I've researched this topic a lot. I've been on the phone and talking to people. I used to run a 36 inch column on top of a 56 gallon column and hated the fact that it was literally hanging over two inches on each side. Got a 24" they told me it would fit and low and lo and behold it didn't. I had to get a glass cover for it but there is some light. I LOVE wave spots. My corals too. But the side is killing me. So I'm going to build a canopy and hang up new ones with some wave LEDs. When one door closes another opens, I'll post a photo later.
