Hi guys, I am at the beginning of the 4th week of my fishless cycle, so far my ammonia is close to zero, but nitrite (> 2 PPM) and nitrate (> 20) is very high, the API test kit is just very hard to tell after you get to the higher levels.
Should I continue to to add fish food to my aquarium as source of ammonia? I also have alot of melting plants in the tank as they adjust. I think I have a good amont of BB for consuming the ammonia, but the nitrite BB is still developing and cannot catch up with it. I know I need some form of ammonia to keep the BB alive but how much should I add? Also, do I need to do some water change now to lower the nitrate and maybe even nitrite level?
Also, I heard of a 3rd kind of BB that can consume nitrate and turn it into nitrogen gas in the live rocks for saltwater aquarium, could this kind of BB exist in freshwater as well?
