Lighting Help

[Madreefer]

I have a 48" Coralife Aqualight Pro with 250W Hamilton DE bulbs and 2 96W PC Actinic. I am happy with the MH bulbs. The PC actinic bulbs need to be replaced. I have enough blue with my MH and was thinking on replacing the actinics with 10000K PC instead. The question is "is there no growth with actinics?" and "any thoughts on how the tank will look?" I also removed the peice of plastic that serves as a lens or cover for the PC's, is that going to cause a problem? And no the bulb will not fall in to the water as the tank is covered. The tank is a 144g half circle witk SPS and LPS. Any feedback will be appreciated.
