I have a tank that has been running since mid-July. I chose the fishless cycling method, adding pure ammonia. It took two months for nitrites to show up. Now they have… and I want them to leave! It has been a month now since the nitrites showed up, and i have no signs of nitrates, and no sign of the nitrites going down. I was adding stress-zyme to try to “speed bacterial growth,” but stopped spending the money. One day I got a reading of zero nitrites but I think it was a faulty test for whatever reason, I got the same readings as before the next day, but I had algae growth so I thought it was okay. (I use API’s master kit).I added several more plants and three tiger barbs anyways (like an idiot). They have been in there for a week and a half now, and are doing ok, but showing signs of nitrite poisoning. Nitrites are still high with no nitrates. It’s been over a month. What can I do? Thanks!
