Daniel Posted April 15, 2021 Share Posted April 15, 2021 I have always liked this explanation: https://users.cs.duke.edu/~narten/faq/cycling.html There is debate surrounding how just harmful nitrates are. I am in the camp that they have to get pretty high before I get worried, but not everyone agrees. 3 Link to comment Share on other sites More sharing options...
SWilson Posted April 15, 2021 Share Posted April 15, 2021 I think this video from Aquarium Coop explains it too: and prime time aquatics on YouTube also did a fairly deep dive on it. 4 Link to comment Share on other sites More sharing options...
FlyingFishKeeper Posted April 15, 2021 Share Posted April 15, 2021 Hi, not sure what happens with nitrates, but with nitrites the fish's blood can turn brown, and it prevents the fish from being able to process as much oxygen. I would definitely agree that it takes a LOT of nitrates before it can hurt a fish. 1 Link to comment Share on other sites More sharing options...
