So I put some mopani in my 60 gallon and the fluffy white algae (or fungus) began to grow. I knew that was gonna happen but I didn't think it would also grow on the glass of my tank. My question is, is there an additive that a can pour in to kill all the white stuff? Or at least slow it down? P.s. there are bubbles forming along with the white stuff, is that normal? Are they harmful to my tank?
