Im upgrading from 120 to 150 gallon new aquarium for my birthday!! We are building stand from 2 inch angle iron coated well with rubberized paint based on last stand I had. The bottom of tank will sit on plywood across to form solid base. Im also getting 10mm eva foam for underneath tank. I did confirm with sc aquarium and was told that would be a good base. When hubby gets the stand welded will show pics. I purchasing it predrilled in back for 16 inch synergy overflow but have not heard good things about thst box so am having a modular marine 16 inch box custom made to fit the holes. Any thoughts or experiences you may have had so far about what I have proposed so far?
