How often do I need to change the water?

The frequency of water changes depends on how often the spa is used and how well the water is maintained with proper chemical treatment. 

We recommend changing your hot tub water at least once every 1–2 months.

You may be able to extend the time between water changes by keeping the spa covered when not in use, testing the water regularly to maintain proper chemical balance, running the pump for an adequate number of hours each day, keeping the filter cartridge clean, and replacing the cartridge when necessary.
