    I have been keeping a tank with water changes every two to three months. Not because I did not care about nitrate, it had been because I did not know what is nitrate. I had been handed over a tank and I have been slowly picking up the knowledges regarding fish keeping. When most of KZread videos talk about a weekly water change to keep the nitrate down, I have been sceptical regarding the nitrate level. This video is just in time to give me more confidence.

    I know you made the video 2 years ago, but THANK YOU. I have a 100 gallon tank and have had a tank for over 25 years. At the beginning, like everyone else, I tested the water constantly. I added chemicals dependent on what the test strips were showing me. I came to believe that I was wasting my time and not enjoying my tank. I still do testing sometimes but I now go by what I see. If my equipment is large enough for the tank... if my plants are living... if my fish are living... then my tank is healthy. Once again, common sense conquers all. Thanks again for the video and putting the fun back in the hobby.

    I couldn't agree more. A lot of the dogma is created by the industry itself in order to sell products. At different times in my life, due to circumstances like working 60 to 70 hrs a week for months on end, I have had my aquariums fall to despicable filthiness. I am sure the nitrate levels were very high. I was too tired to check them. (This was the life of a factory worker.) The fish did fine. I am not advocating that no maintenance is a good thing but many of the things we are told are untrue. Also, I think there are many in the hobby that due to their personality are prone to liking doing water changes. I have noticed that these people often think things have to be exact and squeaky clean. I think water changes are good within reason but I prefer to do it less often and actually my approach is lots of plants. I like growing seaweed and also use aquaponics with many terrestrial plants growing on top of my tank. Plants are aesthetic in and around your tank and the fish feel more at home with a jungle growing all around them both inside and outside the tank. I also think most of us in the hobby have a love of science and enjoy tinkering with our tanks, testing water perimeters, and generally enjoy working on our tanks. It is just that some of us are more zealous than others in our approach. Science is full of dogmas that are easy to get caught up in. Many years ago it was thought that the more aged the water was the better it was for your fish. Ideas change with time. In the hobby, we tend to want our aquariums to be crystal clear clean. We vacuum, we do water changes and think that because it is squeaky clean it is healthy. Some are now saying tannin water from leave dubree is more healthy for your fish. This seems to be going back to the idea that to the idea of aged water being good. I think that in the end a lot of it depends on the species of fish you are keeping in your tank as to what kind of water conditions are needed. If you think about it many fish live in dirty muddy rivers where the water is never crystal clear.

    Well this video explains so much. My father got me in the hobby as a kid. I got my 1st tank at 12. Dad showed me the ropes and I did all the maintenance myself. I am 52 now and back then we didn't know what nitrates or nitrites were. All my dad was concerned with was ph. He was diligent about keeping ph at a healthy level for the fish. We only changed the water about once a month and our fish thrived. Well I got out of the hobby for about 12 years and recently got back in it and learned about nitrates, nitrite and ammonia, stuff my dad never knew to teach me about. I have done more water changes in a month than I did in 2 years back in the day. This video explains why my fish didn't die back then. So, I am going to ween my cichlids off of twice a week water changes and eventually get it to bi weekly or monthly and just do like dad did and maintain the ph. Sir you just gained a new subscriber. Thank you so much! My mbunas and my American cichlids thank you as well since I won't be bothering them with frequent water changes anymore lol. I have 2 tanks. My mbuna are in a 75 gallon. I have a 55 gallon with 2 Electric blue Acara, a red spotted Severum, an albino chocolate pleco, a juvenile king Kong parrot, 2 blood parrots, a juvenile Oscar, and a red tail shark. The Oscar will eventually go in my son's 75 gallon tank since it's his fish. It isn't big enough yet to make that jump

    The article you linked to made an intriguing point. The quickest way to lower nitrate is large water changes, large amount of water changes-large amount of water conditioners sold to people. If freshwater aquarium keepers stop spazzing out about nitrate and stop running through bottle after bottle of water conditioners, the industry would lose tens of millions of dollars a year on lost water conditioner sales. It appears that for most fish, ppm concentration can be in the hundreds while taking off low percentage points off fish growth rate and life span that no keeper would ever really notice. Would you notice if you had a red tail shark for instance that grew 1 percent slower and lived 1 percent shorter? That's what would happen at nitrate PPM over 130, lol.

