Soo sorry to hear about the tank. Bu I have to think it's the Stand, not the tank that caused teh crack twice. If you re-siliconed a new front pane on, then any internal stresses tnat may have been in the tank form a mis manufacture should have been eliminated with the new pane placememnt. Thus, leaving the stand to be suspect. Totally go through that stand to make sure it is not twisting under load. That can cause front pane to crack. Would hate to get a 3rd tank up there and happen again
