If the pH is too high, it can be decreased by adding Arctic Pure
5. It is important to check the pH on a regular basis. The pH will be affected by the bather load,
the addition of new water, the addition of various chemicals, and the type of sanitizer used.
6. When the pH is within the recommended range, proceed to the final step.
Calcium Hardness (CH)
1. Most spa manufacturers recommend a Calcium Hardness (CH) level for your spa of 150-200
ppm. However, we do not recommend adding calcium to your spa if your spa water is above
100 ppm, or if your incoming water has a very low level of calcium hardness.
2. Calcium Hardness is a measure of the total amount of dissolved calcium in the water. It is
believed that calcium helps control the corrosive nature of water. Calcium has a tendency to
precipitate (fall out of suspension) in high temperatures and high pH levels.
Warning: When calcium falls out of suspension it can collect on the heater and pump, and
shorten their life.
3. Any natural corrosiveness in the water can be combatted by maintaining a slightly higher Total
Alkalinity Level.
Sanitize the Spa
Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing unwanted or-
ganisms from growing in the spa. At the same time, you don't want too high a sanitizer level, or it can
irritate your skin, lungs and eyes.
1. Always maintain the sanitizer level in your spa at the recommended level for each type of
sanitizer.
2. We recommend the following sanitizers:
Chlorine System:
• Arctic Pure Chlorine Tablets
®
• Arctic Pure Refresh
®
• Arctic Pure Boost
®
Bromine System:
• Arctic Pure Brominating Tablets
®
• Arctic Pure ® Refresh
• Arctic Pure Peak Boost
®
Important: Sanitizers are acidic and will decrease the Total Alkalinity. Regular testing and balancing of
TA is extremely important with these products.
Important: Always remove the floating dispenser while the spa is in use. Remove dispensers with a
plastic bucket (keeping submerged) and store out of reach of children until spa use has ended.
Using Chlorine System
CAUTION: The use of personal protective equipment (rubber/latex/vinyl gloves, eye protection) is
recommended while handling the dispenser or the pucks.
Adjust Down to the spa water.
