I'm thinking of running the reeflux 400w SE 10k or 14K bulbs. I keep a mixed reef including SPS, LPS, Anemones, and softies. I would also like to add some clams. CoralVue and Icecap are the 2 ballasts I am considering. I currently have 2 1000w sunlight supply MHs. They are to much light for my LPS and softies. Of course the SPS love them but I also enjoy the LPS and softies. Zoos are impossibe to keep even on the bottom of a 24" deep tank with the lights 15" from water surface.
Well there you go. You stated the two options I would choose for a ballast if you want to run Reeflux bulbs. Both are good ballast and highly recommended. Sounds like you will have a very solid plan for lighting your reef. I am a big fan of Reeflux bulbs myself.
