I am going to be putting my rocks sand and water in Thursday and would really like some examples. It is a 7 foot long center overflow right in the middle of the room, I posted it last week. It is viewed by the side right when you enter my house so keeping that in mind, I was going to do 4 islands but not sure that is the right route. Figured I would throw it up here and get some feedback before I start. Anyone have any larger tanks with center overflow built, Islands and full reef mode so I can base it off of?
