Transform Your Hot Tub Experience with Frog® Water Care

Maintaining crystal-clear, healthy hot tub water has never been easier. Frog® hot tub sanitizers combine the power of minerals with low levels of chlorine or bromine to deliver spa-quality water with less hassle and fewer chemicals. Whether you own a Bullfrog Spa, Sundance, or any other brand, Frog® systems are designed to simplify your water care routine while keeping your spa sparkling clean.

At Hot Tub Things, we're proud to offer the complete line of Frog® products—from the popular Frog @ease® Floating System to Frog Serene® Bromine Cartridges—all backed by our commitment to fast shipping, expert support, and genuine products you can trust.


What Is Frog® Hot Tub Sanitizer?

Frog® is a revolutionary water care system that uses mineral technology to reduce the amount of chlorine or bromine needed to sanitize your hot tub. By infusing water with natural minerals like silver and zinc, Frog® helps kill bacteria, control algae, and keep water balanced—all while being gentler on your skin, eyes, and swimwear.

The result? Softer, cleaner water that requires less maintenance and fewer harsh chemicals.


Key Features & Benefits

  • Reduces chlorine use by up to 50%: Enjoy gentler water that's easier on skin and eyes
  • Mineral-based technology: Silver and zinc ions naturally sanitize and condition water
  • Easy to use: Pre-filled cartridges snap into place—no measuring or mixing
  • Long-lasting: Each cartridge lasts 3–4 weeks depending on usage
  • Compatible with most hot tubs: Works with Bullfrog, Sundance, Jacuzzi, and more
  • Eco-friendly: Less chemical waste and fewer refills

How Does Frog® Work?

Frog® systems use a two-part approach:

  1. Mineral Cartridge: Infuses water with natural minerals that condition and sanitize
  2. Sanitizer Cartridge: Delivers a controlled dose of chlorine or bromine

Together, these cartridges work in harmony to keep your water clean, clear, and balanced—without the guesswork or daily testing.

Popular Frog® systems include:

  • Frog @ease® Floating System – Self-regulating, flip-and-forget convenience
  • Frog Serene® Bromine System – Ideal for in-line installation
  • Frog Maintain® Mineral Cartridges – Boosts any existing sanitizer routine

FAQs

Q: How often do I need to replace Frog® cartridges?
A: Mineral cartridges last about 4 months, while sanitizer cartridges last 3–4 weeks depending on hot tub usage and size.

Q: Is Frog® compatible with my hot tub brand?
A: Yes! Frog® systems work with most major brands including Bullfrog Spas, Sundance, Jacuzzi, Hot Spring, and more. Check your owner's manual or contact us for confirmation.

Q: Can I use Frog® with saltwater systems?
A: Frog® is designed for traditional chlorine or bromine systems. For saltwater spas, consult your manufacturer or our support team.

Q: Does Frog® eliminate the need for shock treatments?
A: While Frog® significantly reduces chemical use, occasional shock treatments are still recommended to oxidize contaminants and maintain water clarity.

Q: What's the difference between Frog @ease® and Frog Serene®?
A: Frog @ease® is a floating system that uses SmartChlor® technology and flips over when it's time to replace. Frog Serene® is an in-line bromine system installed in your spa's plumbing.