    I’ve been driving myself INSANE trying to get the nitrates down in my new tank for nearly a month now, I was getting a reading of 40-50ppm even just a day after doing a 50% water change. It’s funny, I’m coming back to this hobby after a 5 year hiatus and I never even tested for nitrates back then and yet I could count the number of fish that died in my care on one hand (over nearly 10 years of maintaining 3 separate tanks). This video was very reassuring, and thanks for sharing the article too. Keep up the great content!

    Thank goodness for this. There is so much contradictory information out there, I’m a Newby to this and have just cycled my first tank and brought a little guy home and of course the readings all changed because when I put him in, he changed everything and I had myself in such a panic was probably stressing him out more by doing all of these changes etc trying to get everything just perfect (as well as stressing myself out). My nitrate level is nothing to be concerned about but for some reason I was convinced it had to be lower until one person with common sense on a betta forum sent me some valuable information and said to leave it rather than constantly changing the tank environment. My little guy finally starting to settle in coming up to the surface to be fed while I’ve been worrying myself sick about water levels! now I might get him a couple of nice new plants

    To participate in your study (Nitrate NO3) here are some figures validated in France: remember :1 PPM corresponds to 1 part per million, or 1 mg/liter of water. To give you an example: no centenarian in France has consumed between the age of 1 and the age of 60 more than 8 mg/Liter of NO3 in the water. Humans Water suppliers can legally go up to 50mg of NO3 per liter in France. 800 ppm is letal for Guppies, 800 ppm = 800mg/Liter of water!The same amount for human beings! During the world championship of guppies, a winner has never won with a breeding having water with more than 8 mg/liter of NO3.

  • @ragnos28

    I think I knew for a long time that nitrate, as in NO3, is the non/less toxic byproduct of the Ammonia procesing. The toxic one is the nitrogen dioxide as in NO2 (or nitrites), to the point that, the safe level of nitrites in an aquarium, is considered to be between 0 and 0.2 ppm (ml/g). I keep doing my 25% weekly water changes, mostly because fish seem to like it and whatever my fish like, I also like 😁The strips tests show 0 NO2 and 100 ppm NO3, before the water change. Edit: about your discution about the "red", the strip tests from JBL (what we use in Europe/my country) shows "red" for 500 ppm NO3.

    I’ve kept tropical fish for about a decade now. In my experience, nitrates, as measured by commonly available commercial tests, are emphatically not harmful to fish at the levels the typical aquarist is likely to see in his or her tank. It is a myth, one of several that afflict our hobby.

I'm just getting back into the hobby now that I'm retired so I was very concerned because my tap water is about 20-40 ppm. The pet store suggested using filtered water so I tested that. Still at 20-40 ppm. So I used RO water to do a 50% water change. But I was concerned about my live plants. This has set my fears to rest!!!! Thank you again!!!

    Thanks for this video. I've come to the same conclusion. I use to stress when nitrates got over 20 ppm, but unless one severely under stocks and under feeds, it's hard to keep nitrates super low in an established moderately stocked tank. I worry more about dropping pH. I just do weekly or biweekly water changes and stop stressing. With my DSB tanks, nitrates still show up but level off at 40 ppm at the 2 week mark. I'm happy with nitrates at that level.

