Hi guys. I'm trying to decide on an aquascape for my first tank. The dimensions of my tank are 6'x2'x2'. The board that the aquascape is on is 5'x2', its the the stand I built for my water storage tanks. In one of the photos, I circled a support rock that I will probably remove and just use glue and mortar to make the shelf hold. Looking for any advice. Not sure if there is too much rock here for flow. The highest peak of the rock is about 14". My garage is a mess atm.
