Water Maintenance
It’s important to have clean water. Water maintenance is one of the least understood, but very important
areas of spa ownership. Your dealer can guide you through the process of achieving and maintaining 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 lter 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 viruses can grow quickly in
under sanitized 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), Calcium Hardness
(CH) 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 eciency.
For Onzen System: Please refer to your Onzen User Guide for direction in water
maintenance. (Pg.81)
For Spa Boy System: Please refer to your Spa Boy Owners manual for directions
in water maintenance. (Pg.54)
Methods For Testing The Spa Water
Accurate water testing and analysis are an important part of eectively maintaining your spa water. To follow
the Arctic Spas
®
recommended program, you must have the ability to test for:
• Total Alkalinity (TA)
• Calcium Hardness (CH)
• pH
• Sanitizer
Although reagent liquid 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.Very high sanitizer levels will also render test strips
unreliable.
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 30-45 cm (12” - 18”) below the water surface.
