I ended up using a revolution skimmer. That was the only skimmer that would work in the deep water level I have in the sump, also had a tight fit and just fit perfectly. As for the tanks design I saw the tile design at MACNA Atlanta last year. The company was Reef Aquaria Design (RAD). Check them out on the internet, they were a great company to deal with. The whole design was handled by the person JR. Great company to deal with. Their phone number is 954-596-2800
