START UP STEPS
1.
Your swim spa should be filled with fresh tap water using a Pre-filter, which can be obtained
from your local Master Spas 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. Always follow the instructions listed on the bottle and 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. There are two different methods you
can use to test your water.
TEST STRIPS:
the swim spa water. To avoid faulty test results, use care when removing a testing strip from
the packaging. Open the package and shake one strip out into your hand, avoiding contact if
possible with the remaining strips. Seal the container immediately so the remaining strips are not
exposed to moisture. Dip the test strip into the water and follow the instructions supplied with
test strips as instructions may vary. Note the colors on your testing strip and compare these to
the key found on the packaging to determine whether elements are neutral, too high or too low.
TESTING KIT:
your swim spa, rather than a strip. Be careful to follow the instructions on your kit, filling the
container to the appropriate level and then dropping the instructed liquid into the container.
Compare the new color of your water to the key provided with the kit to determine how to
proceed. Depending on which kit you purchase, it can test for each one of these elements: total
alkalinity, pH, chlorine, bromine and calcium hardness.
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.
6.
Add concentrated chlorinating granules (sodium Dichlor-s-triazinetreone) on initial start up to
begin sanitizing the swim spa water, according to directions on chemical bottle. Bathers should
not enter the swim spa until the chlorine drops to a safe level, refer to Water Chemistry Guide
in this section. It is important not to add the chlorinating granules until the pH, alkalinity and
calcium hardness have been adjusted to their proper levels.
NOTE:
See the Model Specifications section of this manual for the correct gallons of your swim spa, to
ensure you are adding the correct amount of chemicals. When adding chlorine or non-chlorine
shock/oxidizer always spread it across the water while the pumps are running. The concentration
of active ingredients in swim spa chemicals varies by manufacturer.
