Spa Maintenance

You should drain your spa water every 30 - 90 days depending on frequency of use.

As you care for your spa, please keep in mind that a spa is not merely a small swimming pool. Due to the higher water temperature and smaller amount of water in a spa, four people in a spa is equivalent to 300 individuals in a backyard swimming pool. For this reason, it is very important to maintain your spa to ensure it is clean and properly sanitized.

Identify which of the three sanitizing systems you are using and follow the program below:

Sanitizing System 1: Rendézvous™ Enhance®/Activate™

Every day of the 3-Day Program

  • Test pH, total alkalinity and sanitizer levels with HTH® or GLB® 4-Way Test Strips and adjust levels as necessary.
  • After each spa use, add 60 g of Rendézvous™ Activate™ Granular per 1,000 L of water.
