Did you know that in just 15 minutes 1 person will use up approximately 1 ppm of Chlorine or Bromine. In other words if you and 3 friends are in the hot tub for just 30 minutes you will use up 8 ppm of sanitizer. If you are keeping your tub at the suggested 3-5 ppm you can see how the demand is higher than the treatment supply. In order to make up for this difference you will want to give the hot tub a quick treatment with granular chlorine or bromine to ensure the level returns to a safe range of 3-5 ppm. If the tub is left even just a couple of hours without sanitizer it will result in cloudy, green and/or smelly water.
