Which MH Bulb should I use?

[n2retics]

Ok, well it is the first time for me to replace the bulbs in my MH set-up. I have a 65 gal. tank with a few different types of corals and I have a few fish. The metal halide set-up I have it 2X250 watt 15,000k and 2 65 watt PC's. I found some MH bulbs that are 20,000k would that work for my set up. I did find some other bulbs but it says something about a m80 ballast, i am not quite sure what ballast I have. I do know that there is 2 external ballast for the MH. I could use all the help I can get.
Thanks

I have 2x150w over my 65g. I use 150w Phoenix 14k bulbs and Ive heard very good things about the 250w Phoenix bulbs.
If youre going to use 20k, the Radiums have the best reputation and color that Ive seen.

Radium 20k or Phoenix 14k. Your choice, but I got the radium yesterday and LOVE it!!
