Hey all, I want to put out a feeler of what people think about coral walls like zoas or whatever taking over a back wall in an aio tank, aside from making sure the returns stay clear. This is my vision for my 7 gallon Waterbox I’ll be starting here in a few weeks. Obviously I have a lot of time before I add animals, but I want to have a game plan and see it through before I add my first coral. Thanks all for your input.
