It’s important to have clean water. Water maintenance is one of the least understood, yet most impor-
tant area of spa ownership. Your dealer can guide you through the process of achieving and maintain-
ing perfect water in your spa, given your local conditions. Your program will depend on your water’s
mineral content, how often you use your spa, and how many people use it. Here is our suggested
step-by-step program:
General Information
There are three fundamental areas of water maintenance. They are (1) Water Filtration, (2) Water
Sanitation, and (3) Chemical Balance/pH Control.
Although your spa’s filter system is working several hours a day to remove particles from your water,
it does not remove bacteria or viruses. Water sanitation is the responsibility of the spa owner. It can
be achieved through the regular and periodic (daily, if necessary) addition of an approved sanitizer.
The sanitizer will chemically control the bacteria and viruses present in the spa water. Bacteria and vi-
ruses can grow quickly in undersanitized spa water. The water’s chemical balance and pH control are
also the responsibility of the spa owner. You will have to add chemicals to maintain proper levels of
Total Alkalinity (TA) and pH. Proper water balance and pH control will minimize scale buildup and
corrosion of metals, extend the life of the spa, and allow the sanitizer to work at maximum efficiency.
Methods For Testing the Spa Water
Accurate water testing and analysis are an important part of effectively maintaining your spa water.
To follow the Coyote Spas™ recommended program, you must have the ability to test for:
• Total Alkalinity (TA)
• pH
• Sanitizer
Although reagent test kits provide the highest level of accuracy, test strips are the most convenient
testing method used by many spa owners. Keep in mind that test strips are susceptible to heat and
moisture contamination, which will result in inaccurate readings.
IMPORTANT: Always read and carefully follow the directions included with the test kit or test
strips to ensure the accuracy of the test results.
Hints for Successful Water Testing
When using the reagent test kit:
• Always take water samples 12-18 inches (30- 45 cm) below the water surface.
• Rinse the test cells before and after each use.
