I know it's a longshot, but I thought someone might have one of these in a fixture they're not using at the moment. I broke Loren's today while cleaning it and need to borrow one while I find a replacement lens cover to buy.

Fixture is this one (http://www.marineandreef.com/PhotoGallery.asp?ProductCode=RES53409).

Its probably 1/8" acrylic. You can probably just get another one cut if you can find a 6ft piece. Maybe two 3 footers? Aside from that, have a LFS call their Royal sales person and ask them to order you a replacement from ESU.

This might be something Sam (Aqua Buys) can do. Thanks! I'll ask him.
