20 gal tank with 25lbs LR, no sand, CPR BAKPAK skimmer, up for two months, finished cycle in about 30 days water test out fine. Two weeks after cycle tank has a large bloom of the little white pods along with cloudy water nothing new was added or done. Problem continues for 2 weeks, I ran a diatom filter, carbon, water change, and no effect. So three days ago I lowered temp from 79.5 to 76 overnight water is clear, problem solved right? NO, water is Cloudy again this morning. Can anyone give me a clue as to what's going on?
