I have a 55 gallon fowlr, protein skimmer seaclone 100, fluval 305 , 2 airstones, and I have these little micro bubbles coming out of the skimmer into the tank. I didn't have them in the beginning now I do, I also have some coming out of the discharge of my fluval 305, I don't like them , I like my tank clear. Help with any suggestions please.
