PC bulbs

[kevjtomy]

I know this topic comes up from time to time, but...
I have a 4x96 PC light system. I currently have 2 10,000K and 2 7100K. Within a few months it will be time for new bulbs. What combination of bulbs would give me more of a blue color? Would like a little more flourescance(sp?) from polyps etc.. Any suggestions? I wanted to add a NO actinic to the PC's, but I have no room for any more bulbs on my tank...

I think your current combination is blue enough. Unless your water is really yellow or something. You can try the 50/50 smart lamps, maybe that will give you more blue. Not sure that is good for the health of your corals though. But I would definitely stay away from "true" pc, nice for dusk and dawn, but not intense enough to balance out the 10kk bulb for a nice blue.
