Regular draining and refilling is a normal part of spa maintenance. Over time, the water absorbs and dissolves minerals, chemicals and other soluble material.  A Total Dissolved Solids (TDS) test helps determine if it's time to replace the spa water. High TDS can make the water look dull, become foamy and develop an odor.

How often a spa is drained and refilled depends on how often it is used. This simple formula can help:

Spa Gallons ÷ Daily Bathers ÷ 3 = Days Between Draining
Example: 300 gallons ÷ 2 daily bathers ÷ 3 = 50 days

Drain the water. Check owner's manual for information.

Clean the spa surfaces with SpaGuard Surface Cleaner.

Use SpaGuard Spa Polish to protect the finish. This cleaner is specifically formulated for use on the high-gloss acrylic surfaces used in many spas. It not only restores the shine, it protects the finish. However, it should not be used on spas with a non-shiny finish.

Refill the spa with fresh water.

Perform a water analysis.
