TERM DEFINITION
Onzen™ An all-natural, salt-water softening and maintenance system.
Onzen™ Output Electrode Three plate platinum-iridium Titanium electrode - equipped salt cell converts the
saltwater solution to sanitizer, and as this solution reverts back to its natural form
(salt) after sanitizing. Unless large volumes of water are added to the spa you
never have to add more salt. The Three plate electrode plastic outer casing is
black in color.
Note: When the Onzen System has activated the Output Electrode to generate
sanitizer, the electrode gives o󰀨 smoke e󰀨ect.

Calcium Hardness (CH) Calcium Hardness is a measure of the total amount of dissolved calcium salts in
the water.
CH helps determine how scaling or corrosive the water is. It is believed that
calcium helps control the corrosive nature of water.
Calcium has two major problems in Hot Water Chemistry:
1. CH has a tendency to precipitate (fall out of suspension in high tempera
-
tures, ,
where pH is above 7.8ppm)
2. High pH will cause calcium to precipitate. The problem with calcium falling
out of suspension is that it collects on the heater and pump, and shortens
their life. High pH also reduces the life of the Onzen Output Electrode.
Any natural corrosiveness in the water can be combated by maintaining a slightly
higher Total Alkalinity Level.
Alkalinity
Total Alkalinity (TA)
A measure of how stable the pH is (a measure of the total levels of carbonates,
bicarbonates, hydroxides, and other alkaline substances in the water).
TA is referred to as the water’s “”pH bu󰀨er””. In other words, it’s a measure of the
ability of the water to resist changes in pH level.
If the TA is too low, the pH level will uctuate widely from high to low. Fluctuations
in pH can cause corrosion or scaling of the spa components.
Low TA can be corrected by adding Arctic Pure, Perfect Balance to the spa water.
If the Total Alkalinity is too high, the water will be more susceptible to scale and
high pH. High pH may be di󰀩cult to bring down.
Note: Salt systems naturally drive pH levels to increase.
High TA can be lowered by adding Arctic Pure Salt Water Balance to the spa
water.
Once the TA is Balanced, it normally remains stable, although some sanitizers,
and the addition of more water with a high or low alkalinity will raise or lower the
TA reading of the water.
