AstralPool Mineral Guard Mechanical Ioniser (WN000041)

The AstralPool Mineral Guard is a mechanical ioniser that acts as a secondary sanitiser for your pool, allowing you to reduce chlorine use by up to 50%*. It uses natural minerals with a long history of keeping water safe and bacteria-free. Unlike UV, ozone, or AOP systems, Mineral Guard leaves a residual sanitiser in the water — maintaining water health even when the pump is not running.

Mineral Guard requires no power — only water flow and chlorine to activate. It installs easily in-line with your existing filtration system and is guaranteed not to stain your pool. No copper testing is required.

*Australian standards recommend never using less than 1ppm of chlorine.

Key Benefits

• Reduce chlorine use by up to 50%* for a healthier swimming environment
• Leaves a residual sanitiser in the water — effective even when the pump is off
• No power required — only water flow and chlorine needed to activate
• No stain guarantee — unlike copper-based ionisers, Mineral Guard will not stain your pool
• No copper testing required
• Controlled-release technology for consistent sanitisation
• Easy installation — fits in-line with existing filtration
• Compatible with all chlorine delivery systems (salt chlorinator, liquid, tablet, granular)

How It Works

Water flows through the Mineral Guard cartridge, releasing natural minerals into the pool water. These minerals work alongside chlorine to sanitise the water, reducing the chlorine demand. Because the minerals remain dissolved in the water, sanitisation continues even during periods of no pump operation — unlike UV, ozone, or AOP systems which only work when water is flowing through them.

Frequently Asked Questions

Can I use Mineral Guard with my existing salt chlorinator?

Yes — Mineral Guard is compatible with all chlorine delivery systems, including salt chlorinators, liquid chlorine, tablets, and granular chlorine. Simply reduce your chlorinator output or chlorine dosing by up to 50% once Mineral Guard is installed and the minerals have reached their working level in the water. Always maintain a minimum of 1ppm free chlorine as recommended by Australian standards.

Will Mineral Guard stain my pool or equipment?

No — AstralPool Mineral Guard carries a no stain guarantee. Unlike traditional copper-based ionisers, Mineral Guard is specifically formulated not to stain pool surfaces or equipment. No copper testing is required.

How is Mineral Guard different from UV, ozone, or AOP systems?

UV, ozone, and AOP systems only sanitise water while it is actively flowing through the system. When the pump stops, their sanitising effect stops too. Mineral Guard leaves a residual sanitiser dissolved in the pool water, so it continues to protect the water even during periods of no pump operation — such as overnight or during power outages.
