If you are going with PC's I would strongly recommend ay least looking into T-5's instead, much more light gets to your corals with T-5's(and good reflectors). Either that or get a 2nd halide and supplement with t-5, even better. T-5's run much cooler and use less energy though (than MH). Just a thought for you to kick around. Hope all goes well.
I also have some frags if interested...frogspawn, xenia, various softies/ shooms.
