Default Building a plywood frag tank. Need some info!

Hey guys,

I'm in the middle of planning a build For a frag tank that has multi tiers out of plywood. It's cheap, easy to design with wood and should be nice and strong. My one issue is sealing the tanks. I've been doing some looking around online and two part epoxy seems to be the way to go. My one problem seems to be I can't find any that are fish safe in Alberta. I called a company in the states but it was 250 dollars for shipping for a 1 gallon paint can because the have to ship as a hazardous material. Does anybody know where I can get some in the Alberta area. Or can recomend a substitute to epoxy?

I never used epoxy. Just glued it and there are enough screws to hold it tight. Painted it and siliconed it.

I used West systems on mine. I was informed once dry it was inert. Let us know how the coraline buildup on the plywood is. Thats really the only thing im worried about. Heres a couple pics of the one I did. I still havent got the glass cut for it yet.

I have a hard time seeing how plywood will be cheaper than glass for a frag tank. 1/4" glass is awfully cheap and a gallon of that epoxy paint is pretty expensive. Glass is also a lot easier and you'll have less exposure to the fumes which will shorten your life

Typically you can get 1/4" glass cut to size for no more than $5 per square foot. I suggest pricing this out before going though the trouble involved with a plywood build.
