Calcium Hardness (CH)
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.
Warning:
When calcium falls out of suspension it can collect on the heater and pump, and
shorten their life.
Sanitize the Spa
Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing unwanted organisms
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.
