Hello, I have a BC29 that I started cycling 10 days ago. 5lbs LR(one quite live, but the the majority wasn't outwardly vibrant), 25lbs cured dry rock, ~5lbs uncrured dry rock. 20lbs Caribsea agralive LS. Parameters as far as yesterday are: (API master kit) NH3 : 0.25 NO2: 0.00 - 0.05 NO3: Effectively 0.00 (slightly above 0.00 this morning, but very hard to tell) Temp was reduced gradually from 83F to 78.5F over a week. Salinity: ~1.026 pH: ~8.1 Ammonium levels never exceeded 0.25. Nitrates were barely ever elevated above 0.05, visibly. Nitrates never registered above 0.00 until possibly this morning. HOWEVER, I have feather duster in a piece of LR, a star was observed this morning, all trivial, but DIATOMS I believe are blooming. see pics. this rock was pearl white 4 days ago, now there are diatoms beginning to bloom on the sand. Could the cycle really be complete? I feel uneasy about the level of bacteria that could be in there with respect to a WC and then adding livestock. Any suggestions?
