Saltfinsax Posted November 10, 2009 Share Posted November 10, 2009 What ways have you guy's found to stop the inside of overflow box's from growing all the alge or all the other stuff there. That thing is turning into a Alge scubber filter I think. I clean it and its plugging back up in a couple weeks. Would putting something to stop the light over it stop it?
