I'm having what I think is a phytoplankton bloom in my tank, giving the water a greenish tinge to it. It seems to be pissing off some of my SPS more than anything. Based on what I've read, the easiest fix is to run a UV sterilizer on the tank for a couple of days - anyone have any other recommendations? From what I've read, GFO, water changes, and carbon will have little impact if this is indeed a phytoplankton bloom, which I suspect it is.
