There are 2 primary components that affect spa water quality:

1. Sanitizer, either bromine or chlorine residual
2. pH

When both are within their recommended ranges:

• Water is comfortable, protected and clear.
• Sanitizers and "shock products" work efficiently.
• Spa surfaces and equipment are protected.

Maintain bromine or chlorine residual within recommended range:
Bromine residual = 2 - 6 ppm
Chlorine residual =1 - 3 ppm

(If spa is equipped with an ozone generator, chlorine or bromine residual can be close to the lower end of their ranges.)

Maintain the pH between 7.4 - 7.6. In this range bathers are comfortable, the spa surface and equipment are protected, and the sanitizers perform efficiently.

Add SpaGuard^® Spa Sentry™ to hold the pH in its optimum range. pH is THE most important aspect of spa water quality. However, maintaining the proper pH can be challenging. The heated, aerated water, combined with heavy bather loads, can cause the pH to change quickly, unless a means for buffering these changes is present. That's where SpaGuard Spa Sentry comes in. Spa Sentry is formulated to "watch over" the pH and protect the water from pH changes.

Test sanitizer and pH level several times a week with the 4-way test strips. These strips provide quick, easy and accurate readings. The test process is easy. Follow the label instructions. Simply dip and read.

  A complete water analysis is recommended every 4-6 weeks. In addition to testing the pH and sanitizer, this analysis will measure the water's total alkalinity, calcium hardness, iron, copper, manganese and total dissolved solids.
