Yes, LFS need help too. Give me some input. The glass that cover the halide over my tank shattered into small pieces and drop into the aquarium. So far all the acros and monti turning white(snow flakes) not bleach. clams been shut but still attach. mushrooms are shrinking. Xenias death and the rest of the coral all looking bad. What chemical could have been release in the water by the glass that so dangerous. This hapen on Saturday morning and looking worst as hours gone by. I did a 50% water change yesterday but does not look like it help. This is a 215 gal tank been running 14 months and very healthy as far water chemistry. Thank you.

Were the lights run for any length of time after the glass shattered? That outer glass piece is the UV shield, and if the lights were still on after it shattered, your corals could have got a pretty high dosage of UV radiation, depending on how long they were exposed.

I think that was the case. I run the light about three hours a day since.

That is the case if they are Double Ended MH bulbs. Regular screw end bulbs, the glass bulb itself is the UV shield.

It's a bulb inside a bulb, with the outer bulb being the UV shield. It's possible to break the outer UV shield and the inner bulb will still fire.

But if I remember right, Kenny told me he was running 150w DE's over that tank. In either case, I would stop running the lights completely until the problem was corrected.

Yeah, what Mikester said.

It is double end. Mike is right the radiation burn the corals.
