i would call blacks glass and have them cut you some custom sized glass sheets. Thats what I have for my 120gal. Much cheaper than you can find anywhere else, and you can get it exact to what you need it. As for the lid I have not been able to find a hindge, but the way I set up my closed loop it worked good without the hindge. I siliconed a wood handle on the shorter peice of glass to make the lid. Been working very well so far. And cheaper than anythign commerical.
