     If you're going to put living things in the tank,
you must use  
aquarium-grade silicone, which is more expensive.

 die.

        A plastic liner in a plywood box  
would be cheaper and easier, and less prone to
leakage.


It seems to me that the hurdle to jump here is not to
consider the weight of the water and the tanks ability
to restrain this weight. A wooden frame about the
length of three tea chests with flying buttresses are
all thats required.

It is the abilty of an applied material on wooden
slats to waterproof the surface of the tanks OSB,
neighbours recycled old fence or any old reclaimed
flat material insides. Surely we have this material
already in use somewhere else to waterproof a surface?
Foundation waterproofing material or resin polymer
concoction?

The tank will become hot so material melting is an
issue but what about EPDM liquid rubber on a solid
tank inside wall and bottom? Or even use a stickdown
roofing membrane system. Easy to repair. (Just put
another plastic liner in) but a solid sided tank will
provide a measure of control and the ability to put
pipes right where they should go and have a main drain
out of the tank and other gravity channels and
possibly make insulating the tank easier with sheets
of XPS
