I like the shimmer of the MH and with the t5 supplementation I can get the colour correct. I know that a halide does about 24" x 24" area so really I'll be looking at two halides now I just have to work on the depth issue which is only 16" worth of water once you take into account the sand bed. So would two 150w not be enough to grow sps anywhere in the tank? I'm not looking for anything large than need fro this setup as if I do upgrade I will get a bigger light. I also run fans on my setup to keep it cool on very hot summer days, my temp ranges from 78 to 81, if I kept the light about 8" or so would that help keep it cooler? The 250w seems to be quite alot of light and typically I've read that 250w halide is for 24" deep tanks or more and 150w are for 18" or less.
