants use ammonia, nitrates and nitrites "food"... along with the carbon from co2, and fertilizers/minerals and elements in the water and substrate. So when you trim them, you literally are removing a rearranged form of those nitrogen atoms and it can't die and return as ammonia or nitrogen (same with any nutrients in that plants too... as opposed to leaving it, when it's rotting.)

Does Lucky bamboo remove ammonia fast. I just have the roots dipped in the water, the bulk of the plants (5 stocks) are out of water attached to my filter intake tube with an elastic band. The roots seem to be growing really fast but I don't know if that is as good as the plant growing really fast. Seems like a slow grower to me.

[@Fishtory]

It does work pretty fast, but depends on how much light the bamboo leaves get. Where as pothos vines or prayer plants/peace Lilies can do the same job in low indoor light... it may be worth looking into. Best of luck!

I'm reasonably new to fish keeping, and have had the newest setup running for 8 weeks built a plenum, 3 inch deep gravel and replace the carbon/zeolite filter cartridge with a bag of mixed zeolite and laterite, and modified the filter cartridge to hold the carbon. Last weekend the nitrates dropped from 10ppm to 0 overnight, its now just above 0ppm, 0 ammonia, 0 nitrites, 5-10% water change yesterday (vacuuming the substrate) by sounds of things maybe shouldn't have. Have 8 tetra, 1 Siamese algae eater, 4 Panda Cory, feed minimal flakes 2 times a day and every 2nd night I put 1 pellet of sinking pellet in tank, bout a quarter of tank is planted, has a big piece of bogwood which takes up the bottom of tank, ph is 6, tank is 2ft by 1ft , 15-17 gallon. I heard/read that too low of ph lv and beneficial bacteria will not establish, is this true and is bacteria not able to produce due to zeolite removing some ammonia? Very confused as can't find my answer to why nitrates dropped from 10ppm to 0ppm overnight. All info I can find says that tank is either very new and/or not cycled. Any ideas as to why this happens, is this good or bad?

[@Fishtory]

So you set yourself up a very "hi-tech" tank for a beginner! There's a lot of science (some of which is argued over by 2 camps, as you seem to be grappling with.) So under 6.4 ph or so, the beneficial nitrifying bacteria species that are ubiquitous around the world (Nitrobacter?) (Nitrobacsillus?) Do in fact die. However, there are yeasts at around 5.5-6.2 ph that are able to use Sulphur, iron to metabolize ammonia and there are bacteria that can turn nitrogen into various ammonia compounds that are stable and under the soil cap if they are in zero oxygen environments. Diatomaceous earth, zeolite, and various clays all also have some cool properties of capturing ammonia and or nitrogen related molecules, also ...but the details are very specific to the environmental details and some of it- particularly the yeast that ferments using nitrogen is cutting edge science that I don't know the details of well enough to speak on more than suggesting you Google some scholarly articles on whatever specifics you are interested in. Sorry I'm not more help. But I don't want to lead you astray.. Dr. Novak and his aquarium channel may be of more help also!

Hello Alex. I need your help: I setup a 25litres nanocube by Aqual for shrimps, with floating plants (Salvinia, pystia..), crypts, lot of moss... Some root tabs on sand substrate.. I fill it with Ro and some tap water up to 6.5ph and 4kh. I want neocaridine.. So I need nitrites to zero.. But 2month after I have no2 0.25. So I decide to change the sponge filter provided by aquael together with the tank with a more efficient hob filter (niagara 190)... 1month and a week after, guess how much nitrites I find? 0.25!!!!!! What should I do? I try to raise kh and ph to 7? Could it be a key? What else? I need your expertise and your brain 😢

[@Fishtory]

Well thanks for writing and it sounds like you are on the right track! (Also, I love Italy....when I went to the north of Italy I almost stayed there permanently hahaha. So I'm guessing you may just be reading the test a bit off? Unless it reads 0 when you use the r/o water. But if I were you, I'd pour the RO water into a bucket in the same room... and just let it sit 24 to 48 hours and check what the ph and nitrates are doing. If it's stable...then it's not the water (sometimes r/o water or the remineralizers can cause a bump in nitrates due to free carbon and nutrients that algae or other micro organisms use...and when they die it rises...so you could also try a new remineralizer brand if the water seems fine and 0 nitrates. If that isn't it.... then perhaps adding more light would help, and I assume you change the water by removing a few liters and then adding new RO? Because some people just add more water to what evaporated and then never remove the nitrates.... Oh you know what! I bet the root tabs are doing it! In small tanks they often cause a rise or ammonia/nitrates or nitrites...so you could remove em and do a water change...OR add faster growing hornwart/naja grass/pearl weed/or water lettuce /floating plants and a stronger light to help the plants use up nitrates faster. I bet it's the root tabs if not the water it's self! You could crush a root tab in some Normal water in a bowl or vase and then see a few hours after it dissolves if it caused the nitrates to rise (or ammonia/ammonium or nitrites) Let me know how things are going after you investigate a bit. Best of luck my friend! Have a great Sunday and week ahead. -Alex.

