      Rated 5 out of 5 by from Great Product I have used many products since having my hot tub for 3 years. Leisuretime Products are the best I have used. I was told to try the calcium boost and have found it adds to the proper mixture of chemicals need to balance your hot tub water for an comfortable, relaxing feeling.
