I have the original 15k(not 14k like everyone else) bulbs that came with the odesea 250 metal halide fixture. It also has 4 65w actinics and a bunch of moon lights. I had to replace one ballast. I did so with an icecap electronic ballast. It is great I am going to replace the other ballast as well with the same one. I do think there may be a problem. I think the new better ballast (sold as a 250w but rated at 265w) is over powering the cheap bulb. It sort of has a yellow orangish tint to it. None of the animals seem to dislike it but I get a wierd algae bloom almost like green dust on the glass. Its only on the side with the better ballast. This leads me to my question. I was going to get the other new ballast and put 20k bulbs in it but would that be too blue for my corals? They are stonies- acros, galaxea, monti, some other branching stonies, bta, brains, dersa clams, some other misc. Should I just get better 14k bulbs? This is all in an 80 gal. All advice would be appreciated. Thanks a bunch.
