I just purchased a 400 W Reef Fanatic Electronic Ballast (New) from Premium Aquatics $50.00. I plan on using it as my afternoon light (just a few hours a day). I currently have 2- 175Watt MH with 10K XM's and 2- fluorescent actinics. I want decent growth but looks (coral color, crisp white light) seem more important right now. Any suggestion on bulbs would be great help. Personal experience would be greatly appreciated.
