Spa Care Simple Start Up

To get your spa off to the right start, follow these three steps:

  1. Waterline Control
  2. Shock
  3. Sanitizer - with Stain & Scale Control

Balance - Fill spa, take a water sample for analysis, and balance water according to BaquaSpa recommendations. Remember to chemically clean your filter.


  • Add BaquaSpa Waterline Control (prior to adding BaquaSpa Sanitizer with Stain & Scale Control).
  • Add BaquaSpa Shock.
  • Circulate the water on high speed for 15 minutes, with blowers off - do no inject air.
  • Add BaquaSpa Sanitizer with Stain & Scale Control and circulate for 15 minutes.

Test - Us a BaquaSpa Test Strip to test BaquaSpa Sanitizer with Stain & Scale Control level. If the level is between 30 and 50 ppm, your spa is ready to use.

All measurements are in liquid ounces.

Note: Chemicals can be added to either cold or hot water. If the water temperature is cold, the addition of BaquaSpa Waterline Control may cause a temporary cloudy condition. Once the temperature reaches normal spa levels (98-104 degrees F), the cloudiness will disappear. BaquaSpa Sanitizer with Stain & Scale Control will react with some impurities in the water to form insoluble particles. Within the small environment of a spa, these insolubles may be deposited on the spa shell, especially at initial start-up. This "bathtub ring" will vary depending on the quality of the fill water, and usually appears as yellow/brown, sticky deposits. Wipe affected areas clean with BaquaSpa Surface Cleaner. When used properly, BaquaSpa Waterline Control will eliminate deposits from forming on the spa shell.

Note: The measuring cup should be thoroughly rinsed after each use. The outside of the BaquaSpa Shock bottle should be wiped with a clean, damp cloth after use to remove any liquid that may have dripped into it.
