How often and in what manner you clean your hot tub will depend on two factors: how often the spa is used and the manufacturer.
- Test your hot tub water with test strips once or twice a week.
- Treat your hot tub water accordingly based on the readings from the test strips.
- Clean the filter every two weeks with water from the hose.
- Drain, clean, and fill the hot tub once every three to four months.
