Easy, Self-Regulating Water Care for Compatible Bullfrog Spas

Make maintaining clean, clear spa water easier with the FROG® @ease® Simplicity® System Kit for Bullfrog Spas. This complete startup kit combines a FROG @ease Mineral Cartridge with regular-size SmartChlor® technology to sanitize your hot tub two ways while reducing the need for frequent measuring and chemical adjustments.

The regular-size SmartChlor cartridge is recommended for Bullfrog 5-, 6-, and 7-size hot tubs equipped with the flat, rectangular Simplicity Filtration System. SmartChlor automatically releases sanitizer as the water needs it and maintains a low free-chlorine level with a reserve ready to respond when additional sanitation is required.

The startup kit includes one Mineral Cartridge, one regular-size SmartChlor Cartridge, one FROG Jump Start® packet, and one bottle of FROG @ease Test Strips.

🧩 Compatibility & Fitment

This system kit is designed for Bullfrog Spas equipped with the flat, rectangular Simplicity Filtration System. Compatible applications include:

  • Bullfrog M Series models with Simplicity filtration
  • 2023 and newer Bullfrog A Series models with Simplicity filtration
  • Bullfrog 5-, 6-, and 7-size spas as the recommended regular-size application
  • Spas equipped with the updated Bullfrog Simplicity Filter Housing, part number 10-04669

Important: This cartridge system requires the updated Simplicity Filter Housing, part number 10-04669. Bullfrog Spas manufactured before 2024 may have the previous housing design and may require this retrofittable replacement before the cartridges can be installed.

The updated housing can be retrofitted into compatible Bullfrog Spas already equipped with the Simplicity Filtration System. It does not convert a spa with cylindrical filters or another filtration design into a Simplicity system.

This regular-size system is not the same as the triangular FROG @ease Classic system used in Bullfrog X Series, STIL, and many older Bullfrog models. Confirm your filtration system, cartridge shape, spa model, and water capacity before ordering.

🔹 Key Benefits

  • Complete startup system for compatible Bullfrog Spas
  • Recommended for Bullfrog 5-, 6-, and 7-size hot tubs
  • Self-regulates to release sanitizer as the water needs it
  • Uses up to 75% less chlorine than traditional chlorine programs
  • Maintains approximately 0.5–1.0 ppm free chlorine when water is properly balanced
  • Creates a SmartChlor reserve that activates when additional sanitation is needed
  • Helps reduce chlorine odors, frequent testing, and daily chemical adjustments
  • Minerals and SmartChlor work together to sanitize the water two ways
  • Provides cleaner, clearer, and softer-feeling Fresh Mineral Water®
  • Includes the startup shock and specialized test strips needed to begin

📋 How to Use

  1. Confirm that your spa uses the flat, rectangular Simplicity Filtration System and the updated Simplicity Filter Housing 10-04669.
  2. Fill the hot tub and confirm that the circulation and filtration equipment are operating properly.
  3. Use a FROG @ease Test Strip to test the water.
  4. Balance total alkalinity to 80–120 ppm.
  5. Balance pH to 7.2–7.6.
  6. Balance total hardness to 150–250 ppm.
  7. Add the included FROG Jump Start packet according to its label directions to establish the initial chlorine residual.
  8. Set the regular-size SmartChlor Cartridge dial according to the setting chart for your Bullfrog Spa model.
  9. Set the blue Mineral Cartridge to its designated operating setting as directed in the instructions.
  10. Insert both cartridges into the appropriate openings in the Simplicity filter housing until they latch securely.
  11. Test the water regularly with FROG @ease Test Strips and replace the SmartChlor Cartridge when the Out Indicator shows that it is depleted.

The regular-size SmartChlor Cartridge typically lasts approximately three to four weeks in an average 400-gallon hot tub. Actual cartridge life varies based on spa size, water temperature, bather load, filtration, water balance, and dial setting.

💬 Southern Leisure Says

This is the correct starter kit for many 5-, 6-, and 7-size Bullfrog A Series and M Series spas using the updated Simplicity cartridge housing. It includes everything needed to start the FROG @ease program: minerals, regular-size SmartChlor, startup shock, and the correct test strips.

