Unfortunately, as quickly as things seemed to be going very well, they have declined. About a week ago I switched my pump out for the stock pump which offers about 33% less output. Still 100gph. I also missed a few days of feeding and nitrates climbed to about 16ppm and Po4 stayed at 0 which I thought was odd. My SPS began to pale and bleach and I can’t figure out why. I also noticed my flatworm population increasing but they appear to be harmless. My first step has been to blow the diatoms off the affected corals and feed a little more while stopping my dosage of acropower and dry phyto. Doing this in an attempt to raise Po4 and hopefully get my corals back to normal.
