FROG Replacement Mineral Reservoir for Pool FROG 5400 & XL PRO Cyclers — Prefilled 6-Month Cartridge, Reduces Chlorine

FROG Replacement Mineral Reservoir is a prefilled mineral cartridge that fits Pool FROG Model 5400 and XL PRO Cyclers to simplify pool sanitization.

Keep your pool water clearer and gentler with an easy-to-install mineral reservoir designed specifically for FROG cyclers. Each cartridge arrives prefilled with FROG’s patented sanitizing minerals to work alongside FROG Bac Pacs (sold separately), delivering steady treatment throughout a typical pool season. The reservoir reduces the amount of chlorine needed, lowers maintenance effort, and helps maintain more comfortable water for swimmers.

How does this reservoir simplify regular pool maintenance?

The prefilled reservoir eliminates measuring and messy refills by snapping into the Pool FROG 5400 or XL PRO Cycler. It provides continuous mineral treatment so you spend less time testing and more time enjoying the pool.

• Prefilled cartridge installs in seconds—no pouring or dosing.
• Delivers consistent mineral release over 6 months or one pool season.
• Works automatically with your cycler for steady, hands-off sanitation.

Will the minerals reduce my chlorine use and affect water feel?

The reservoir’s minerals are formulated to cut chlorine demand, typically lowering the amount of chlorine needed to maintain clarity. That reduction often results in softer-feeling water that’s easier on skin and swimwear.

• Can reduce chlorine usage by up to 50% under normal conditions.
• Helps produce smoother, less-irritating water for swimmers.
• Compatible with existing chlorine dosing from Bac Pacs for balanced sanitation.

What compatibility and lifespan should I expect?

This mineral reservoir is built to fit Pool FROG Model 5400 and XL PRO Cyclers; each unit is prefilled and engineered to last about six months or one full pool season before replacement is advised.

• Specifically sized for Pool FROG 5400 and XL PRO Cyclers.
• Prefilled minerals last approximately six months under normal pool conditions.
• Replace at season end or when manufacturer guidance indicates reduced performance.

How does the reservoir work with other FROG products?

The mineral cartridge is intended to operate together with FROG Bac Pacs (sold separately) to provide a combined mineral-plus-chlorine approach. This two-part system balances ongoing mineral protection with periodic chlorine doses for reliable sanitation.

• Pairs with FROG Bac Pacs to control algae and bacteria effectively.
• Minerals lower chlorine demand while Bac Pacs supply measured chlorine bursts.
• Designed to integrate seamlessly into the cycler’s automatic delivery cycle.

Who is this for: Pool owners who want a low-effort, season-long sanitation solution that reduces chlorine reliance and improves water comfort. Ideal for families, busy homeowners, and anyone using Pool FROG Model 5400 or XL PRO Cyclers who prefers automatic, prefilled maintenance components over manual dosing.
