What thickness and will you be at the swap? If you let me know tonight, I MIGHT be able to take care of this for you. My glass guy normally caters to the construction crews and might be closed on Saturdays. Easy enough to check tomorrow though.
What are you using it for? If it's a non pressure application (in sump as a baffle) then 1/8" should be fine. If you're using it in a pressure application, then 1/8" might not be sufficient. Give me a little more detail and we can figure out exactly what you need.
its a diy slpash shield in my bio cube ...i mounted my light (150w mh) and the uv glass but to much of gap between that glass and my shield ..so i can fit another pc there ..the first pc of glass i got for lowes crack ...under the heat i guess...since than i mounted
to more fans to blow on the light assy ...the salt creep is all over my other bulbs ..and with it seal (hood) my water temps where alot lower ...but now i have the cut out and they stated to get up there so i have a huge fan keeping me cool right now
