Mineral Guard Mechanical Ioniser

AstralPool Mineral Guard requires no power just water flow, combined with the patented CRT (Controlled Release Technology) it eliminates the need for constant testing and measuring of copper and silver levels. In fact we guarantee that our levels will remain below the staining threshold, and you won't risk voiding your pool shell manufacturer's warranty, whilst maintaining a perfect level of secondary sanitation.

Note: That Mineral Guard MUST be used with a primary sanitiser such as chlorine* or with a saltwater chlorinator. Once installed just replace the Mineral Guard cartridge every 6mths to provide perfect health for your pool.
