aqua-ed Posted April 15, 2009 Share Posted April 15, 2009 I'm having a fierce outbreak of those tiny little shelled critters that form on glass, rocks, over slows, pumps... it's those tiny curled shell shaped things that look like large pieces of sand until you get closer. they are spreading really fast and scrubbing them off scratches the glass. What are they? what encourages there growth? what gets rid of them? they are almost worse than algae in my book! algae at least wipes off and goes away with water changes.
