You need evaporation to drive calcium supplementation via topoff if you have stony coral, otherwise not so much. A very good skimmer and active sump could manage oxygenation. If you have a good skimmer, good large sump (30 gal is enough) and no stony coral glass might do fine. Another alternative is patiently cut ceiling lighting grid, cheap, at Lowes. Depending on width (and with creative gluing and careful placement of any weight atop, this could serve.
