Water Quality and Water Chemistry

Maintaining water quality and water chemistry in your spa is extremely important and should be a regular part of your spa

maintenance program, as a neglected spa can be a breeding place for dangerous bacteria.

The water quality of your spa is maintained by a combination of filtration and chemistry.  The spa’s integral filter system

helps maintain the water cleanliness and clarity by trapping most solid materials such as body oils, hair, and other debris
resulting from normal use.  However, the most important part of maintaining water chemistry is keeping the proper level of
disinfectant in the water at all times.  This is accomplished by adding chlorine or bromine to the water, which will control
particles too small to be trapped by the filter, such as bacteria and algae, and will oxidize any organic materials.  Follow
instructions provided here and with water quality products for the health and safety of spa users, as well as to make your
spa bathing as enjoyable as possible.

Filtration

The filtration system of your spa will keep your water

clear and clean if used properly.  We recommend that you
run your filter system for at least two hours each day.  The
filter cartridge elements will trap most solid materials and
debris in the water. However, the presence of materials
such as body oils or other particles which are too small to
be captured in the filters may bring about various undesir-
able water quality conditions.  These conditions can be
corrected with the use of spa treatment chemicals which
are available from your Jacuzzi Whirlpool Bath dealer.
Such conditions include the following:

Foaming:

  A defoamer is available to minimize foaming

of the water.  This condition is usually caused by the
addition of soaps or oils, or other fatty substances to the spa
water.  The interaction of these with hot water, especially at
high pH (more alkali) will cause the water to foam.  (See
Water Quality Definitions.)

Oil Film or Cloudy Water:

  Add clarifier to congeal oil

film on the water surface into globules sufficiently large to
be trapped by the system’s filter.  Cloudiness is caused by
particles that are too small to be trapped in the filter and is
also due to the presence of human body oils, lotions, and
cosmetics.  After adding clarifiers, these materials will
accumulate on the filter element and clog its pores.  The
addition of clarifier will make the water clearer, but clogged
filters must be cleaned as prescribed under the section
entitled “Filter Maintenance” in this manual.

Hard Water: 

 Add a de-mineralizer to break down or

de-ionize mineral particles present in the spa water.

Follow the “Filter Maintenance” procedure described in

this manual to ensure optimum performance of your spa’s
filtration system.

Water Chemistry

You can ensure better water chemistry by testing your

spa water every day and adjusting the chemical balance
frequently.  Obtain a water quality test kit, designed espe-

cially for spas.  The test kit must be of the type which allows
you to test for the disinfectant (chlorine) level, pH, and total
alkalinity.  Make sure,  that chemicals used in your spa are
especially for spa use, and not for swimming pools, as water
quality maintenance of spas and swimming pools is very
different.

Set up a daily program at first to check the disinfectant

level, pH, and total alkalinity of the water to familiarize
yourself with the amount of chemicals to add and to deter-
mine how often to make chemical adjustments during
normal use.  Remember that the more heavily the spa is
used, the more often you must check the water chemistry.

When adding any chemicals, always run the filter system

to ensure complete dilution with the water.  Do not add
chemicals directly into the skimmer opening.

Disinfecting:

When filling the spa for the first time, follow the purge/

sanitizing instructions in the Equipment Set-Up procedure
of the Installation Instructions.

Add a disinfectant to the water on a regular basis to help

control the amount of bacteria, algae and organic materials.
Such bacterial contaminants, if not controlled, could cause
skin rashes or other physical problems.  To disinfect the spa
for normal use, first establish the amount of chlorine or
bromine to add and determine how often you need to add it.

We recommend that you maintain a free chlorine level of

2.0 to 5.0 ppm at all times except when you must exceed that
during the initial purge/sanitizing procedure or during
superchlorination. See “Water Quality Definitions” below.
Superchlorinate your spa every two weeks with heavy use.
If using sodium dichlor, add 15cc (1 tablesoon) for each 565
ltrs. (150 gallons) of spa water.  Scrub the surfaces with this
solution to remove any oily deposits.  This will ensure that
any bacteria or algae which are resistant to the normal
disinfectant level are killed.  After adding the disinfectant,
run the filter system and allow the free chlorine level to
