OK, I got the new glass in and installed after painting the viewing window frame with fiberglass resin to get a seal between the liquid rubber and the viewing window. Because I ended up replacing the frame after I broke the firstpiece of glass Ihadto spend some time adding more liquid rubber to the new frame. After everything was resealed and allowed to dry, I filled the tank last night and it has been leak free for over 24 hrs. If it makes it till tomorrow morning, I will drain it, add the sand and driftwood back to the tank, refill and fire up the sump.
