hopeful1 Posted July 31, 2021 Share Posted July 31, 2021 What is the best nitrate test product in your opinion? One of the solutions mentioned to deal with nitrate is to add a additive with pre-developed bacteria. Some of the videos speak of adding the bacteria to a tank which is unpopulated? Is it possible to add one of these additives to a tank without harming fish? Do you have a favorite brand? I have done so many water changes that my nitrites are nothing, but my nitrates are high. It is a 40 gallon tank with 10 fish now, so it could create nitrites quickly. The aquarium is planted a bit with a canister filter. Link to comment Share on other sites More sharing options...
