Just wondering if anyone out there lets the back wall of their tank "go" while cleaning. I tend to clean the front and sides but not the back. It slowly gets covered with algea but it seems to keep my snails happy. Is it okay to leave the algea in there or will it just spread. It is a combo of a thin layer of brown algea and some purple patches of coraline. Thanks! Lando
