So I see all these awesome dream tanks from nano to gigantic and alot of them have their rock work up against the sump wall (Fluval, red sea cubes etc) with a bunch of coralline and sometimes greenstars coating the wall as well
Question is : how do you keep that back wall area where the rock connects clean of detritus build up and stuff?
