They make an aquarium safe silicon that you should be able to get at your LFS or online. Couple of people on here also know of some at Home Depot that is safe but I can't remember the exact name. Must be old age creeping up.

I use GE type 1 without mildew resistance.
Generally if it's safe for food contact surfaces it's safe for aquariums.

The plywood is going inside and it will need to be sealed to the glass

ok i think i got it.........you could cover the ply with epoxy ( none toxic type)........for water proofing

i would then rough up the epoxy coating about 2 inches all the way around to give the silicone a bite... make sure the glass is super clean and test it outdoors when you are none........

might be the same price to get a sheet of glass to drop in the bottom and then seal.....

I use the ge type 1 window and door,never had a problem,it sort of sticks to wood and metal but not very well,I wouldnt trust it to form a long term seal on anything but glass.If the pieces are arranged so the silicone is just a gasket then it could work if well done.

well a piece of glass would cost alot of money and i already have a piece of plywood to use, the galss would have to be 7 feet by 3.3 feet so don't think i can afford to go that route, could i use a pond liner on the bottom and glue it to the galss around the edges of the bottom???
