Having acquired 3 pieces of it now, I’ve found it to just take time to develop its ideal color. I kept it under t5, metal halide, and as of a week now, led. I have witnessed it be More green dominant under lower par. Higher par and warmer kelvin will pull the more gold/purple colors. That has been my experience with it to date over the past few years.
this is mine grown primarily under 20,000k metal halides at about 400-500 par, BUT presently images under reef breeders photon v2 units, 60% blue/violet, 30% white, 5% red and green at about 250 par. Granted it’s been only a week. But this is what it looks like for me now given those conditions. Instant ocean salt. Regular water changes, 6-8 dkh , heavy heavy heavy flow. 0.03-0.1 ppm po4. Hope thst helps
