FROG Replacement Chlorine Cartridges for Pool FROG 5400/6100 Cyclers — 3-Pack 2.2 lb Prefilled Trichlor, Metered Release

Keep your pool water clear and consistently sanitized without measuring loose chemicals. These FROG Bac Pacs arrive prefilled with 2.2 lbs of trichlor each and are engineered to drop into compatible Pool FROG cyclers so the system dispenses chlorine in a controlled, steady way. Sold as a convenient 3-pack, they’re intended to be swapped on a weekly-to-monthly cadence depending on use, weather and pool size.

How do these cartridges fit and work with my Pool FROG cycler?

Each cartridge is shaped to seat securely in Pool FROG Model 5400 and 6100 cyclers. Once installed, the cycler releases a metered amount of trichlor into circulation so you don’t have to measure or guess. That steady dosing helps maintain consistent sanitizer levels between cartridge changes.

• Prefilled 2.2 lb trichlor cartridges for simple drop-in replacement
• Designed specifically for FROG Model 5400 and 6100 cyclers
• Metered release reduces the need for manual dosing
• Replace every 1–3 weeks depending on pool conditions

Will these reduce the amount of chlorine I use?

The FROG delivery system is engineered to release only the chlorine needed to maintain sanitation, which can lower total chlorine consumption compared with some traditional dosing methods. Actual reduction varies by pool size, bather load, sun exposure and other factors. Results are dependent on system setup and pool conditions.

• Metered feed reduces over-dosing compared with manual pouring
• Intended to work with FROG Mineral Technology to balance sanitizer needs
• Helps maintain consistent levels to avoid wide swings in chlorine
• Change frequency depends on usage and environmental factors

How often should I replace each Bac Pac cartridge?

Replacement intervals range from about one to three weeks based on pool size, weather, bather load and the cycler setting. Check your pool’s free chlorine levels regularly and swap cartridges when sanitizer begins to drop. Keeping spare cartridges on hand prevents gaps in sanitizer delivery.

• Typical replacement window: 1–3 weeks per cartridge
• Monitor free chlorine to confirm optimal timing
• Sold as a 3-pack for ongoing maintenance and convenience
• Longer life in shaded or lightly used pools; shorter in hot, busy conditions

Is it safe and easy to handle these prefilled cartridges?

Prefilled Bac Pacs eliminate the need to handle loose granular chlorine, simplifying maintenance and reducing mess. Follow the cycler’s installation instructions and safe chemical handling practices—wear gloves and keep cartridges dry until use. Store unopened cartridges in a cool, dry place away from children and pets.

• Prefilled design minimizes direct contact with pool chemicals
• Follow manufacturer safety guidelines for storage and installation
• Keep away from moisture and incompatible substances
• Dispose of used cartridges per local regulations
