Black Algae?
I seem to have black/brown patches on the side walls. The water itself is crystal clear. I see these patches for some time now and slamming doesn't seem to help. I'm not sure if its black algae or the surface itself is damaged. Attached some pics here of the walls. Any thoughts on how...- bobmano
