Yes! Best of luck man. I just had a silicone issue and drained the tank, then tossed it but then again it was a 29. My dumb ass set it up as it had sentimental value and was--ahem, like 20 years old. So apparently older silicone is good for about 7 years, newer silicone 10. Thank god it was so small. When I set up a new 30 long I realized my floor is not level (old house) and had to shim all over the place. Maybe check ur leveling real good too when u set back up? Could that be what caused this weird split in corner? I hope all goes well. I was stressed over a stupid 29. (They don't call me Wiggie for nothing.)I can't imagine how u feel. Good thing u caught it. Let us know how all goes.
