Clear Water Plan
This section is intended for new spa owners with
no experience with water chemistry. Everyone’s ex-
perience with maintaining water quality is different,
but there are some general concepts you need to
know.
Water maintenance is not difficult, although it re
-
quires regular attention. The most important thing
to understand about taking care of your spa water is
that preventive action is much easier than correcting
water quality issues.

Your Key
To Clear
Wa

Regularity
Clear water requires regular maintenance.
Establish a routine based on a regular
schedule for your spa water maintenance.
Maintaining your water quality helps the en-
joyment of your spa and extends your spa’s
life by preventing damage from neglect and
chemical abuse.
See page 29 for the sched-
ule of recommended main-
tenance.
Sanitation
Sanitizers kill bacteria and
viruses and keep the water
clean. A low sanitizer level
will allow microbes to grow
quickly in the spa water.
We recommend using either chlorine or bro-
mine as your sanitizer.
Spa owners with a Cal Zone 2000 ozonator
or a Cal Clarity bromine generator also need
to add sanitizer, although their requirements
are different.
See page 25 for learn how to use sanitizer.
Filtration
Cleaning your filter regularly is the easiest
and most effective single thing you can do
to keep your water clear.
A clogged or dirty filter will cause the heater
and pump to work harder than they need
to, possibly causing them to fail.
The spa’s heating system will only function
with the proper amount
of water flow through the
system.
See page 27
for filter clean
-
ing instructions.
Chemical Balance
You will need to test and
adjust the chemical bal-
ance of your spa water. Al-
though this is not difficult,
it needs to be done regu-
larly.
Depending on your choice of sanitizer, you
need to test the level of calcium hardness,
total alkalinity, and pH. Spa owners with
a Cal Clarity bromine generator also need
to check total dissolved solids and phos-
phates.
See page 25 for learn how to balance your
spa water.
