That's definately a good idea. I used 1/4 thich so it bows more than it warps, but I could see problems with thinner sheets. With the frame on the bottom and the light on top it keeps its shape just fine. I probably wouldn't use anything thinner than 1/4 inch though.tad604 said:If your going with plexi glass.... I wouldn't put any frogs in it till you left it up there (with the light comin on and off and hte tank being kept humid) for a couple weeks.
I tried using plexi glass (3/8ths inch) for a lid... and it warped so much that there was a good inch or two gap around the edges.

That's what I plan on doing when I get my 1/4" OP4 from Paul at FCA. I plan on getting something like the 1/4" channel here:MoonRacerDave said:Anybody try a using a strip of aluminum on the edges of the acrylic to keep it from warping?
I actually think you are right. Window screen can block as much as 50% of the light hitting it. It's just a matter of the ratio of surface area of screen material to that of the open space.hexen84 said:Ok I was kinda mistaken about the screen thing and uv light. It is only extremely small gauge screen (really small holes) that blocks the uv rays. hope this helps
