So, one trip to Home Depot, two trips to ACE Hardware and redid all the plumbing, cleaned and moved the sump. Around 8 pm last night plugged in the pump and the corners of the tank were leaking even worse. Earlier in the day, I sealed the bulkheads and they were dry. Water was coming from under the tank somewhere.
Pics after I plugged in the pump. Outside and inside the stand at the same corner.
This morning pulled the bulkheads and found water between the glass. Bottom of the tank is double glass. So, sealed the inside of the holes, added a bead of silicone to the bulkhead for extra measure and put the back. Pics are the water and gunk between the glass. Third pic shows silicone I was able to force about 1/8 inch between the glass. Hopefully this does the trick.
