I'm looking into upgrading my tank to a 120 gallon (4'x2'x2'). I want to be able to keep anything I want (softies, LPS, SPS). My question is: Do you have to supplement MH lighting w/ Actinics if you use 10K bulbs? 14K bulbs? Thanks.
10k u would want actinics because it is white, but the 14k is a blueish(mostly favored), and the 20k is a real blue. but it all depends on what colors u want; white, whitish blue or blue.
