Spa pure chlorine granules used in hot tubs. This is the 2# container but it is also available in 5# pails.
We recommend 2oz of chlorine 2x per week for most spas but always test your hot tub water with chlorine test strips for proper balance before use. We recommend keeping your chlorine level between 3 and 5 ppm. If you have alternative sanitizers like ozone, UV , or mineral sanitation you can reduce that recommendation.
Whenever you add chlorine to your hot tub run the jets on high speed for 10 minutes. It is then very important to stay out of your spa for at least 2 hours as your chlorine levels will be elevated too high for use. Contains 97% Sodium Dichlor
