I am running 3 bulbs. A 10k and an actinic in one flourescent ballast and a 20k in a separate flourescent ballast. It was recommended to me in a different post that I upgrade my lighting. My question is, is this lighting setup enough to get colorful algae growing or will my rocks remain bare (tank started 2 months ago)? I'm willing to accept the fact that I can't keep corals. I can buy a nano tank to keep those. Will my fish only tank come into color with my current lighting?
