I've had issues with flow moving sand around, so I got some coarser sand (Seachem pearl beach, I already have Seacham Meridian in the tank). I've added this to the parts that always go bald, and so far, so good. I'm thinking of adding an additional powerhead, because one corner especially has very little flow.
I'm also thinking of adding a powerhead to the sump, and a container of rock. Currently I have rock rubble in a mesh bag, but I think popping it in a crate would be heaps easier for cleaning. Is there any kind of plastic I should be really avoiding?
