sealing a tank...

[toehead11183]

I have a 55g that i'm trying to add a glass divider in the middle of the tank. I'm trying to add volume to the tank and build a bigger sump. Is there anything special about siliconing glass in a tank? I know to clean all the glass very well and let the silicon to cure for a few days before adding water. Anything elso i dont know about?

I picked up an old 55g for cheap and i mean OLD. The glass is 3/8 thick on the ends. Anyhow, i filled it to see if it would hold and it failed. The corner seam blew out. How do i fix it?

You'll need to scrape off old silicon and clean the surface between the panes

At this point you might have to look at taking the tank, or at least the one full pane off of the tank and resealing it.

I used a razor blade to get the excess silicone off and used windex and a brillo pad to get the rest. I dont think its worth fixin so i siliconed it and im going to gorilla glue the brace and sell it for a reptile tank.
