Hi Ron, sayin g water peramiters are normal tells us nothing, can you list them for me? also Browing of SPS is an increase in symbiotic algae which usaly means the lighting is low so the coral needs more lighting. as you increase you light the coral will expell algae and get more color.
how deep is the tank and how far are the sps from the surface?
I don't agree with the "corals need fish poop" thing as I had a very low fish load tank (3 in a 90) and a nutrent starved system with extream skimming and my colors were increadable, but every tank has slight differances.
