I really like the blue color of my tank. I am running 4 actinic PC's with 2 10 k bulbs. I am switching/buying tonite dual 250 watt metal halides for my 150. This with be with halides only. My question is shoudl I go with 20 k or 15k bulbs to achieve the blue color with no additional lighting. Also will I be able to grow with a 20 k bulb?

Well 20K will be fine by themselves but your growth will suffer. The 15k will give more growth but not as blue. If you want growth stick with the 10k
