Since the beginning of my setup ( oct 2011) I noticed this white residue with alot of bubbles keeps forming at the top of the water. After reading and reading I thought it was my seaclone,,, so I just let it by, but I just added a bubble magus ( like someone told me "throw away the paperweight") to the sump and still have the residue...what is the residue? How do I get that out? What's the cause?
