Water Quality
Note:
Perform water quality testing weekly and whenever your water is changed (or
when your spa / hot tub is first filled).
Once your spa / hot tub reaches 95ºF / 35ºC, properly adjust the chemistry of your
spa / hot tub water by testing it with good quality test kits and adjusting levels as need-
ed.

Total Alkalinity
Important:
Total Alkalinity (TA) is the first parameter you should balance when
making routine adjustments to your water.
Once your water temperature reaches 95ºF / 35ºC, test the total alkalinity of your spa /
hot tub water with a good quality test kit. Maintain a total alkalinity level of
80 to 120
ppm
.
Total alkalinity is the measure of alkaline buffers in your water. These buffers protect
the water against sudden changes in pH. Total alkalinity is considered the key to water
balance.
When the total alkalinity is too low, add sodium bicarbonate. If the total alkalinity is too
Acid Alkaline Balance (pH)
Test the pH of your spa water with a good quality test kit. Maintain a pH level of
7.2 to
7.8
.
A balanced pH promotes bathing comfort and prevents corrosion, staining, scaling, or
cloudy water.
If the measured pH is too low, add soda ash to the spa water. If the pH is too high, add
sodium bisulfate to the spa water. Follow the directions on the manufacturer’s label
and make small changes. Circulate the water for 20 minutes before retesting.
