Water Clarity
This section is intended for new spa owners with
no experience with water chemistry. Everyone’s
experience with maintaining water quality is
different, but there are some general concepts you
need to know.
Water maintenance is not difcult, although it
requires 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
Water
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
enjoyment of your spa and extends your spa’s
life by preventing damage from neglect and
chemical abuse.
See page 30 for the schedule of recommended
maintenance.
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 bromine as
your sanitizer.
Spa owners with an ozonator also need to
add sanitizer, although their requirements are
different.
See page 25 for learn how to
use sanitizer.
The Cal Clarity II bromine
generator does NOT require
sanitizer. See page 28 for a
description of its use.
Filtration
Cleaning your lter regularly is
the easiest and most effective
single thing you can do to
keep your water clear.
A clogged or dirty lter 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 ow through the
system.
See page 27 for lter cleaning instructions.
Chemical Balance
You will need to test and adjust the chemical
balance of your spa water. Although this is not
difcult, it needs to be done regularly.
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
II bromine generator also need to check total
dissolved solids and phosphates.
See page 24 for learn how to
balance your spa water.
The Key to Clear Water
Excellent water quality is a simple matter of four things:
A Note on the Cal Clarity II System
The information in this section applies to all spas.
However, the Cal Clarity II bromine generator has
a few specic requirements and exclusions, which
are called out where they occur in this section.
The Cal Clarity II system uses its own bromine
chemical additive and does not require a sanitizer.
Spa owners with the Cal Clarity II system need to
learn how to use the system to prevent voiding
their warranty.
