Leisure Time Spa Minerals | Mineral Cartridge
Leisure Time Spa Minerals is an EPA-registered mineral purifier cartridge that delivers silver-ion sanitation to your spa water — and reduces your chlorine or bromine use by up to 50%. The cartridge releases a continuous, low-level stream of silver ions that destroy bacteria on contact, sharing the sanitation workload with your existing sanitizer program so you can dose dramatically less of it. One cartridge lasts up to 4 months in spas up to 600 gallons, fits inside or alongside your existing filter, and requires zero ongoing dosing or monitoring once installed. It's also a direct functional substitute for the FreshWater Silver Ion Cartridge — same chemistry, same fit, same purpose.
Mineral sanitation is the answer for owners who find traditional chlorine or bromine programs harsh. The silver ions in Spa Minerals are continuously released at low levels into the water, where they actively kill bacteria the same way silver has been used to purify water for centuries — long before modern sanitizers existed. Because the silver does part of the bacterial-control work, your chlorine or bromine residual doesn't have to work alone, which means you can run your sanitizer at the low end of its target range instead of the high end. The result is softer-feeling water, less chemical smell, gentler conditions on skin and eyes, and noticeably reduced sanitizer demand week over week.
This is a passive, set-and-forget product. Install the cartridge inside your filter (or in the filter well or skimmer tray depending on your spa model), and it works for up to 4 months without measuring, dosing, or testing. Replace at every drain-and-refill — typically the same cadence the rest of your spa maintenance follows. For owners chasing simpler water care and less chemical use, mineral cartridges are one of the highest-return upgrades available.

Leisure Time® Brand FAQs
Can I use Leisure Time products in any brand of hot tub?
Yes. Leisure Time spa chemicals are formulated to work safely in every major brand of residential hot tub, including Hot Spring, Caldera, Sundance, Jacuzzi, American Whirlpool, Bullfrog, and others. They're also compatible with every common spa shell material — acrylic, vinyl, fiberglass, rotomolded plastic, and stainless steel.
Will Leisure Time chemicals work with my sanitizer system?
The Leisure Time line is built for universal sanitizer compatibility. Products work with chlorine, bromine, ozone, mineral cartridge systems (silver/copper), biguanide systems (Baqua Spa, SoftSoak), and salt-generated chlorine systems like the FreshWater Salt System. Specific product labels will note any exceptions.
Can I mix Leisure Time with pool chemicals or other spa brands?
We don't recommend it. Spa chemistry is sensitive, and mixing brands can lead to unpredictable interactions — cloudiness, foam, sanitizer interference, or staining. Leisure Time products are tested as a complete system; using them together gives you the most predictable results and the simplest weekly routine.
How long do Leisure Time products last in storage?
Most Leisure Time chemicals have a shelf life of 1 to 3 years when stored properly. Keep all spa chemicals in their original containers, sealed tightly, in a cool, dry, well-ventilated area away from direct sunlight, freezing temperatures, and other chemicals. Liquid products are most sensitive to temperature; granular products are more shelf-stable but should still be kept dry.
Are Leisure Time products safe for septic systems and drainage?
Yes — when spa water is properly diluted and drained according to local regulations, Leisure Time chemicals at residual levels are safe for typical municipal drainage. For homes on septic systems, drain spa water gradually over your lawn or landscape rather than dumping it all into the septic field at once. Always check local ordinances before draining.
How often do I need to drain and refill my spa when using Leisure Time?
Industry guidance is to drain and refill every 3 to 4 months for a typical 400-gallon residential spa, regardless of which chemical brand you use. Heavy use, lots of bathers, or high-temperature soaking can shorten that interval; light use can extend it. Regular use of Leisure Time clarifiers, filter care, and stain & scale products helps maintain water quality between fills, but no chemical regimen replaces a fresh refill on schedule.
About Leisure Time®
For more than 40 years, Leisure Time® has built spa-specific water care chemistry trusted by hot tub manufacturers, dealers, and homeowners across North America. Where pool chemicals are formulated for tens of thousands of gallons of cool, lightly used water, Leisure Time® products are engineered for the opposite extreme: small water volumes, sustained high temperatures, heavy bather loads, and powerful jet circulation. That combination puts dramatically more stress on water chemistry than a swimming pool ever sees, and it's why generic pool chemicals don't perform reliably in a spa.
The Leisure Time® line covers the complete water care picture — sanitization, water balance, clarity, stain and scale prevention, filter care, and spa surface care — and every product is designed to work together as part of the Simple Spa Care Program. That means no surprise interactions, no guesswork about what's compatible with what, and a predictable weekly routine that takes minutes instead of hours. The full Leisure Time® system works with chlorine, bromine, ozone, mineral cartridge, and biguanide sanitizing programs, and is safe for every common spa shell material.
Leisure Time® is manufactured in the USA and is one of the most widely recommended spa chemical brands in the industry — used by Hot Spring, Caldera, Sundance, Jacuzzi, American Whirlpool, Bullfrog, and many other major spa manufacturers as the dealer-recommended water care solution for their tubs.