[@dewisalim3320]

Thank you for this video. Very informative. I have a question about the floating plants. It looks like the water surface in one of your tanks is practically covered with duckweed. Is it okay to do that, to have the entire water surface covered with floating plants? I am not worried about the plants under the water, as I have quite strong light and the underwater plants can grow under low lights. I read somewhere that if the entire surface covered by floating plants, it will be harmful for the fish, because it will limit the oxygen exchange, lower the dissolved oxygen in the water. I don’t have duckweed, but I have red root floaters in one tank, another tank has frogbits. They grow so fast, I have to remove some of them every other day, to limit their population to only about 50% of the water surface. I have been worried what if I need to not be at home for two weeks, so no one remove the floating plants and they grow covering the entire surface of my fish tanks :( Please advise 🙏🏻

[@Fishtory]

Yes. So it totally depends on your filtration and your fish species. It's fine if they don't mind low oxygenated water...Stillwater or flooded jungle species- however rainbow fish and some tetras can have a lot of trouble with low o2. Using water lettuce is a better choice if keeping species that like moving water and high o2 content, most definitely! For filtration you either need a filter that splashes water at the surface (even a few inches of open surface area is often enough) otherwise you need a hang off the back, where the swirling of the filter and spillway oxygenates the water by breaking surface tension. Sponge filters are a bad choice (if used alone) when a tank is covered in plants

Thank you so much! This video explains why I have been chasing my tail for the last 4 years. I have a question concerning the gravel substrate. If I discontinue the gravel vacuuming, will there eventually be enough fertilizer in the substrate for me to not have to substitute with root tabs? A second question seems a little off topic but is concerning plants and snails. I have an assortment of snails but am certain the spixie snails are devouring some of my plants, including the frogbit floating plants. Have you known this to be a problem and can you suggest a better choice of floating plant that may not be as vulnerable to the snails? Thanks so much!

[@Fishtory]

So 1. Yes! The gravel will become one giant root tab as long as you feed your fish foods with all the minerals they need. 2. I've found water lettuce and duckweed to be most resistant to snails, they simply can hold onto duckweed hehe. But it can easily take over the tank and be frustrating on its own accord too. Best of luck to you though!

That's just it plants just store the Nitrates they don't remove it. They don't change it or exchange for something else. If the plants die the nitrates are released and plants do just die or get to a point, they can't absorb and more nitrates. It's all about exchange and you can see that with Ammonia being exchanged to Nitrite, then the nitrite is exchanged into Nitrate. The problem with aquariums is the Nitrates are not being exchanged but manually removed or stored in plants. When I say Manually removed, I mean water changes or physically removing the plants. The final exchange to remove Nitrates and be left with Nitrogen Gas that will float up and exit the tank isn't happening. If you are making that exchange it isn't enough or fast enough to keep up with the nitrate generation. What we need is the bacteria that only exists in low or no oxygen environments. That is where Nitrates are converted/exchanged to Nitrogen gas and can break the surface of the tank and actually leave the aquarium. This is what is missing in most aquariums because we strive to keep the water highly oxygenated. So, there are very few zones in the tank that can achieve these conditions.

[@Fishtory]

So for that you need the deep substrate and a plenum or pvc pipe with a hole. Regardless of what mr. Novak says, the exisiting published papers say 6 to 8 inches is the minimal cap depth that it will occur at. So if you have sulphur and elemental iron rich substrate, and somehow osmosis diffusion lets enough gas out as ammonia, you can off gas the nitrate based compounds. The problem is plant roots enjoy ammonia even more than nitrates of nitrites and their roots always bring O2 with them into substrates...as do snail etc. But after a year to 2 years finally it will off gas as nitrous oxide according to studies lookong at German sewer plants (the only peer reviewed scientific research done on aquarium sized tanks). Sadly we need data and replicatable experiments to know if it is possible and or meaningful amounts

[@scotthopkins2235]

@@Fishtory So what you are saying is we can't cultivate that type of bacteria. Because we can't create the conditions and it takes too long to make that exchange to Nitrous gas to be useful. I would be interested in a test not based on sewer treatment. How is this happening in a pond or lake? That is what we need to understand and try to recreate. Lakes and ponds can go months without new water being introduced or old water removed. Next thing I would like to question is all the "Natural" aquariums that owners claim has had NO water changes with just top off for a year or more on KZbin. Is it because we are actually over filtering and generating nitrates? I'm in the starting phase of setting up a 55g and have an idea of how I want to set up my tank. I'm in no hurry to add fish but I'm thinking I can run an experiment creating ammonia once the tank is cycled and see if my theory works. Keep in mind I have no intention of using live plants because I don't like dealing with live plants, I'm not an Aqua farmer and have no interest in going down that rabbit whole. If I can create ammonia and exchange it to nitrates and keep it low or zero without water changes, I'm doing something right. I'm pretty sure that there is something right about Novak's ideas because people are reporting various reduced levels of nitrates using those methods. I'm not saying he is 100% correct but he is on to something. Check out GV Aquariums Australia he tried the BCB baskets and has had a reduction in need for water changes. It's not zero but he is seeing a reduction and that is something to take note of.

if you use a sulfur denitrification generator you can pull the nitrates down to 0 .

The down side is it takes several months to get the bacteria built up in a generator.

I quit fitting against nitrates because my fish are healthy and live long lives with no Side effects. I do my water changes 15% every 2 days consistently and I feed mostly live or frozen foods . Nitrates are what beneficial bacteria can’t break down anymore, what if the live quality food you feed produces less of what bacteria can’t break down. Has anyone thought about that?

[@Fishtory]

Thats a whole lot or water changes and im sure that will keep the fish and tank very happy. People have definitely mentioned that nitrates thought here. Plants like eating ammonia more than nitrates if they have the option In their water column. As for more nitrates in the water, as long as you have appropriate filtration surface area the bacterial colonies will reproduce and grow within 2 to 5 days of spikes in ammonia, nitrites or nitrates. In the substrate there are bacteria that turn nitrates into ammonia/ammonium again as well...so any deep substrate tanks with plants really enjoy that whole process
