There's a bulkhead in this aquarium I have, I want to get rid of the bulkhead & hole. I'm siliconing a piece of glass over the hole. I've already siliconed glass to the outside & I was about to silicone another piece of glass over the inside of the bulkhead's hole but realized that would leave an air space in the hole sandwiched between the two new pieces of glass. Should I fill the hole in with Silicone first or allow air in the hole or avoid siliconing glass to both sides of the hole. I was thinking if I left air it may expand differently than the glass & spring a leak. I would like to have new glass on both sides of the hole because it's cracked.

Click to expand...

I would definately fill the hole completely with silicone, you could have prolly got a away with just an internal repair, since the water pressure would be against it any ways.
 
Yep all depends where the hole is and how big the piece is. You could have gotten away with the inside patch only, just make sure that the piece you are putting in is large enough to displace the preassure over a large area of the tank.
 
It's a 20 gallon wet dry filter. It would not have more than 10 gallons of water in it & less than half of that will put pressure on this wall with the hole. It should be fine with two sheets of glass on either side.
 
If the tank was designed to have a hole in it ,the strenght of the tank will be fine. As for glueing a peice of glass over the hole, what you should have done is just glued the glass on the inside. By using the laws of physics and if you use silicon like you said ,it will seal automaticly with the pressure on the glass from the water once the silicon is dry. If it is possible take the glass off the out side and just glue the peice of glass over the hole on the inside, you will have much less problems this way.
