So I just started noticing this around a few of my coral frags. I thought it was diatoms at first but after I left the lights off for a day I noticed no change. Its just growing in a few spots but looks like it has potential to be extreme. What should be my next step? My phosphate never is really that high but I'm going to start GFO tomorrow, thoughts? Included with the algae problem pictures, a pic of my random purple acro that is growing nice is also shown
