Lighting question

I use 2 400w 20KK's on my 75 with no supplemental lighting at all,
everything in the tank does great and are growing like weeds. the only
reason to keep the PC's would be for personal eye pleasure to yourself, but
as you stated your happy with the MH's only, so rip em out.

OK i have a 100 gallon reef setup and have 2 48"130 watt 50/50 power
compacts,I finally decided on 20k bulbs for my dual 250 metal halide setup
for the same aquarium.Do i still need to use the power compacts for
actinic
or can i just use the 20k setup?I really love the 20k bulbs and want to
take
down the PC's
Thanks
