Check the chemical levels in the hot tub weekly, and add chemicals as necessary at that time. Test for chlorine, total alkalinity, hardness and pH. Maintaining the appropriate balance of chemicals is important to water safety and protection of the hot tub’s heat components.
Other important maintenance tasks include changing the water on a bi-monthly schedule. With proper chemical maintenance, it may only be necessary to change the water every 12 weeks. Cleaning the filter weekly or more often during periods of heavy use allows the heater and pump to work more efficiently. In addition, cleaning the shell of the tub during water changes helps keep the water clean and safe for use.
