I'm in the 9th day of cycling a 55 gal tank with 5 small danios, and I'm not sure if my tank is actually cycling or not. So far, the fish are doing great, and my tank looks great as well. However, for some reason my ammonia registers at .5 (although this might be skewed since I'm using Prime), but my nitrites continue to be at 0. Also, I haven't experienced any clouding of the tank, which apparently is to be expected when cycling. BTW, I'm using a new emperor 400 with 2 filters. Does this sound normal to you? Should I perhaps pull out the 2 disposable filters until the tank cycles? (perhaps the filters are keeping ammonia levels too low for bacteria to form) Any advice? Thanks.
