START UP STEPS
1.
Your swim spa should be filled using a Pre-filter, which can be obtained from your local
dealer. This Pre-filter will help remove many of the minerals existing in the water, which will
make adjusting the water balance easier after a new fill. Never use more then 50% softened
water when filling the swim spa.
2.
During the initial filling of the swim spa, add a sequestering agent to combat suspended
minerals in the water. The agents are sold under many different names such as Mineral Clear
or Metal Protect. Allow water to circulate and filter for at least 30 minutes (or per bottle
recommendations) before adding any other chemicals.
3.
Test water for pH, total Alkalinity, and Calcium hardness. The pH should be 7.4 - 7.6 and the
total Alkalinity 100 - 120 ppm. Calcium hardness levels should be maintained between 150 and
250 ppm (part per million).
4.
Adjust pH and total Alkalinity (TA) utilizing the directions on the chemical bottles. Wait
15 minutes, test and adjust if necessary.
5.
It may be necessary to retest and add additional chemicals to get to the proper levels
in Step 3.
6.
Add concentrated chlorinating granules
*
(sodium Dichlor-s-triazinetreone) to reach a Free
Chlorine level of 5 to 8 ppm on initial start up to begin sanitizing the swim spa water. Bathers
should not enter the swim spa until the chlorine levels drop below 5.0 ppm. Always refer to the
chemical manufacturers dosage recommendations listed on the container. It is important not to
add the chlorinating granules until the pH, alkalinity and calcium hardness have been adjusted
to their proper levels.
*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 spread it 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 Model Specifications section of this
manual for the correct gallons of your swim spa.
The concentration of active ingredients in swim spa chemicals varies by manufacturer. The amounts of sanitizer
suggested in this manual are based on swim spa chemicals that have the active ingredient percentages listed
below:
