Tempered Glass

[Reef_Ready]

Thanks for the replies gentlemen. I'll try the Polarized lens thing and see what happens.

I was unclear on my original post, I don't know what make of tank this is, but I went to the AGA site (just as reference) I found that their tanks are not tempered glass but annealed

"Heavy duty annealed glass construction is used so any panel can be drilled for use with nearly any filter set-up..." This is for their 75 to 180gal tanks.
