Lighting Question

[StephenA]

I cleaned the glass on my 150Watt MH lights on Friday. The glass was pretty dirty. Ever since then my corals look pretty bad. Could I be burning them with to much light? My leathers are closed up and slimmey, my acro's aren't happy, birdsnest is looking lighter and my anemones have moved closer to the sand. The only thing that is happy are my clams and christmas tree rock.

i would think that if they were really really dirty that you increased the intensity a bit by cleaning them. cut your photoperiod down a couple hours for a week or so and let them readjust.
