I use xm, radium and Coral Vue 20 k bulbs. All three work fine.
I'm getting a lot of questions on the epoxy resin that coats the great stuff styrofoam. Any brand of resin is fine, the important thing is that it does NOT HAVE MOLD INHIBITORS. I used the first brand I could grab from my local home depot. The stuff needs to cure for a week or more before you put it into a full fledged reef. I actually let mine cure in fresh water and tested it with goldfish. When it stopped killing them I figured it was cured. Then I dumped all of that water and mixed in saltwater. The structures are extremely boyount. Mine are siliconed to the bottom and weighed down with live rock. Don't rush the curing process for the epoxy resin this does take a while. The great stuff on the other hand was ready in 24-48 hours. The resin more like two weeks
