BALANCE THE TOTAL ALKALINITY (TA)
• The recommended Total Alkalinity (TA) for your tub water is 80-120 ppm.
• Total Alkalinity 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 buffer”. In other words, it’s a
measure of the ability of the water to resist changes in pH level.
• If the Total Alkalinity is too high, the pH level will tend to be high and may be difcult to bring down.
It can be lowered by using Cold Water Run Down.
• 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.
• When the Total Alkalinity is within the recommended range, proceed to the next step.
BALANCING THE PH
• We recommend a pH range for your water of 7.2-7.6.
• The pH level is the measure of acidity and alkalinity. Values above 7 are alkaline; those below 7 are
acidic. Maintaining the proper pH level is extremely important for:
• Optimizing the effectiveness of the sanitizer.
• Maintaining water that is comfortable for the user.
• Preventing equipment deterioration.
• If the water’s pH level is too low, the following may result:
• The sanitizer will dissipate rapidly.
• The water may become irritating to users.
• The equipment may corrode.
If the pH is too low, it can be increased by adding Jump to the water.
• If the pH level is too high, the following may result:
• The sanitizer will become less effective.
• Scale will form on the shell surface and the equipment.
• The water may become cloudy.
If the pH is too high, it can be decreased by adding Run Down to the 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.
• When the pH is within the recommended range, proceed to the nal step.
SANITIZE THE TUB
Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing unwanted
organisms from growing in the tub. 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 tub at the recommended level for each
type of sanitizer.
IMPORTANT: Sanitizers are acidic and will decrease the TA. Regular testing, removal and changing
of TA is extremely important with these products.
IMPORTANT: Always remove the oating dispenser while the tub is in use. Remove dispensers with
a plastic bucket and store out of reach of children until tub use has ended.
IMPORTANT!
Cold water oxidizer signicantly
reduces pH and TA. One hour after
adding cold water oxidizer test and
adjust TA and pH as needed.
