I have one Hydra above a frag tank. 33 gallons The densions are: L 36 1/4 x W 18 1/4 x H 12 7/8 Not getting great growth with the corals. I have the light 10 inches above the water. Whites 25% UV/Blues/violets 75% Reds 10% Green 20%. Any advise or if you have a similar setup please list your paramaters. Thanks!
