If you are planning to build your own tank they have a section what what is needed and what materials are needed.
I hope this helps

The modern plastic tank will have the longest life. If your building it in remember to box it oversized as the plastic tank will stretch about 1% or 2% on its first filling.

Let the tank sit full and foam the space left in the box , and your set "forever".
