I am looking at a used reef ready 72g bowfront. It has an ice cap 430 lighting system with 3 48" bulbs. I think it was one actinic and 2 white (can't remember what those are called). Is this a good quality lighting system? This will be fish-only with a bunch of live rock, but I want to make sure I get a bunch of coraline algae growth as well as other algae for misc. critters.
