I've got a bunch of glass still, but most of it is pretty small pieces. If we were in the same city, I'd certainly offer more help.
Yes, I just silicone the glass together. It's very easy to do, but it does take a bit of practice. I use Mastercraft Window & Door Clear Silicone from Canadian Tire. It's cheap, and it's good for use with aquariums. It even says so on the back. I let the silicone cure for a couple days before doing a two-day water test.
