Ok my tank has been set up for three weeks. 55 gal 2 cons. Nitrites read 0 nitrates read less than 5. But have a small amount of ammonia. But I think its a false positive. Using prime with ap. Now I heard fish wont spawn in water that has any trace of ammonia in it. So can I assume my tank is cycled since the convicts laid eggs? And that I am getting a false positive with the prime?
