Well, I finally got my Corallife Powercompacts ( 48 inch 2x65 10,000k and 2x65 blue actinics) which is in my canopy on my 90 gal tank. I was wondering how long and in which order should I use the lights. I was thinking on running my blue actinics in the morning for about 2 hours by themselves, then having my 10,000k's come on for about 8 hours (with the blue actinics) and then shutting off the 10,000k's and just letting the blue actinics run for another 2 hours by themselves. Just a thought...What's your opinions. Oh, and by the way, I have 110 lbs of live fiji rock and no corals yet, but soon i'll add some gradually. Thanks.
