There's a white growth on the bottom of my Palythoa (looks like a very large Qtip head that is white and a little fuzzy). In general, the Palythoa has not been looking so well recently and I don't know if this is related. The water quality all seems good at 1.26SG, no nitrites, no nitrates, no ammonia, and Ph of 8.2. Curious if anyone has seen something like this and if so, what if anything should be done?
