The laptop or other device you're using should have a white screen on it for this to work properly. Just open a blank page with Notepad or some other simple word processing program. As you rotate the LCD screen, if the glass is tempered you should either see a changing pattern or the screen on the other side get dimmer/brighter as you rotate it through at least 90 degrees. Hope this makes sense, if not a search will likely bring up something with a graphic example of what I'm talking about. Seen a few on other forums.

Someone works with a polarimeter for a living , I'm +1 with Doug on this one Magicians and similar morphs have horrible track records in captivity. Makes me wonder if it's something in excess melting them or something they are lacking, funny thing's these zoas be that's for sure.

The Magicians are up for debate, those are tough to keep ime. The African Blues and the Darth Mauls were doing very good and were in my tank for 1 year and almost 2 years respectively. They grew very, very slowly though. The Grape Caulerpa took over, and smothered the Zoas which I think is the main reason for their demise. I need to get that darn sump put together, but jeez I have a lot on my plate right now!

That's a pretty fancy trick with the sunglasses! Hubby's sunglasses are polarized, but mine are not, and he won't be home for another 10 days or so. I don't think the tank is tempered...
