Since I aint been anywhere to look, do any of you guys know where I can buy sheets of 1/2" foam rubber? I got a couple minnow tanks that needs insulating and I figured on gluing this on the outside of the tanks to keep water cooler in the tanks. I got a little 25 gal. already like this but I bought it that way and wanted tpo do my 55 gal. minnow tanks the same way. Lowes or Home Depot?!? Anybody seen what I am talking about?
