Free Shipping $100+ | Genuine Spa Brand Products

SmartChlor is a self-regulating chlorine system that automatically adjusts sanitizer output based on your spa's needs—no daily testing, no constant adjustments. When paired with the FROG mineral cartridge in your Bullfrog Spa, you'll use up to 75%* less chlorine while enjoying softer, fresher water with virtually no chemical odor.

Each cartridge lasts 3-4 weeks depending on usage, giving you up to 3 months of worry-free spa care with this convenient 3-pack. It's the perfect solution for Bullfrog Spas owners who want premium water quality without the hassle.

How Does FROG @ease SmartChlor Work?

The FROG @ease system uses a unique combination of SmartChlor® and minerals to create what we call "Self-Care" for your spa. The SmartChlor cartridge releases a low, consistent level of chlorine that's automatically regulated based on your spa's sanitization needs.

When paired with the FROG Mineral Cartridge (sold separately), the minerals destroy bacteria while conditioning the water, allowing the SmartChlor to work at a much lower level. This dual-action approach means you use less chlorine, enjoy better water quality, and spend less time on maintenance.

The result? Water that's noticeably softer, cleaner, and more inviting—with that "just-filled" fresh feeling that lasts week after week.
