TANK CRASH: MH Exploded?!

[Gripenfelter]

This happened to another board member on a local forum. A dragon wrasse jumped out of his tank and smashed his MH bulb. The chemicals in the bulb are volatile and extremely poisonous.

Metal Halide bulbs use rare earth salts along with argon and mercury vapour. The metals and vapours are poison.

Your best bet to ensure the survival of your fish and coral would be to do HUGE water changes.

I always have a quarantine tank running as a back up filled with water from the DT. If possible, transfer everything to a friend's tank ro a quarantine tank until you clean out the tank completely. The metal and poison will not decay and will stay in the water for a very long time.
