Low TA - Can be raised by adding Arctic Pure, Perfect Balance to spa water. High TA - Can be
lowered by adding Arctic Pure Salt Water Balance to spa water.
Salt systems naturally drive pH levels to increase, strive to achieve a Low pH level 7.2. pH
must not exceed 7.6.
Low pH - Can be raised by adding Arctic Pure, Adjust Up to the spa water.
High pH - Can be lowered by adding Arctic Pure Salt Water Balance to spa water.
Low FCL - Can be raised by adding Arctic Pure, Boost and or turning Onzen Cycle Duration
(Chlorine Production On) Level up.
High FCL - Can be lowered by:
• Natural cause over a few days.
• Turning Onzen Cycle Duration (Chlorine Production On) down.
• Adding Arctic Pure, X-it.
The above is dependent on FCL level, spa usage and bather load.
High CH - lower with a stain & scale controller such as Arctic Pure, Best Defence, to help hold
Calcium in suspension.
Once Sodium Chloride reading is in the ideal 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 target range.
High Sodium Chloride - add water.

Go into low level settings and adjust Onzen Cycle Duration (Chlorine Production On) accord-
ingly.
Adjust to suit spa usage and bather load.
