FROG SmartChlor Replacement Cartridges 3-Pack with DropH Alkalinity Decreaser & Maintain Shock — for Hot Tub Floating System, Low-

FROG @Ease Replacement SmartChlor Cartridge 3-Pack with pH and Total Alkalinity Decreaser plus one Maintain Shock is a ready-to-use hot tub water treatment kit that delivers low, steady chlorine levels while correcting pH and alkalinity.

Keep your hot tub water clear and comfortable with a compact, prefilled cartridge system from FROG. This replacement pack supplies three SmartChlor cartridges, a DropH Total Alkalinity Decreaser, and a single-dose Maintain Shock to work with the FROG floating Mineral Cartridge. Together they simplify maintenance by combining mineral sanitation with a calibrated, slow-release chlorine formula designed to reduce overall chlorine demand.

How does the SmartChlor system simplify hot tub sanitation?

The SmartChlor cartridges dispense a patented, low-dose chlorine formulation that maintains a constant, measured sanitizing level without frequent adjustments. Because the chlorine is released gradually, you avoid sudden spikes and the need to test and dose several times each week.

• Three prefilled cartridges for continuous treatment over multiple weeks
• Self-regulating release—no manual dosing required during cartridge life
• Designed to pair with FROG mineral cartridges for balanced sanitation

What additional water balance support is included and why it matters?

This kit includes a DropH Total Alkalinity Decreaser to help bring high alkalinity into range and a Maintain Shock to oxidize contaminants and refresh water clarity. Correct alkalinity and periodic shock both stabilize pH and prolong cartridge effectiveness, supporting softer water and fewer maintenance tasks.

• DropH Decreaser corrects elevated alkalinity that can cause cloudy water
• Maintain Shock provides a single shock dose to eliminate organic build-up
• Combined use helps the mineral and chlorine system work more efficiently

How long does each cartridge last and how often should I replace them?

Cartridge life varies by tub volume and usage, but each SmartChlor cartridge typically lasts three to four weeks. Replace cartridges in sequence so there is continuous low-level chlorination; use the included DropH and Maintain treatments as needed based on test readings or manufacturer guidance.

• Average cartridge life: 3–4 weeks depending on hot tub size and use
• Rotate cartridges for uninterrupted sanitation
• Test water periodically to determine if additional adjustments are required

Will using this pack reduce chlorine exposure and protect tub surfaces?

The SmartChlor technology is engineered to keep chlorine at a lower, steadier concentration than many traditional dosing methods, which can lessen irritation for skin and swimwear and be gentler on hot tub components. Pairing minerals with the calibrated chlorine formula typically reduces total chlorine demand.

• Patented formulation keeps continuous, low chlorine levels
• Mineral support reduces overall chlorine usage compared with standard treatments
• Helps maintain clearer, softer-feeling water with fewer harsh chlorine spikes

Who is this for: This replacement kit suits hot tub owners who want a low-maintenance sanitation routine without daily dosing—especially those who favor mineral-enhanced systems and prefer steady, moderate chlorine levels. It’s ideal for owners of FROG @Ease floating systems seeking convenience and balanced water care, and for anyone wanting to simplify tub chemistry while protecting surfaces and skin comfort.
