im curiour on how long a plywood tank will last until it has to be rebuilt or it starts to rot? any body care to help. i wanna make a 12ft x 8ft x 6ft tank.
Depends on how well you build it. It will last as long as the materials you use. Use good wood, and an appropriate sealant, as well as careful craftsmanship and a ply tank should last 20+ years
