Reduce your chlorine usage by combining the AstralPool Mineral Guard along with your salt chlorinator or chlorine dosing system. Using Nature 2 technology, Mineral Guard features a controlled release of silver and copper ions from a replaceable cartridge into the pool water to effectively kill bacteria and algae for up to 6 months. As the release of the copper and silver ions is controlled, there is no risk of staining or over-dosing (when used as directed).

Mineral Guard uses no electricity, is compact in size and therefore easy to install alongside existing equipment.

Replacing the Mineral Guard Cartridge is easy and takes less than a minute.

Note: Mineral Guard MUST be used with a primary sanitiser such as chlorine or with a saltwater chlorinator.

DO NOT use with PHMB / Biguanides (eg. Aqua Fresh), bromine-based sanitiser products, copper based algaecides or freshwater sanitisation systems.

DO NOT use soda ash with this product.
