I dosed AlgaeFix a few times in my 50 with no obvious ill effects. Tonight, I went poking around to make sure all was well. It was, with one exception. One of my moss balls was looking like it was filtering all the dirt in the tank. I picked it up and found that there were brown spots on it and the bottom was almost all brown. Probably should have taken them out before dosing.
