Hello, I'm a new member to this site; but a long time aquariast. I own many tropical tanks presently ranging from 70 gal. to 10 gal. All of them aquascaped. I recently started planning how to build out a very unusual tank. Its dimentions are 48in. x 60in x 18in. Im estimating this tank at 225 gal. I believe I am ready for discus fish, 12 discus is my estimate. Because it will be planted and odessey doesnt make a light that large, Im planning on using a hydroponics sun lamp that rotates. Does anyone see any immediate problems with this? thanks, Copper
