Lighting question

[chewieee]

I have a 4X65W Coralife PC fixture that has 2 10k and 2 actnic would it be benifical to change that to 4 10k bulbs and use an old 2 bulb flouresant fixture to run actnic ?

What kinds of corals are you planning on keeping or do you currently have? 10K Bulbs will promote more coral growth but with a PC fixture you are limited to what kinds of corals you keep. Any high light SPS corals would have to be kept high in the tank. If you are going for more soft corals and some LPS then the setup you have now will work just fine. One thing to keep in mind is that you will need to replace those bulbs every 6-8 months to keep nasty algae from becoming a problem.
