I have 2 reefbreeders 16" controllable units over my 110G mixed reef. The guy I buy my coral off of uses T5 lighting and it seems as if the coral colors pop and are magnificent looking. I get the coral, bring it home and it never looks like it did at his place. The color just isn't as good. Is this due to LEDs? Are LEDs that much different then T5s? Any recommendations to help me out?
