Fixing a leak while water in the tank?

[Tor-Eriik]

No, i do not have a leak first of all I just wonder, when you build a monster like this, the unexpected can happen, what do you do if your not able to tap it all down? Lets say a leak in the bottom of the tank.. Is there any stuff you can use to fix that kind of leak? Under water repairment?

That is what happend to my tank i tried to fix it with Tec7 but it didn´t work. I guess with that height the pressure i to high.

I hope you don´t have to deal with that.

Lykke til

Cant see it working as any substance you try to repair it with wont stick or bond the glass while wet it may do for a short while but will leak eventually

There are epoxies that work and cure underwater, but at that pressure I'm guessing they wouldn't be able to seal a leak, it would probably just be squeezed through it......just a guess though.
