Broke the glass in my aquamedic MH

Maybe you can devise a method of branding corals to know who they belong to. 
Can't believe I missed this....
Sorry to hear about the light. If it's gonna be awhile to get the replacement glass, I have a dual PFO HQI 250 Watt DE MH with pendants and one month old 14K Pheonix bulbs laying around doing nothing.
You're welcome to borrow it, although it doesn't have a hanging kit as it was mounted in a canopy. I am sure you or hubby could jury rig something, though. LMK

I'm suprised Eliot isn't using this as an excuse to rig up a blast furnace to temper the glass himself. 
Cindy,
I recently also broke the glass shield on a Reef Optix DE fixture. I tried to get tempered glass from a local shop (called quite a few) and they gave me ridiculous $ figures for the glass. One shop told me that some type of laminate would be fine. Like an idiot I believed them. Shattered within a day or so, but at least it didn't fall into the tank like the first one.
Anyhow, in the end I called the place I purchased it from and they had the manufacturer send me out a piece of replacement glass. It was not expensive from the manufacturer, and they got it to me pretty fast (5 days or so).

Twice-Tempered glass!
Just FYI- glass will filter out most UV radiation, which is designated into 3 categories (UVA, UVB, UVC). UVC is the most energetic and hence dangerous and it's uses include steralization devices, such as steralized hoods in bio-labs. Fortunately, most of this spectrum is filtered out by the ozone layer. This is produced by the MHs and is why we need the glass covering the lamp. Glass also filters out UVB, the type of radiation that is responsible for tanning (or sunburns in my case), and producing Vitamin D. Lastly, UVA is the least energetic of the UV light and least dangerous (although does damage the skin to some extent). UVA is not filtered by glass.
As a side note, I've always wondered if we are depriving our corals of energy they would normally get in the wild by cutting out UVB.
Hope that didn't hijack the thread too much! I'm sure you'll get the problem sorted out soon, Cindy and your corals will all be just fine.
