Marden Posted December 20, 2023 Share Posted December 20, 2023 Having a hard time finding an answer to this one. All the answers have to do with cycling an aquarium. I am curious how long it takes a fully cycled tank's bacteria to convert ammonia to nitrate? Link to comment Share on other sites More sharing options...
govsfabshop Posted December 20, 2023 Share Posted December 20, 2023 I've always heard 2ppm should be converted in 24hrs. 1 Link to comment Share on other sites More sharing options...
Katherine Posted December 20, 2023 Share Posted December 20, 2023 (edited) My tap has .5ppm ammonia and I've had a newly filled tank with an established filter convert it all in less than 12 hours. Edited December 21, 2023 by Katherine Link to comment Share on other sites More sharing options...
AllFishNoBrakes Posted December 20, 2023 Share Posted December 20, 2023 If the tank is fully cycled it should happen fast enough that you can’t detect it. Essentially, that’s how you know a tank is cycled. I know my tanks produce ammonia on a daily basis, but I can’t pick it up on a test, because it’s being converted to nitrite and then nitrate at a rate fast enough that I can only pick up nitrates. 3 Link to comment Share on other sites More sharing options...
Galabar Posted December 21, 2023 Share Posted December 21, 2023 This is a hard one to answer. It would depend on (a) the biological capacity of your filter and (b) the amount of ammonia it has been processing (although, once established, nitrifying bacteria can multiply rapidly).
