So, I was setting my sump up tonight for my 180, and noticed a small crack in it next to the bulkhead. I was going to go ahead and put the bulkhead on and see if there was any way to seal it, but when I went to tighten the bulkhead, that pane cracked in 4 more places. Does anyone know of anywhere in Knoxville that will replace a glass pane and about what it would cost?
