Hey all, I started my tank cycling on Monday and my first tests were about 12 hours after I started it. My results were: 3/16 SG - 1.022 (need a refractometer not trusting the hydrometer) pH - 7.8 ammonia - .25-.5 nitrites - 0 nitrates 0 3/18 SG - 1.022 pH - 7.8 ammonia - .5 nitrites - 2 nitrates - 0 I have about 12 lbs of live rock in there and some used sand that most likely had some dead stuff in it (found hermit shells and a frag in the sand as I washed it clean). I know this probably had plenty of ammonia in it to help get the process started but should I be getting nitrite readings so soon or could I have checked the tube too soon? It was clearly not the light blue the API marine test kit would show if it were at 0 like it was the other day. Anyway, anyone have any thoughts or ideas on the matter?
