Do I leave the filter in while cleaning?

  • Take the filter out of the housing but leave it in the spa water to soak clean. The water will flow faster with the filter out and the hot tub will run fine with or without the filter.

When do I use the Chlorine Free Shock?

  • If needed and as needed to get rid of odors or cloudy water. Use 1 tablespoon after use to eliminate odors, up to 4 tablespoons a day for up to 3 days to solve cloudy water issues

What should my pH be?

  • If you are on City Water your pH has been adjusted by your Municipal Water District; don’t add any chemicals to change it – ever.
  • If you are on well water adjust the pH to 6.5 to 7.5 before adding the bleach (or Chlorine) this one time, then do not adjust it again – ever.

Will it work with ozone?

  • We love ozone – it works well with our enzymes and minerals to eliminate odors and clear water quicker.

Can I use Hydrogen Peroxide?

  • Yes, it will do the same thing as Potassium Shock and is gentle on the skin – use ½ cup after use for odors, (brown bottle; 3%), up to 2 cups daily for 3 days for cloudy water.

The filter becomes coated with a tan film; is that normal?

  • The enzymes and minerals bond to contaminants in the water to make them larger so they will get caught in the filter; to be digested or removed when cleaning the filter. This is normal.

Will Natural Spa work in an inflatable tub?

  • Yes. Natural Spa will work in inflatable hot tubs and hot tubs with vinyl liners. However, Natural Spa contains enzymes that are naturally attracted to the oils in your vinyl liner. This will cause the sides to become very slippery and become an inconvenience for you.  A solution is to use a wash cloth to wipe the sides of the tub so the "slippery" film (Natural Spa) will dissolve back into the water every few days.

  • Best Solution! - Use Mineral Spa rather than Natural Spa in a hot tub with a vinyl liner such as an inflatable tub. Mineral Spa does not contain enzymes so it will not cause the liner to get slippery.  Mineral Spa Startup Kit

How much do I use?

  • Natural Spa: 4 ounces per 100 gallons of water.
  • Mineral Spa: 3 ounces per 100 gallons of water.
  • Crystal Clean: 4 ounces per 100 gallons of water.
  • Cascade: 3 ounces per 100 gallons of water.

The instructions say to use bleach or Chlorine – I thought this was a non- Chlorine system?

  • Nothing is as destructive as Chlorine, so we like to use it one time in new water to insure that the new water is as clean and sterile as possible.

Can I shock the water with Potassium Shock instead of bleach?

  • When filling with new water we recommend using bleach or Chlorine granules to insure the water is as clean as can be.
  • Chlorine-Free Shock is not as fast or as strong as bleach; if you insist on not using Chlorine add 2 ounces a day of Potassium Shock daily for 3 days after filling with new water.
  • Once you start using your spa use Chlorine-Free Shock, and then only if needed, to enjoy clean, clear water without harsh chemicals.

When do I put it in?

  • With fresh water put in the Natural Spa or Mineral Spa when the Chlorine smell is gone or the test strips show less than 1 ppm.
  • Add a bottle of Natural Spa after every 30 to 40 bather uses.
  • You can extend the life of Mineral Spa by adding 1/2 ounce every ten days or so.
  • Do not put any 2 products in at the same time – wait 4 hours or more between additions.

How do I test the water?

  • Use your eyes and your nose – the water will be clear and odor free when treated properly.

What else do I have to do?

  • Our Chlorine-Free Potassium Shock clears odors or hazy water after heavy use; add only if and as needed.
  • Hard water problems? Add an ounce of our Stain & Scale Control when filling.
  • Well water may need to have the pH adjusted when filling.
  • Enjoy your tub and tell your friends!

Can I buy these products at my spa store?

  • Although we have tried repeatedly to get our products into retail stores our low prices do not give the retailers the profits they desire, so very few will stock our products.
That's why we make it easy to buy our products on-line and ship it directly to you.

    Will it work with Jacuzzi or Sundance Clearview UV systems?

    • Mineral Spa works with UV, but in many cases the water gets cloudy with the Natural Spa.
    • Both products work well with ozone.

    What’s the difference between Natural Spa and Mineral Spa?

    • Mineral Spa detoxes the body like bathing in a natural volcanic hot spring. It lasts for up to 8 months in a 500 gallon tub and clears the water quicker in small spas or high use tubs. Works in aquariums to extend life of water.
    • Natural Spa has a little less maintenance, lower cost and leaves your skin feeling silky soft. Not for use in aquariums.

    How do I clean my tub?

    • It’s always a good idea to clean your tub before you drain – add 4 ounces Cascade for every 100 gallons of water in the spa, (or your favorite automatic dish-washing detergent).
    • Run the jets on high a few times.
    • You can add 4 ounces of bleach for every 100 gallons of water to get it really clean.
    • Drain after 4 hours or the next day.
    • It doesn’t hurt a thing if you leave it in for a few days.

    Will it hurt my tub?

    No! Unlike Chlorine or Bromine the water in tubs treated with our natural products is not caustic or corrosive; it is good for your skin, good for your hot tub, and good for the plants in your garden where you drain your spa.

    Our products do not plug up filters like Bromine or Biguanide, do not oxidize the plastic in you tub like traditional chemicals, (making it chalky and brittle), or attack metals.

    Your tub will work better and last longer with these products.

    What do I have to do to switch?

    It’s easy! If your using Chlorine and your water is fresh and clear all you need to do is let the Chlorine level drop to zero and then pour in the Natural Spa or Mineral Spa, (whichever you choose), and you’re done!

