Why You Need a Conversion Kit

Chlorine and bromine leave behind residue inside your plumbing. If you switch to natural treatment without cleaning that buildup, you’ll fight cloudy water and inconsistent results.

Both conversion kits include Crystal Clean and non-chlorine shock to reset your tub the right way.

Choose Your Natural Conversion Kit

We offer two product lines that will work great in the majority of hot tubs.

Enzyme-Based

Natural Spa

The Original Organic Hot Tub Treatment (Since 1995)

Natural Spa is the gentle, effective alternative to chlorine and bromine. Our enzyme-based formula breaks down oils, lotions, and organic contaminants so your water stays clear, soft, and comfortable without harsh chemicals.

How It Works: Natural Spa uses powerful natural enzymes to digest contaminants that normally cloud your water. Instead of masking problems with chemicals, it removes the source — keeping your water clean, clear, and comfortable.

Perfect For

  • Acrylic or fiberglass hot tubs
  • Tubs 300–500 gallons (best at 350+)
  • Sensitive skin or chemical sensitivities
  • Anyone wanting an affordable, natural system

Volcanic extracted mineral based

Mineral Spa

The Premium Backyard Hot Spring Hot Tub Treatment

Mineral Spa gives your water the same silky, soothing feel you’d expect from a natural hot spring. Our volcanic mineral formula clears water fast, works in any tub, and lasts up to 8 months with almost no maintenance.

How It Works

Mineral Spa uses natural volcanic minerals to neutralize contaminants. Oils, lotions, and dissolved particles clump together and get trapped in your filter, leaving your water clean, clear, and luxuriously soft.

Perfect For

  • Works in all tubs including Cedar or vinyl-lined inflatable hot tubs
  • All tubs from 100 to 600 gallons
  • Heavy-use spas
  • Anyone wanting the premium “hot spring” experience
  • Users who want the longest-lasting natural treatment
  • User wanting a natural healing hot spring in their backyard.
