Just getting back into the hobby with a small tank 32 Biocube HQI 150w that I dusted off. Any ideas on supplemental lights? I was going to run the MH for 4 hours to start, then dial it back when the tank was grown out to the way I want it. My old ice caps will not fit. I just need a light that will dim and look good, not actually grow the corals. Any ideas?
