Wood tanks may be a nice, but after pricing the epoxy at 35$ a litre,"need 10 for 2 coats" and plywood 1" thick at 70$ a sheet, along with the other supplies needed/"Glass".
Eventually the wood will rot and give out.
Try the bargainfinder.
Eventualy you will find a good deal on a large aquarium.
I found a 150gal for 100$
250gal for 50$
Just a thought.
Good luck, and let us know how it's going.
