I just finished testing the water in all 4 of my tanks and they all showed a slightly elevated amount of Amonia about .1 and 0 Nitrite & 0 Nitrate. What would cause a small of Ammonia but no Nitrate? Do I need better filtration or more WC's?
All 4 tanks have been established for just under a year. I have not changed anything recently. ABout 2 weeks ago all 4 tanks had no Ammonia and about 30 Nitrates. The only thing that I have done during that time was a water change
