How often should I change my water?

60 to 90 days is typically recommended by the spa industry. Using the Nova Spa system, the Conditioner should last 90 days. If your spa water is clear and cleans up quickly using the water clarifier or shock, just add a new bottle of Nova Spa Water Conditioner. Depending upon spa usage and water quality preference, some customers may need to change their water only once a year. Most customers will change their water about every 6 months.
