I saw those videos.. I hope I don't have to empty the whole tank. It looks this is how most people have fixed theirs, with the exception of a video where the repair is done with 2 part epoxy. Emptying the tank will be a pain with the sally light foot, tiger shrimp or watchman. It would be stressful for many. Additionally, when it rains, it pours! Just found a leak from the gasket of the overflow bulkhead. I removed it and it is rigid. I'm soaking it in vinegar to remove all the vermetid snails and old coralline on it. Think a little silicone lubricant will help revive it to where I can use it until replacements arrives? BRS must be thinking "Ooh... yeah... I remember this guy. Welcome back buddy!"
