Ok, so I think my tank is or at least should be well established by now. Did and do all the right things but somehow the ammonia keeps persisting at 0.25 ppm no matter what. That's the results API test gives every single time. Nitrites 0 Nitrates below 5.0 ppm Did regular water changes, cleaned gravel, treated with Prime and Stability. Nothing. It won't go down to 0. It doesn't rise above 0.25 ppm but won't go down either. WHY ??? Tank 10 gl Load: 1 betta, 6 small rasboras, 2 snails, well planted. Note: tested straight tap water too. No ammonia there, so I'm not adding any with the water changes. Please help. Can it be I get false readings ?
