You will need to acclimate your current corals with the new light. I did the reduced photo period methid listed in the articles section for mine. My ricordia love it. My shrooms
, not so much. I have them somewhat shaded now and they are doing better.
, I did basically the same thing. I went from a 4x55 PC
to a 2x250 MH
setup. Keep in mind the heat issues. I have 2 fans in my canopy and temps are almost hitting 84 during the day. I have kept it down by adding a fan on the sump but that really increase my evaporation.
