Nature2 G45 is a direct-replacement mineral cartridge that helps keep inground pools up to 45,000 gallons clearer and reduces the need for heavy chlorine while fitting Nature2 Professional G and Pro G Plus vessels.

Designed for homeowners and service pros, the Nature2 G45 mineral cartridge combines mineral-based sanitizing technology with an easy drop-in replacement format. It works continuously to help control algae growth and bacteria, making pool maintenance simpler without relying entirely on elevated chlorine levels. This cartridge is sized and engineered specifically for use in Nature2 Professional G and Pro G Plus sanitization vessels for inground pools up to 45,000 gallons.

How does this cartridge improve water clarity and algae control?

The G45 cartridge releases sanitizing minerals that inhibit algae and reduce bacterial activity, supporting clearer water between typical chlorine treatments. It works continuously, so you get ongoing protection rather than intermittent boosts from shock treatments.

• Mineral media actively reduces algae growth potential
• Operates 24/7 while installed in the Nature2 vessel
• Helps maintain visibly clearer water with fewer algae blooms

Will this reduce how much chlorine I need to add?

The cartridge is formulated to lower reliance on high chlorine concentrations by supplementing sanitization with minerals. It does not eliminate the need for chlorine entirely but can reduce routine chlorine demand for a more comfortable swim environment.

• Mineral action complements, not replaces, chlorine sanitation
• Often results in lower free-chlorine targets while maintaining safety
• Can lessen chlorine odor and skin/eye irritation associated with heavy dosing

How long does one Nature2 G45 cartridge last and how easy is replacement?

Each cartridge is engineered to provide mineral sanitization for up to six months under normal pool use. Replacement is straightforward: remove the spent cartridge from the Nature2 Professional G or Pro G Plus vessel and insert the new G45 cartridge for immediate continued protection.

• Up to six months of continuous mineral effectiveness
• Tool-free swap into compatible Nature2 vessels
• Simple maintenance schedule helps avoid lapses in protection
