RO Preserve
RO Preserve is used to prevent biologic fouling as well as solids from forming a bond with the RO Membrane during long periods of storage. Mix 1 package of RO Preserve with two gallon of pure water to protect your machines. If you are planning on storing in cold climates where freeze protection is necessary, you can substitute the pure water with propylene glycol (RV antifreeze).
*Preserve solution should be changed once every 3 months.
