I was curious about Metal Halides. I have PC's blue/white and also 3 1watt lunar lights. I read alot on metal halides and have seen a nice unit from Corallife that is about $700 w/ lunar lights. It looks like a nice unit but pricey. I was wondering do all metal halides need to be over open water? I have a canopy 55gal. I see retro kits but noticed that metal halides have just the white bulb and not the blue lights like the PC. are the blue bulbs necessary in Metal halides? Also do they go on timers like the PC does? Thanks
