I upgraded from a 29 gallon biocube to a JBJ 45 gallon around Thanksgiving this year and quite a few of my corals are bleaching slowly. I went from 1 light on my 29 to 2 lights on the 45 and I'm wondering if maybe I overestimated the amount of light needed. All the corals are under more water than they were in the biocube but that probably doesn't reduce the par too much? I do not have a par meter. Corals that are bleaching are a tubbs stellata monti, Miami hurricane chalice, space invader chalice another chalice and some cyphastrea. Nothing is white but it's definitely losing color. Today I raised the lights about 6 inches to see if that helps at all. Does it look like I have these set too high? Come on at noon and off at 8. Thanks!
