SILKY, SPARKLING WATER: Adds a noticeable softness and clarity to your water that you can feel the moment you step in. No more dry, itchy skin after a soak. LESS CHEMICALS, MORE SOAKING: By stabilizing pH and improving sanitizer efficiency, borates reduce the amount of chlorine or bromine you need to maintain clean, safe water.

EASY TO USE, BUILT TO LAST: Add 8 oz per 250 gallons with jets running. The 32 oz pouch gives you up to 4 treatments for a standard hot tub - that's up to 2 years of balanced water from one bag. Think Minerals Borates - The Easiest Way to Maintain Silky, Balanced Water in Your Hot Tub, Spa, or Cold Plunge
Hot tub pH constantly drifts because of sanitizers, balancers, airflow through jets, bather load, and temperature changes. Every time pH moves out of range, you're reaching for chemicals to correct it. Borates act as a natural pH buffer, locking your water in the ideal 7.2-7.8 range so you spend less time testing and adjusting.
Why do borates make water feel soft?
Borates reduce the surface tension of water, giving it a noticeably silky, smooth feel on your skin. No more dry or itchy skin after a soak. The water also takes on a sparkling clarity that you can see immediately.
How do borates help with sanitizer efficiency?
Chlorine and bromine are most effective at a neutral pH around 7.2-7.6. When pH drifts high, your sanitizer loses potency and you end up adding more. By keeping pH stable, borates help your existing sanitizer work harder, so you use less chlorine or bromine overall. This is especially important when using mineral systems, UV, or ozone to reduce chemical levels.
How long does one treatment last?
A single borate treatment lasts up to 6 months. Borates don't evaporate or get consumed by the sanitizer - they stay in solution until you drain and refill. The 32 oz pouch provides up to 4 treatments for a standard 250-gallon hot tub.
How to use:
With jets running, slowly add 8 oz of borate powder per 250 gallons of water. Balance alkalinity (80-120 ppm) and pH (7.4-7.8) first. Test for borates and adjust to around 50 ppm. That's it.
What's in it?
99.9% pure borate mineral sourced from volcanic soils. Single ingredient. No fillers, no additives, no artificial chemicals. Works with chlorine, bromine, mineral systems, saltwater, ozone, and UV sanitizers.
Compatible with all hot tub, spa, swim spa, jacuzzi, and cold plunge brands including Bullfrog, Hot Spring, Jacuzzi, Sundance, Caldera, Master Spas, and portable or inflatable models.