    I do seem to experience the same thing .. About nitrates..i prefer natural planted tanks and less water change tanks And sometimes even with 150ppm nitrates fish and frys are fine.. I think it's more important that water parameters remain stable rather than concentrating on absolute values.same thing is said by father fish too.. Having said that, it is also true, that nitrate does get absorbed via the gills of the fish and it does convert the haemoglobin to methaemoglobin which reduces the oxygen carrying capacity of the fish..so yes, insane levels do need to be controlled.. One question comes to mind though.. Does excess nitrates hamper plant growth ? Also, of nitrates are not much of an issue, what's the point of deep substrate or anpxic filtration?

    Ive watched and read endless stuff now and today i watched this video, i read the article attached in description and its all compelling for me, i think we've all been duped into the tap safe marketing scam, they must know but they'll loose profit and trust in consumers should they admit its all a con. Trouble is i love my fish to much to take the risk by not doing a water change at least once a week, im 100% certain nitrate is not as toxic as they make out but i guess its just a symptom of fear all produced by marketing, however i don't buy tap safe/ dechlorinators i let the chlorine disperse into the air by allowing the water to stand 48hrs to a week in a tub and all minerals remain as dechlorinators state they remove heavy metals but do not state what metals, phosphorus, magnesium and iron are beneficial for plants so if they remove these minerals i.e heavy metals then the dechlorinators really just add dead useless water to your aquarium. Plus they don't tell you that chloride/chloramine turns into ammonia once treated with dechlorinators, who needs extra ammonia. Anyway nitrate is plant food so its all a natural cycle we're interfering with and people wonder why their plants wont grow, don't worry there's fertiliser for that and liquid carbon, all with added need for 25% to 50% water changes to detoxify the treatments at the end of every week. Really its ridiculous the amount of interfering we do with nature thanks to the marking ploys. Personally i prefer to do 15% water change once a week using the slow natural evaporation of chlorine because im adding beneficial minerals for my plants and may well be beneficial for the fish too, everyone says how healthy my aquarium looks, plants and fish all thriving so im confident im doing something right and im not funding these scam marketing industries, nature is caring for itself and thats a real ecosystem.

    I agree. I think nitrate levels have been blamed for potential illnesses instead of the real culprit. As nitrates rise between water changes, so could bacterial concentrations. I think that's the real issue. If you have a healthy, clean tank, then things will be fine. If you don't have adequate filtration to breakdown waste, then potentially harmful bacteria will use it to flourish. Nitrate levels will end up spiking at the same time potentially harmful bacteria does. That's something we can't real test for at home but makes a lot of sense to me.

