How will stony corals react to UV light? Will be running 2x 250W HQI bulbs and at the moment I dont have a UV shield on the light fixture.

It has the potential to kill all of them. Have a look at TonyB's thread on ultimatereef.

Don't do it!

Many years ago in my early reef keeping days, I ran a halide without the protective glass (I didn't know it was a UV shield - I thought it was just there to protect the bulb from splashes). Not only did it burn all of the corals and coralline algae to the point where some corals did not recover, it entailed a trip to A&E for me with eye damage after one evening of rescaping the live rock. I had given my retinas a mild dose of sunburn and my face a much worse dose! I had thought the new halide was just too strong and that was why the corals were getting burnt, so I was moving everything lower in the tank. Little did I know it was the UV - well until the morning at least! :oops:

Get the glass in place ASAP. It's definitely there for a reason.
