cracked tank help please

[oregonian]

hey, i just bought a 135? gallon tank. its at least 10 years old via prev owner. when i filled it to check for leaks i found this crack (sorry about crappy pic quality.) its only about 1" but goes below the framing. i also included some poss plans i was going to repair with. the glass pieces i figured do at least twice the length of the crack as well as place another on the inside edge of the tank. my questions are 1. how should i place the glass on the inside on the cracked pane or on the supporting to place pressure farther from the crack and 2. should i just go ahead and reseal the entire tank and if so any good advice for resealing a big tank (i.e. bead size, application pattern)

sorry such a long post but any advice will be greatly appreciated.

here are the pics

Ok, it's a corner chip and outside so that's good. Get the windshield repair kit that's sold auto parts stores for crack/chip repair and use it outside. Put your bracing repair on the inside to dissipate pressure.

I agree with Dr. Joe. Looks like you'll be fishkeeping in the future.

the windshield repair kit is a great idea, I would have never thought of that, but have a similar situation with one of my tanks, so thanks for the idea dr. joe!

thanks dr. joe. does this work if the glass is still in the chip?

 

[Dr Joe]

Absolutely, that's even better.

Don't you have to have a chip smaller than a quarter for those repair kits?

 

[Dr Joe]

No , they work for cracks too.
