Is Your Hot Tub Making You Miserable?

You bought a hot tub for relaxation, but instead you're dealing with:

  • Red, itchy skin and hot tub rash after every soak
  • Constant chemical monitoring — testing, adjusting, shocking, repeat
  • That lingering chlorine smell on your skin and hair
  • Monthly chemical costs that never seem to end

What if there was a better way?


Natural Spa: How It Works

Natural Spa is an enzyme-based treatment that replaces harsh chlorine and bromine with powerful natural enzymes that:

Break down contaminants naturally — body oils, lotions, organic matter
Keep water crystal clear without chemicals
Eliminate skin irritation — no more rash or chlorine smell
Reduce maintenance to minutes — add once every 2 months*

The result? Soft, luxurious water that's gentle on your skin and effortless to maintain.

Frequently Asked Questions

Q: How do I start using Natural Spa?
A: For existing tubs, we recommend cleaning your plumbing first with our Crystal Clean product (included in the 3/1 Conversion Kit) to remove chlorine/bromine buildup. For brand new tubs, simply add Natural Spa and enjoy.

Q: Will this work in saltwater hot tubs?
A: No. Though Natural Spa will work in a salt water tub for a short time, your salt water tub is actually generating chlorine that will eventually oxidize out the Natural Spa treatment. It might only last a week or two. We recommend that you consider not adding salt to your tub and turning off the chlorine generator.

Q: What if I have a smaller tub (under 300 gallons)?
A: Natural Spa can work in smaller tubs, but contaminants may remain visible for a period of time since smaller tubs don't dilute pollutants as well. If you only use the tub once or twice a week then a smaller tub may be fine with Natural Spa. However, we recommend Mineral Spa for tubs under 350 gallons since it is a stronger product and will clear the water faster than Natural Spa.

Q: Can I use this with my existing filter?
A: Yes. Natural Spa works with all standard hot tub filtration systems. We don't recommend the blue anti-microbial filters or the ceramic micro filters. These filters clog with just about any type of water treatment you use. We recommend the standard white paper pleated filters.

Q: What happens if I run out before 2 months?
A: Heavy usage may require more frequent additions. Simply add another dose when water clarity decreases. This is why we highly recommend going with our 3/1 Conversion Kit. The kit includes 3 bottles of Natural Spa and comes with the same money-back guarantee.
