ive gotten a good deal on metal halide set up and i plan to put it on my 220g fowlr. it will be three 175w bulbs and im not sure which bulbs to get, 10k, 14k, or 20k. i know all companies are different, but these will be south pacific sunlight. my tank isnt going to have any corals so photosynthetic quality is not much of a consideration. just looks, i like the bluer looks of the 20k's but dont want to drown out the colors of my fish with too much blue. i also have 100w of standard lighting that i can put actinic bulbs in if i need to. any suggestions?
