I'll chime in...

The first thing you'll hear around here (because its true) is that 180gal is way below the cost-effectiveness threshold to make a build worthwhile. Unless you're in it for the satisfaction of DIY. You're going to spend over the cost of buying one and it'll cost you a lot of time and effort too and the result will be a summary of your build skills.. (in other words, it might leak)

But to answer your question, 3/4 ply is fine though it depends on the depth you're planning... but its doable no matter the depth if you use the right level of reinforcement. Check through the DIY section to get an idea of the various builds that was done and successful.

There are successful ones that are just a plywood box... but I think the failure rate is higher to try this route... better are the rigid wood frames with a plywood lining. Doubling up is definitely better than not doubling up. Especially if you're planning on using a brittle epoxy to seal which the slightest flexing will make crack.
