Bullfrog Spas Simplicity XL SmartChlor Replacement Cartridges – 3-Pack

XL SmartChlor Replacement Cartridges for Larger Bullfrog Spas

Keep your Bullfrog Spa’s FROG® @ease® Simplicity® water-care system operating with this convenient three-pack of XL SmartChlor® replacement cartridges. Designed for larger compatible Bullfrog Spas, each cartridge automatically releases sanitizer as the water needs it—helping maintain clean, clear water with less measuring, handling, and daily adjustment.

XL cartridges contain 67% more SmartChlor than regular-size cartridges, making them the preferred option for Bullfrog 8- and 9-size hot tubs. SmartChlor maintains a consistently low free-chlorine level while creating a reserve that activates when additional sanitation is needed.

This package contains three individually sealed XL SmartChlor cartridges. The blue FROG @ease Mineral Cartridge and filter housing are sold separately.

🧩 Compatibility & Fitment

These XL SmartChlor cartridges are designed for Bullfrog Spas equipped with the Simplicity Filtration System and updated cartridge housing. Compatible applications include:

• Bullfrog Spas M Series models with Simplicity filtration
• 2023 and newer Bullfrog Spas A Series models with Simplicity filtration
• Updated Bullfrog Simplicity Filter Housing, part number 10-04669
• 8- and 9-size M Series and A Series spas as the recommended XL application

Important: Bullfrog Spas manufactured before 2024 may require the updated Simplicity Filter Housing, part number 10-04669. This retrofittable housing accepts both regular-size and XL FROG @ease Simplicity cartridges and is sold separately.

These XL cartridges are not designed for the Classic cartridge holder used in Bullfrog X Series, STIL, or most Bullfrog Spas manufactured before 2023. Confirm your filtration system, cartridge housing, and recommended cartridge size before ordering.

📋 How to Use

1. Confirm that your Bullfrog Spa uses the Simplicity Filtration System and updated cartridge housing.
2. Test and balance the spa’s total alkalinity, pH, and total hardness before installing the cartridge.
3. Remove the depleted gray SmartChlor cartridge from the cartridge holder.
4. Set the dial on the new XL cartridge according to the setting recommended for your Bullfrog Spa model.
5. Insert the new cartridge into the holder alongside the blue FROG @ease Mineral Cartridge.
6. Reinstall the cartridge holder in the Simplicity filter housing.
7. Test the water regularly using FROG @ease Test Strips.
8. Replace the SmartChlor cartridge when the Out Indicator appears or the cartridge is depleted.

Each XL cartridge is recommended for up to approximately one month of use in 8- and 9-size spas. Actual cartridge life varies based on spa size, water temperature, bather load, filtration, water balance, and dial setting.

💬 Southern Leisure Says

The XL SmartChlor cartridge is the preferred option for larger 8- and 9-size Bullfrog M Series and A Series spas. Its increased capacity helps the cartridge keep up with the greater water volume and typical bather load of these larger hot tubs.

Before ordering, check both your spa model and filter housing. If your spa has the previous Simplicity housing, you may need to install the updated Bullfrog Simplicity Filter Housing 10-04669 before using these cartridges. Owners of smaller 5-, 6-, and 7-size spas will typically want the regular-size Simplicity SmartChlor cartridge instead.

🧼 Care & Maintenance

• Keep unused cartridges sealed in their original packaging.
• Store cartridges in a cool, dry, well-ventilated location away from heat and direct sunlight.
• Use FROG @ease Test Strips because standard test strips cannot accurately interpret the SmartChlor reserve.
• Keep total alkalinity, pH, and total hardness within the recommended ranges.
• Replace the blue FROG Mineral Cartridge every four months or whenever the spa is drained and refilled.
• Shock approximately once per month using FROG Maintain or another compatible non-chlorine MPS shock.
• Do not use dichlor shock because cyanuric acid buildup can reduce SmartChlor’s effectiveness.
• Always follow the instructions provided with your FROG @ease system and water-care products.

❓ Frequently Asked Questions

Will these XL cartridges fit every Bullfrog Spa?

No. These cartridges require the Bullfrog Simplicity Filtration System and updated cartridge housing. They are intended primarily for larger 8- and 9-size M Series and 2023-or-newer A Series spas. They do not fit the Bullfrog Classic cartridge holder.

What is the difference between regular and XL SmartChlor cartridges?

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

How long does each XL cartridge last?

Each XL cartridge is recommended for up to approximately one month in 8- and 9-size spas. Cartridge life varies based on spa size, bather load, water temperature, filtration, water balance, and dial setting.

Does this 3-pack include the blue Mineral Cartridge?

No. This package contains three gray XL SmartChlor replacement cartridges only. The blue FROG Mineral Cartridge is sold separately and should be replaced every four months or whenever the spa is drained and refilled.

Why should I use FROG @ease Test Strips?

SmartChlor creates a chlorine reserve that standard test strips may display as elevated total chlorine. FROG @ease Test Strips are designed specifically for the system and include an Out Indicator that helps determine when the SmartChlor cartridge needs replacement.

Do I still need to shock my hot tub?

Yes, but normally only about once per month. Use FROG Maintain or another compatible non-chlorine MPS shock. Do not use dichlor shock because cyanuric acid buildup can interfere with SmartChlor performance.

How can I tell whether I have the correct filter housing?

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

Check that your spa uses the flat, rectangular Simplicity filter system rather than cylindrical filters. Contact Southern Leisure with your spa model, serial number, and a picture of the filter compartment if you need help confirming fitment.

Is filter housing 10-04669 included with this 3-pack?

No. This product contains three XL SmartChlor replacement cartridges only. The Bullfrog Simplicity Filter Housing 10-04669 is sold separately.
