I have a metal halide canopy with 3 bulbs total spread out 76" long. I would like to get my tank to display the psychedelic blue color instead of pure white. I bought some string led to mount under the canopy but they are only noticeable at night. My anemone and the one coral I have look so much better under blue light. Do I have any good options for achieving this Without buying a whole new lighting system and ditching halide?
