Plywood tank, long term option?

[cedwards04]

I've searched around and found plenty of people who have built plywood tanks, but I have not been able to find anyone commenting on how well it worked out long term. I'm talking 5+yrs of use. I'm looking for an economical way to build a very large frag system and thinking plywood may be a good option, but I want to make sure the thing isn't going to fall apart from rot in a year or 2. I am no stranger to wood working and have all the tools and skills needed to build something quite sturdy, im more concerned with the coatings used for the inside holding up long term.

Can anyone comment on their life expectancy that has had one, or point me to a thread where this has already been discussed? Thanks.

I would suggest instead getting acrylic and weld-on and making an acrylic tank.

This is basically my back up plan. I've built some small things from acrylic (ato reservoir, overflow boxes, etc), so im familiar with it. Plywood would appear to be significantly cheaper, but it just may not be a good option in the end.

Plywood sounds good but you'll be best to buy a cheap frag tank .nothing good comes from "plywood and cheap".
