Hi - We have a 75 gallon reef with a Devils Hand Brown leather coral near the top. We just changed 1 of our 2 metal halides (150 w) from a 10k to a 14k. The light was about a year old. Our devils hand has turned completely green in a couple days. No it is not algae. Did we burn it or will it be ok? That's why we only changed one bulb to slowly acclimate the corals but I was shocked. It doesn't look dead (yet) but just completely green. Any ideas?? Thanks
