WATER MAINTENANCE – SCHEDULE
AS NEEDED
If water looks hazy, check PH and Total Alkilinity, and treat with chlorine*. Always refer to the
chemical manufactures dosage recommendations listed on the container. Free chlorine levels
should be maintained between 2.0 - 4.0 ppm.
These are general recommendations for water maintenance that may vary by usage and bather
load. Depending on bather load and frequency of use, drain and refill times may vary as well as the
frequency of cleaning your filters.
A defoamer may be used when excessive foaming occurs. Over use of a defoamer will result
in cloudy, milky water.
USE ONLY SPA CHEMICALS
Do not use chemicals designed for use in swimming pools.
With a swim spa you are working with a small volume of hot water compared to a large volume
of relatively cool water in a swimming pool. Because of this chemicals will have a shorted life span
and bacteria can grow more quickly than in a swimming pool. A swim spa is less forgiving then a
pool and requires that whatever is put into it have a pH as close to neutral as possible. That is why
only chemicals made for spas should be used. Always refer to the chemical manufactures dosage
recommendations listed on the container.
*SPECIAL NOTE:
We recommend a minimum level of 2.0 ppm residual free chlorine be maintained in swim spa water. Always
refer to the chemical manufacturer's dosage recommendations listed on the container.
When adding chlorine or non-chlorine shock/oxidizer always broadcast across the water while the pumps are
running.
The quantities of sanitizer and oxidizer shown in this manual are for 500 gallons and may have to be adjusted
depending on the actual amount of water that your swim spa holds. See the specifications section of this manual
for the correct gallons of your swim spa.
The concentration of active ingredients in spa chemicals varies by manufacturer. The amounts of sanitizer sug-
gested in this manual are based on spa chemicals that have the active ingredient percentages listed below:
Chlorine
Active ingredient:
Sodium dichlor ................................. 99%
Other ingredients ................................ 1%
Total ............................................... 100%
