Bullfrog Spas Simplicity XL SmartChlor System Kit

Easy, Self-Regulating Water Care for Larger Bullfrog Spas

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

The XL SmartChlor Cartridge contains 67% more SmartChlor than the regular-size cartridge, making it the preferred option for larger Bullfrog 8- and 9-size hot tubs. SmartChlor automatically releases sanitizer as the water needs it, maintaining a consistently low free-chlorine level with a reserve ready to respond when additional sanitation is required.

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

🧩 Compatibility & Fitment

This XL 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 8- and 9-size spas as the recommended XL 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 XL 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 XL system is not compatible with the triangular FROG @ease Classic cartridge holder used in Bullfrog X Series, STIL, and many older Bullfrog models. Confirm your filtration system, cartridge shape, spa model, and water capacity before ordering.

💬 Southern Leisure Says

This is the preferred starter kit for larger Bullfrog 8- and 9-size A Series and M Series spas equipped with Simplicity filtration. The XL SmartChlor Cartridge provides 67% more capacity than the regular-size cartridge, helping it keep up with the greater water volume and typical bather load of these larger hot tubs.

Before ordering, inspect your filter compartment carefully. Bullfrog Spas manufactured before 2024 may require the updated Bullfrog Simplicity Filter Housing 10-04669. Owners of smaller 5-, 6-, and 7-size Bullfrog Spas will typically want the regular-size Simplicity System Kit instead.

We strongly recommend using only FROG @ease Test Strips with this system. Standard test 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 XL 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 when replacing the SmartChlor Cartridge or approximately once per month.
• Do not use routine dichlor shock because cyanuric acid buildup can interfere with SmartChlor performance.
• Clean or replace the spa filters according to Bullfrog’s recommendations.
• Run the filtration system according to Bullfrog’s recommended schedule.
• Keep unused cartridges sealed 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 XL System Kit?

The XL System Kit is recommended primarily for Bullfrog 8- and 9-size A Series and M Series hot tubs equipped with the flat, rectangular Simplicity Filtration System. Smaller 5-, 6-, and 7-size models will generally use the regular-size system.

Will this System Kit 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 filtration systems using 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 XL System Kit?

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

What is the difference between regular and XL SmartChlor?

The XL cartridge contains 67% more SmartChlor than the regular-size cartridge. Regular cartridges are generally recommended for Bullfrog 5-, 6-, and 7-size spas, while XL cartridges are preferred for larger 8- and 9-size models.

How long does the XL SmartChlor Cartridge last?

It is recommended for up to approximately one month in Bullfrog 8- and 9-size spas. Actual cartridge life depends on water capacity, temperature, bather load, filtration, water balance, and cartridge setting.

How often should I replace the Mineral Cartridge?

Replace the Mineral Cartridge 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 the 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, use FROG Maintain or another compatible non-chlorine MPS shock when replacing the SmartChlor Cartridge or approximately once per month. 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 model, serial number, and clear pictures of the filter compartment before ordering.
