I have a zoas, palys, two ocellaris, and a pj cardinal in my aquarium and wondering if I should have more blue lights in the 420-480 nm range for the zoas and palys. Currently I have a 4 bulb HO t5 with two actinic and two 12k bulbs. I'm thinking about replacing one of the 12k bulbs with another blue light, possibly the lagoon blue or super actinic. Would that benefit zoa/paly growth and would it bother the fish? I don't plan on adding sps or lps, and wouldn't mind the overly blue tint to my tank. Any input is much appreciated!!