    If the hot tub used to have Bromine in it, or if it has signs of hard water scale or metal stains then you need to clean the tub first; just add Crystal Clean to the old water that is in your tub and run it a few times a day for the next few days, then drain it – now your tub is as clean as it can be and ready for a natural product.

    If your water has Biguanide in it, (BaquaSpa, Soft Spa, Leisure Time “Free”), drain that water before using the Crystal Clean.

    Can I use the tub with Crystal Clean in it?

    • Normally yes! Crystal Clean is made of Citric acid and Sulfamic acid - both organic acids - which create a therapeutic bath that leaves your skin squeaky clean and feeling rejuvenated – it’s like an expensive skin therapy session at your local health spa.
    • If you got a rash from the Bromine then do not use the tub while cleaning it. As the old chemical build-up is dissolved by the cleaning process these harsh chemicals are now in your water and may irritate your skin again.

    Love your Natural Spa product - FAQ About well water

    Recently a customer asked me the following question about well water and I thought some of you may benefit from this info as well.

    Love your Natural Spa product. I just need a recommendation for a well water filter when refilling spa with a garden hose. Thanks Ted B.

    I recommend adding Chlorine bleach to new water to destroy unwanted contaminants, no matter what they are.

    If you do not want to use Chlorine, or if it’s not working on your well water (heavy particulates, high pH, etc.) then a filter that removes heavy metals and organics is the only practical solution.

    We have the Guard n’ Grow filter that does this – treats 25,000 gallons and sells for $89.95.

    I have seen de-ionizing resin filters that will treat three to five hundred gallons that sell for $59.95 or so.

    The $15 filters are just carbon and sediment filters that only remove solids (and pesticides – hopefully, you don’t have pesticides in your well) so they are essentially useless.

    If you want one of these nice filters, let me know.
    Thanks, Cal



    Natural Spa Instructions
    Water Discoloration and Cloudiness

    "We are experiencing water discoloration and cloudiness. Yesterday I cleaned the filters, they did appear to be yellowing and the yellowing rinsed right off, but again this morning the spa looks yellow and cloudy.   I ran the jets for a few hours and it appears to be clearing, but a yellowish/brown tint is still there.  I see that I can use potassium shock, and I have added one capful, but am hesitant due to the rashes.  Will the Potassium shock be an ongoing addition or just until the cloudiness/discoloration dissipates.  Also, does the usage of potassium affect the quality/efficiency of mineral spa/ natural spa in any way? Your recommendations are appreciated." - Carol 
    The Potassium Shock does not affect the quality of the enzymes or minerals, though in your case I would recommend you use Hydrogen Peroxide as a Shock/Oxidizer to insure no skin irritation.
    The color in your water is the normal function of the minerals as they bond to contaminants in the water and form micro-clusters to be filtered out, so always remove and rinse the filter of any accumulation before adding Shock so you are not dissolving these contaminants back into the water.
    If a film develops on the walls of the spa it is, again, the agglomerated mineral/contaminants. Just brush it back into the water so it will be filtered out.
    Once the minerals have removed the colored contaminants the water will clear and the color will be back to normal.
    Keep in mind that there are now more minerals in your water, so a hint of color may remain, and is quite normal. Only chemically bleached water is the bright, clear blue that we have become accustomed to; in its natural state water always has a hue that reflects its mineral content.
    After the water clears, which may take a few days, regular additions of the Natural Spa (1 ounce) and Mineral Spa (1/2 ounce the next day) will keep it healthy and clean. It may get a little hazy after adding the Natural Spa (after every 6 bather uses) but will be nice and clear again in a day or two.

    Brown Film on Walls

    "I have used your spa products since the summer. I recently emptied the water and used crystal clean before draining. I have been adding scale control because I am developing a brown scum and it feels slimy along the walls of the hot tub. This is new as it didn't do that all summer - any suggestions? I really don't want to drain it all over again." - Mary



    The brown scum is due to static cling attracting the oils and minerals in the water to the spa shell. Brush it away with the filter pumps running so it gets into the filter, then rinse the filter clean.

    We recommend 6 to 8 hours of filter time daily.

    Chlorine-Free Shock Oxidizer will break the static cling and clear the film, but that is a chemical solution that destroys the oils rather than letting these oils and minerals go into the filter to be removed naturally.

    Also, when you drain at the end of the season we recommend you use automatic dishwashing detergent and bleach to clean your spa (4 ounces of each for every 100 gallons of water) instead of the Crystal Clean. The detergent and bleach do a better job on oily residues (our enzyme formula does have a coconut oil base). If you have metal stains or scale then you would use the Crystal Clean.


    Can you recommend any Essential Oils that we can use in our hot tub?

    "Can you recommend any Essential Oils that we can use in our hot tub, like Eucalyptus??  We currently use your natural chemicals...the Mineral. Love it so far. 450 gal tub. 9’x9’. Also, can you recommend a light-weight, durable, and eco-friendly spa cover. I am not pleased with 5” foam covers that fill with water, get heavy and last for only 4 years."

    Thanks - Dynasty 


    The essential oils I have used dissolve in water and so work well with our minerals – I have had no unwanted side effects. I usually buy whatever is on the shelf at our local organic food market and give it a try. There are so many companies that sell these products at high prices with great stories, and I think they are just charging for the story.

    I have tried oils mixed with salts, but had better luck with the artificial fragrances for longevity. So use the oils by themselves for the best effect.

    About the cover – I would look into a “snow load” cover for your area. They cost more but should last a very long time. Some are aluminum and I have heard of one that’s inflatable. Don’t have any specifics, but that’s the direction I would go. You are so right about the foam – even here in moderate weather they just don’t last that long and soak up water long before they even get weathered badly.

    Good luck in your search.
