I have been using 2 250 watt coralvue 14k MH bulbs on my 100 here at home for 6 months now. I also have 4 VHO blue actinics(sp). I do not see any growth on the corals except for the xenia. The zoos, brain coral etc don't seem to prosper. Water conditions are good. Should I buy 10K bulbs? I hear everybody saying how this is spliting and this has beautiful new growth. What brand of bulb and K shouold I buy.

Thanks

DT
