I have a 220 gallon barebottom fowlr heavily stocked .I used to have 20ppm nitrates quite often. I decided to add biopelets in my sump in a media bag . Surprisingly after 3-4 days my nitrates are zero . I tested using 3 diff tests . I don't have any algae in my tank. What's the side effect of zero nitrates?
