Keeping your hot tub water clean, clear, and comfortable shouldn’t be a hassle. That’s where FROG hot tub cartridges come in—offering a smarter, simpler way to maintain water quality with less effort and fewer chemicals. In this guide, we’ll break down how FROG mineral and chlorine cartridges work, the benefits of each, and how to choose the right options for your hot tub.
How FROG Hot Tub Cartridges Work
FROG systems use a dual-cartridge approach to hot tub care:
-
Mineral Cartridge: Infuses the water with minerals that help kill bacteria and soften the water, reducing the need for high chlorine levels.
-
Chlorine Cartridge: Utilizes SmartChlor® technology, a unique, self-regulating form of chlorine that maintains consistent sanitizer levels and only releases more chlorine when contaminants are present.
This combination delivers what FROG calls “Fresh Mineral Water,” resulting in water that feels softer, smells better, and is easier on your skin and eyes.
The FROG Mineral Cartridge
-
Purpose: Reduces bacteria and helps keep water balanced.
-
Lifespan: Lasts up to four months or until you drain and refill your hot tub.
-
Benefits: Allows for lower chlorine use, making the water gentler and reducing chemical odors.
The FROG Chlorine Cartridge (SmartChlor)
-
Purpose: Provides a steady, self-regulating supply of chlorine sanitizer.
-
Lifespan: Typically lasts 3–4 weeks, depending on hot tub size and usage.
-
How It Works: SmartChlor technology keeps a chlorine reserve that is only released when needed, unlike traditional chlorine, which is quickly depleted by contaminants.
-
Benefits:
-
Reduces chlorine use by up to 75% compared to standard methods.
-
Maintains consistently low chlorine levels for a more comfortable soak.
-
Easy-to-read test strips and a visual indicator (the cartridge flips over when empty) make maintenance simple.
Choosing the Right FROG Cartridges for Your Hot Tub
When selecting FROG cartridges, consider the following:
-
Hot Tub Size: Larger tubs may require more frequent cartridge changes.
-
Usage Frequency: Heavier use can deplete cartridges faster.
-
Replacement Packs: FROG chlorine cartridges are available in convenient 3-packs, making it easy to keep your system running smoothly.
Pro Tip: Pair one mineral cartridge (blue) with one frog chlorine cartridge (silver) for optimal results. Replace the mineral cartridge every four months and the chlorine cartridge every 3–4 weeks for continuous, clean, clear water.
Why Choose FROG for Your Hot Tub?
-
No Mess, No Guess: Prefilled cartridges mean no measuring or handling loose chemicals.
-
Consistent Water Quality: SmartChlor technology ensures your water is always sanitized, without the peaks and valleys of traditional chlorine dosing.
-
Gentler Soak: Lower chlorine levels and added minerals create a more enjoyable hot tub experience.
Frequently Asked Questions
How do I know when to replace my FROG chlorine cartridge?
Use the FROG test strip—if the color is lighter than the SmartChlor Out Indicator, it’s time to replace. The cartridge will also flip over when empty for a clear visual cue.
Can I use FROG cartridges in any hot tub?
Most modern hot tubs are compatible with FROG systems. Check your manufacturer’s recommendations or consult with Pools Plus More for guidance.
Do I still need to shock my hot tub?
Yes, periodic non-chlorine shock (like FROG Maintain) is recommended to keep water fresh and clear.