Before ordering, inspect your filter compartment carefully. Bullfrog Spas manufactured before 2024 may require the updated Bullfrog Simplicity Filter Housing 10-04669. If you have a larger 8- or 9-size Bullfrog Spa, the XL Simplicity System Kit will generally be the better choice.

We strongly recommend using only FROG @ease Test Strips with this system. Standard strips can misinterpret the SmartChlor reserve and make the total chlorine reading appear higher than the active free-chlorine level.

🧼 Care & Maintenance

  • Test the water regularly with FROG @ease Test Strips.
  • Maintain pH between 7.2 and 7.6.
  • Maintain total alkalinity between 80 and 120 ppm.
  • Maintain total hardness between 150 and 250 ppm.
  • Replace the regular-size SmartChlor Cartridge when the test-strip Out Indicator shows that it is depleted.
  • Replace the Mineral Cartridge every four months or whenever the spa is drained and refilled.
  • Use FROG Maintain® or another compatible non-chlorine MPS shock as directed for recurring maintenance.
  • Do not substitute routine dichlor shock because cyanuric acid buildup can interfere with SmartChlor performance.
  • Clean or replace the spa filters according to Bullfrog’s recommendations.
  • Keep unused cartridges sealed and store them in a cool, dry, well-ventilated location.
  • Always follow the printed instructions supplied with the system and chemicals.

❓ Frequently Asked Questions

Which Bullfrog Spas should use the regular-size System Kit?

The regular-size SmartChlor system is recommended primarily for Bullfrog 5-, 6-, and 7-size hot tubs equipped with the flat Simplicity Filtration System. Larger 8- and 9-size models generally use the XL system.

Will this system fit every Bullfrog Spa?

No. It is designed for compatible Bullfrog M Series and 2023-or-newer A Series spas using Simplicity flat-filter filtration. It does not fit the triangular Classic cartridge holder or replace systems used with cylindrical filters.

Which filter housing is required?

This system requires the updated Bullfrog Simplicity Filter Housing, part number 10-04669. Spas manufactured before 2024 may require this retrofittable housing upgrade.

Is filter housing 10-04669 included?

No. This kit includes the water-care cartridges, Jump Start packet, and test strips. The Bullfrog Simplicity Filter Housing 10-04669 is sold separately.

What is included in the System Kit?

The package includes one regular-size SmartChlor Cartridge, one Mineral Cartridge, one FROG Jump Start packet, and one bottle of FROG @ease Test Strips.

How long does the regular-size SmartChlor Cartridge last?

It typically lasts approximately three to four weeks in an average 400-gallon hot tub. Actual life depends on water capacity, temperature, bather load, filtration, water balance, and the cartridge setting.

How often should I replace the Mineral Cartridge?

Replace it every four months or whenever the hot tub is drained and refilled, whichever occurs first. The minerals are depleted after four months even if material can still be heard inside the cartridge.

Why do I need FROG @ease Test Strips?

SmartChlor creates a sanitizer reserve that standard test strips may interpret as elevated total chlorine. FROG @ease Test Strips are designed for this system and include an Out Indicator showing when the SmartChlor Cartridge needs replacement.

Do I need to shock the spa?

Yes. Use the included FROG Jump Start packet during startup. For recurring maintenance, follow FROG’s directions and use FROG Maintain or another compatible non-chlorine MPS shock. Routine dichlor shock is not recommended because cyanuric acid buildup can reduce SmartChlor’s effectiveness.

Can I switch from bromine to this system without draining?

No. If the spa was previously maintained with bromine or biguanide, drain and refill it before installing FROG @ease. A spa previously using dichlor may be converted without draining only when the cyanuric acid level is below 80 ppm.

How can I confirm compatibility before ordering?

Confirm that your spa has flat, rectangular Simplicity filters and the updated cartridge openings. If you are uncertain, send Southern Leisure your spa’s model, serial number, and clear pictures of the filter compartment before ordering.
