I was considering two of the aqua panels as well, but for the same amount of money as two aqua panels you can get the aqua ufo, which is 20w more than two aqua panels. Plus rob at red c did some research on the aqua panels and the manufacturer doesn't recommend the use of aqua panels for growing coral, although I think they would grow coral fine, but if u r going to spend the same amount of money I would go with the aqua ufo.