    then this happened ""A review of physiological effects and known toxicity thresholds of nitrate for aquatic organisms is provided by Camargo et al. (2005). Physiological effects of nitrate to fish and other aquatic species include methemoglobinemia (Grabda et al., 1974, Cheng and Chen, 2002, Tilak et al., 2007), decreased immune response and osmoregulatory function (Hrubec et al., 1996, Hrubec et al., 1997), and endocrine system disruption and effects on reproductive maturation (Guillette and Edwards, 2005, Hamlin, 2007, Hamlin et al., 2008, Good and Davidson, 2016). In some cases, elevated nitrate-nitrogen (NO3-N) levels have been found to cause fish mortality. Several lethal toxicity studies have been conducted with salmonids; namely, Westin (1974) reported 96-h LC50 concentrations of approximately 1355 and 1310 mg/L NO3-N for rainbow trout Oncorhynchus mykiss and Chinook salmon Oncorhynchus tshawytscha fingerlings, respectively. Kincheloe et al. (1979) observed significant mortality in larval cutthroat trout Oncorhynchus clarkii henshawi, Chinook salmon, and rainbow trout at NO3-N concentrations of only 2.3-7.6 mg/L, demonstrating a possible influence of salmonid life stage on nitrate toxicity. In contrast, Freitag et al. (2016) found no difference in survival of Atlantic salmon embryos exposed to mean NO3-N levels of 4 or 93 mg/L. The response difference of juvenile salmonids to NO3-N between these studies is surprising, but could be related to dissimilar water quality, such as hardness or sodium concentration, or the species under evaluation. Recently, there is increasing evidence that elevated nitrate can chronically impact the general health and performance of fish cultured in RAS. Davidson et al. (2014) reported that rainbow trout exposed to 80-100 mg/L NO3-N for three months demonstrated chronic health and welfare impacts including an increase in abnormal swimming behavior, increased swimming speeds, and mildly reduced survival. In addition, the growth of juvenile turbot Psetta maxima was negatively impacted at NO3-N concentrations ≥ 125 mg/L, and health and feed efficiency was reduced at ≥250 mg/L (Van Bussel et al., 2012). Schram et al. (2014) also found that feed intake and growth rates of African catfish Clarias gariepinus were significantly reduced during 42-day exposure to 379 mg/L NO3-N and therefore recommended an upper threshold of 140 mg/L NO3-N for safe culture of this species. Research assessing the effect of nitrate on Atlantic salmon is limited. Freitag et al. (2015) evaluated the endocrine disrupting potential of NO3-N levels (5.3, 10.3, and 101.8 mg/L) in pre-smolt Atlantic salmon (102 g to begin). Plasma testosterone was significantly greater in salmon exposed to 10.3 mg/L NO3-N compared to 5.3 and 101.8 mg/L NO3-N; however, growth was unaffected. The authors concluded that Atlantic salmon may be a suitable species for RAS production based on the general lack of effect of NO3-N on growth and most endocrine responses at concentrations up to 101.8 mg/L. The Freitag et al. (2015) study was a short-term trial lasting 27 days and only investigated the effects of nitrate on pre-smolt Atlantic salmon. Long-term research evaluating the effect of nitrate concentrations on Atlantic salmon is lacking, and a safe threshold for chronic exposure has not been fully established.""

    Studies on ocean salmon and trout aren't really relevant to freshwater fish. Additionally all of the numbers in your comment need to be multiplied by 4.4 to match what the home aquarium tests measure. So yeah most of those numbers are in the hundreds and thousands.

    Well said nitrate and the fear associated with it . just plays in to API’s and other test kit providers hands . They have made millions and continue to of the back of that Red colour. They ain’t getting another £ or $ of me that’s for sure . The more you hold the test tube up to the light figuring out the shade of Red, the more gullible you are to doing a re test using more of the product and ultimately parting with more cash😜 I’ve kept fish for 45 years and have never lost a fish to nitrate and I can honesty say I’ve probably tested nitrate about 10 times in 45 years and that was out of curiosity more than anything. The best thing to do is get a maintenance and water change routine in place that works and stick to it as best you can . That’s my tip

    1000% dead on .... so many people scareing people saying its gotta be below 20ppm.... most tap water contain 20ppm one thing thats taught me to ignore nitrates is my shrimp tank (fully planted) has 40/60ppm at the end of the week (time for water chance) is the same as my goldfish tank 3 goldfish with some slow growing plant) at the end of the week ?? .... using api test kit ......so now i just do a weekly water change with out worrying about the nitrates if any thinking if wrong then i fully test but once again hardly worried about nitrates.... just make sure 0 ammonia and 0 nitrites think you for stepping out of you tube sheep line and saying what the real fish keeps think about nitrates

    Nice job trying to tell them though. I see the same in many facebook groups; if you don't comply with what the fish police admins say, you're considered bad for the hobby / bad for their ego and you will probably get banned. :'-) Many can't see past the limits of their "aquarium gospel"... It extends to the care of other animals as well. For example recently, in a musk turtle group, I questioned someone's insistence on those turtles (originating in temperate and subtropical areas) having to live at PRECISELY tropical temperature X... and I questioned some other seemingly arbitrary pieces of information shared there that I found odd. Well, that was my last exchange there lol. I was first muted, and when I dared send a message about it to some mod, I was just banned. Some communities are weird like that. They don't appreciate logic and common sense.
