Frog at Ease SmartChlor Cartridge
Product Overview
A proven choice for hot tubs up to 600 gallons needing steady sanitization without constant dichlor dosing.
Formulated with 1,3-dichloro-5, 5-dimethylhydantoin 81.1%, 1,3-dichloro-5-ethyl-5-methylhydantoin 16.1%, the FROG @ease SmartChlor Cartridge delivers self-regulating sanitization for hot tubs up to 600 gallons. Unlike standard dichlor granules that require manual additions after every soak, this cartridge slowly meters reserve chlorine to maintain water clarity over 3 to 4 weeks. Note: If your spa was previously sanitized with bromine, drain and refill with fresh water before installing.

When To Use This

Common Questions & Instructions
Can I use the SmartChlor cartridge if my hot tub previously used bromine?
No. If your spa was sanitized with bromine, you must drain and refill the hot tub completely before installing the SmartChlor cartridge, as hydantoin chlorine and bromine systems should not be mixed.
How does SmartChlor compare to traditional spa dichlor granules?
Traditional dichlor requires manual additions after every soak, whereas the SmartChlor cartridge automatically meters sanitizer into spas up to 600 gallons to maintain steady residual protection.
How often should I replace the FROG @ease SmartChlor cartridge?
Each cartridge lasts roughly 3 to 4 weeks under standard use, provided your circulation pump and filter operate at least 3 hours per day.
