Looking to build a custom frag tank for myself using 3/8 glass. Dimensions will be 80x18x10. Going to go with an injection mold on it with the silicone at 3mm thick. Just want some opinions about the glass and silicone thickness. Figure with one about 9in of water in it your looking at only 56 gallons so I double I'll see any bowing with 3/8 glass. 1/2 glass is not an options right now. Thickest I can get at a great price is 3/8.
