When deciding how best to treat your hot tub, keep in mind that on average 1 person will use up 1ppm of Chlorine or Bromine in just 15 minutes.

If left with low sanitizer levels you could experience cloudy, green or stinky water. Come in and talk to our water care experts at Backyard Leisure for help in keeping your hot tub sparkling clear.
