Throat Irritation or Coughing

Often caused by an overdose of sanitizer (step #3). Don't forget that you TEST for step #3 weekly, but ONLY ADD when it's low. Some people forget this and add it weekly! The sanitizer is very stable and only needs to be added every 3-4 weeks! Solution: Use the spa and don't add more #3. The sanitizer will burn off eventually. If you're uncomfortable with this you'll need to drain the tub.


Another possible cause could be from overly soft water (low calcium hardness) With harder water, there's less iritation because less bubbles pop in the air and irritate your throat. Solution: Try adding twice the amount of waterline control (step #1) to add a shield to the surface of your water. Waterline control will coat the surface of the spa and makes the bubbles burst there, at the surface, instead of the air and in your face.
