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.
