I'm setting up a 20g high frag tank. I'm going to use my old Coralife PC light. It's got 2 bulbs right now. One is 65w True Actinic and the other is 65w 10,000K.

I don't care WHAT this tank looks like. It's not meant to be pleasing to the eyes. I want maximum coral growth. I am planning to grow zoas, mushrooms, SPS and LPS. No softies or anenomes.

I think I should go ahead and keep the 10K light. But should I keep the actinic too? Do these corals NEED that spectrum to grow, or is that just for our eyes to make it look pretty? It would be great if I could just use what I got, but I'm not sure if they need that blue spectrum from the actinic. If I could get better growth from another 10K or even a 6500K, then I'd dump the actinic and go with one of the lower K light.

OR:
Keep the actinic and dump the 10K for a 6500K? Or 8000K?

Thanks
