I have Caroline algae growing on my black back glass (its not glass, but the back panel separating the sump and the tank) and its not easy to scrap off. When it grows on the glass its no problem, but the back panel poses a particular problem regarding the cleaning of it. It has a rough coating on it which makes the Caroline algae particularly hard to scrap off.
Is there any way to make this easier to clean?
