[MW:2516] Re: Brine Tank Material Selection

Plastic, or lining the existing corroded tank with plastic, is likely to be
cheap and effective. Remember that, if you do go for an all-plastic tank,
you need to consider the possibility of impact damage and UV degradation, if
it is located outside.

Cheers,
Owen.
