Wood tank sealing?

[Scavenger]

Thanks for the complements on the tank. This was my first ever attempt at a DIY tank. I did quite well the only things I didn't make were the return pump and the light fixture. I accually built a return pump that flowed around 1200 gph, but didn't use it because I didn't have faith in its "reliability." The 1/4 inch glass works fine for that size as the total height is 20 inches and there are 2 3 inch braces (top and bottem) so the exposed glass is only 16 inch x 48 inch. It's the height and not width or length that put the most water pressure on the glass.
I found all materials locally in nanaimo Home Depot for shop light fixture, fiberglass resin, silicon, wood ect, the glass I got from Ecowood Bladerunners off northfield road. It's all recycled glass and it cost me $5 for it all. Bought the gravel at Freisen Rentals for $5 too. The total cost (minus fish) was about $200. That's not bad for a 137 gallon eh?

Anyway, now I'm in the planning phase for my reef tank and I'll be building that from scratch too.
