Real bad news......my tank is leaking! It's old, and custom build (poorly) and unfortunately an unusual size (60" x 18" x 21"). I've spent the afternoon calling a number of LFS's with no luck....and the most promising spent the time with his multiple suppliers and tells me that that size is no longer available (in glass). The best he could do is the same footprint, but 26" high. So to attempt to slow the leak, I mixed epoxy maybe six times and smeared it all over the corner that's leaking.....both inside and outside. Not pretty, but now only down to just wetness at the location. Not sure what I'm going to do......not happy!
