Spa Sentry | 46238BIO

1. Drain the water out of the spa. Once done, clean the spas surfaces with SpaGuard Surface Cleaner and clean the filter with SpaGuard Filter Cleaner & Degreaser.
2. Refill your spa with fresh water. Important: The heater should be off before the addition of Spa Sentry. The heater should remain off until all cloudiness has been cleared by filtration.
3. Add the Spa Sentry solution with the water circulating.
4. If your fill water has calcium hardness less than 150 ppm (195 ppm total hardness) add 1 quart (1 bottle) of Spa Sentry per 300 to 500 gallons of spa water.
5. If dissolved calcium is present, the water-softening action of Spa Sentry will precipitate the calcium, allowing the filter to remove it. Please note, the water may cloud when the product is added indicating that Spa Sentry is working to remove excess calcium. If the water continues to be cloudy allow the circulation pump to run for 24 hours.
6. If the water is still cloudy clean and degreases the filter using SpaGuard filter cleaner.
