Maintenance Action to Adjust/Correct
As Salt systems naturally drive pH levels upwards, it is most critical to the performance/life of
the salt system to maintain the pH within the target range.
High pH reduces the effectiveness of chlorine.
• pH level of 7.2 makes chlorine 62% effective (38% loss of effectiveness).
• pH level of 7.5 makes chlorine 50% effective (50% loss of effectiveness).
• pH level of 8 makes chlorine 21% effective (79% loss of effectiveness).
Therefore, high pH causes your Spa Boy system to produce more chlorine thus increasing pH
even higher and reducing the effectiveness of chlorine even further.
Strive to achieve a Low pH level 7.2. pH must not exceed 7.6. If pH is slightly below 7.0ppm do
not adjust.
Low pH - Can be raised by adding Arctic Pure Salt Water Balance, Adjust Up to the spa water.
High pH - Can be lowered by adding Arctic Pure Salt Water Balance, Adjust Down to spa water.
545-550 mV is the Optimum Range factory default setting.
The user may adjust higher if preferred by contacting their dealer to have it adjusted. Spa Boy
will strive to maintain ORP within the Optimum Range.
Depending on the water chemistry which will be affected by bather load and spa usage, at
times the ORP value will overshoot or undershoot the Optimum Range.
Once Sodium Chloride reading is in the target range salt concentration will only change if
water is splashed or drained out. Do not add salt unless this test confirms the level is below the
chemical acceptable range.
High Sodium Chloride - add water above 2500ppm
Low Sodium Chloride - add salt below 2000ppm
At a minimum 1 capful per week should be added for a spa and 2 caps full for an AWP. This
amount can be reduced if your spa is equipment with an Arctic Spas OZONE System.
