Effectiveness
based on pH Level
7.0 pH 27% 73%
7.2 pH 38% 62%
7.5 pH 50% 50%
8.0 pH 78% 21%
8.5 pH 90% 10%
Maintaining a Balanced pH level between 7.2pH and 7.6pH is extremely
important for:
• Optimizing the effectiveness of the sanitizer.
• Maintaining water that is comfortable for the user.
• Preventing equipment deterioration.
• Note: Salt systems naturally drive pH levels to increase, strive to achieve a
balanced pH level.
If the spa water’s pH level is too low, the following may result:
• The sanitizer will dissipate rapidly.
• The water may become irritation to spa users.
• The spa’s equipment may corrode reducing life expectancy.
Low pH can be raised by adding Arctic Pure, Adjust Up to the spa water.
If the pH level is too high, the following may result:
• The sanitizer is less effective.
• Scale will form on the spa shell surface and the equipment.
• High pH will cause calcium to precipitate (fall out of suspension).
• The water may become cloudy.
High pH can be lowered by adding Arctic Pure, Salt Water Balance to the spa
water.
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.
ORP Oxidation–Reduction Potential.
This is simply a measurement of the water’s ability to cleanse itself. ORP is
measured in millivolts (mV). Also refer FCL
Free Chlorine (FCL) FCL is the active form of chlorine that actually kills bacteria and algae (It is
a Sanitizer).
Sanitizer is extremely important for killing algae, bacteria and viruses, and
preventing unwanted organisms for 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.
Always maintain the sanitizer level in your spa within the recommended
range.
Also refer ORP
Chlorine Residual The actual level of chlorine in the water after the chlorine demand has
been satisfied.
