Start with what your system needs, then match the cartridge to it.

• Identify your setup: Floating sanitizer or in-line cycler?
• Water type: Hot tub, swim spa, or pool (above-ground or in-ground)?
• Sanitizer type: Your system may call for chlorine, bromine, or a mineral cartridge (some use a combo).
• Model and capacity: Check the model number on your floater/cycler and the water volume (gallons).
• Product details: On the product page, look for “compatible with” notes and pack size.

Using filters on this page and the item’s specifications can help you confirm fit. When in doubt, refer to your system manual before ordering.

A few simple steps can make swap-outs smoother and safer.

1. Prepare: Wear gloves, keep children and pets away, and avoid mixing with other chemicals.
2. Power down water movement: Turn off jets or circulation if your manufacturer advises.
3. Open the floater: Remove the old cartridge and keep it upright.
4. Insert the new cartridge: Don’t puncture or open it; twist or lock it in as directed by your system.
5. Set the dial: Adjust to the setting recommended for your water volume and usage.
6. Restart circulation and test: After circulating, use test strips to verify levels and fine-tune as needed.

Dispose of used cartridges per local guidelines. Results can vary based on water balance and bather load.

Service life depends on several factors rather than a single timeframe.

• Water volume and temperature: Larger or hotter water may use sanitizer faster.
• Usage: Frequent soaking or heavy pool use can shorten life.
• Circulation time: Longer pump run times may increase consumption.
• System design: Some floats include visual indicators when it’s time to replace.

Check the packaging or your system manual for model-specific guidance. Testing water regularly can help you decide when to swap cartridges—if levels don’t hold within the target range despite adjustments, a replacement may be due.

Each type serves a different role, and many systems specify one or a combination.

• Chlorine cartridges: Common in pools; provide a familiar sanitizer that maintains clear water when balanced correctly.
• Bromine cartridges: Often preferred in hot-water environments like hot tubs; bromine remains active at higher temperatures.
• Mineral cartridges: Add minerals that supplement your primary sanitizer and support clear water with routine care.

Use the type your floater or in-line cycler is designed for. Mixing non-specified types can affect water balance. Review the product page for “compatible with” notes and follow your system manual.

It’s best to match the cartridge to the exact system and water type.

• Check the label: Look for “hot tub,” “swim spa,” or “pool” compatibility and the supported gallon range.
• Follow system guidance: Some swim spas use spa-specific formulations even with higher volumes.
• Avoid interchange: Pool-only cartridges may not be suitable for hot-water environments or certain floaters/cyclers.
• Verify before buying: The product page’s specifications and your owner’s manual provide the most reliable fit information.

If you’re uncertain, consider ordering with convenient pickup or delivery options shown on the item page, and confirm compatibility before opening the packaging.
