DO NOT DIVE.
Step 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.
Step 2:
During the initial filling of the swim spa, add a sequestering agent to combat sus-
pended minerals in the water. The agents are sold under many different names such as
Mineral Clear, Stain and Scale, Metal Protect, and other brands. Allow water to circu-
late and filter for at least 12 hours before adding any other chemicals.
Step 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).
Step 4:
Adjust pH and total Alkalinity (TA) utilizing the directions on the chemical bottles.
Wait 15 minutes, test and adjust if necessary.
Step 5:
It may be necessary to retest and add additional chemicals to get to the proper levels
in Step 3.
Step 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 manufactures dosage recommendations listed on
the container. It is important not to add the chlorinating granules until the pH, alkalin-
ity 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 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:
