Water Balancing - Premium Leisure Swimmer’s Edge 18 Owner's Manual

W a t e r B a l a n c i n g
Note: Perform water balancing weekly and whenever you change water
(or when the swim spa is first filled) to ensure proper water condition.
Once your swim spa reaches 95ºF, use our Bromine Test Strips (not included)
and add the necessary chemicals (not included) to stabilize your water chemistry.
Turn Pump 1 on high speed before starting your tests to distribute chemicals
evenly. Wait 5 minutes between measurements to allow added chemicals to mix
thoroughly.
Important: Test the condition of your water in the following order:
1. Total Alkalinity (80-120 ppm) – Use our Alkalinity Increaser to raise total
alkalinity and Alkalinity Decreaser to lower it. Low total alkalinity has little
buffering capacity making the pH erratic. High total alkalinity has too much
buffering capacity making the pH difficult to change.
2. pH (7.2-7.8) – Use Spa Up to raise the pH level and Spa Down to lower it.
Caution: A pH lower than 7.2 can harm the metal surfaces of your swim
spa and irritate your eyes and skin. A pH higher than 7.8 can
create calcium deposits (scaling) on the shell and equipment.
3. Hardness (150-400 ppm) – Add Increase Calcium until the proper level is
achieved. Unfortunately, there is no practical way to lower the native water
hardness other than using a different source of water when filling your swim
spa. Low hardness causes equipment corrosion and water foaming.
4. Sanitizer (3.0-5.0 ppm) – Use our Deluxe Bromine Kit to add Bromine until
the proper level is achieved. Neglected swim spa water can breed bacteria
and algae causing bather discomfort, skin rashes, and/or irritation.
