A plywood tank that can be disassembled without destroying it?

Yes using a pond liner attached to front side with the viewing glass u should be able to disassemble with no problem

I'm currently building a portable 2 piece FRP plywood epoxy resin tank, that will be about 10 ft long x 2 ft wide x 2 ft high. Each side of plywood tank will be about 5 foot long, each being lined with 4 feet of FRP paneling using FRP adhesive to permanently hold them in place, leaving 1 foot at the ends for a FRP patch to connect the tanks during final assembly. The exterior will be braced with 2x4 framing and plywood, which will be screwed into place, and removable when I take apart the tank. That interior center seam will be patched with a small pieces of FRP siliconed into place, so that they can be removed later on. The bottom of the tank will have two layers of 3/4" plywood. The interior FRP panels will be sealed with 2 coats ACR MAX Epoxy resin also. The FRP patch will be sealed with Epoxy Resin separately, once again so that the patch can be removed later.


I'm about half way done building the stand right now, but when the tank is done and holding water in my garage, I'll probably start a new thread with lots of pics. After that I'll be taking the tank apart, and moving it inside my house into the fishroom.

Here's my design: (you can see where the FRP patch will be inside the tank)

i thought about building a plywood tank that bolts together before buying my 300... it is doable, like you say use liner and silicone the edges as in normal tanks. the timber need to be massively over engineered to avoid any flex at all though! good luck my friend keep us posted. a concrete shuttering carpenter could probably build it in a day if you write up a plan and get all the wood.
