NOTE: It is recommended to measure salt levels once a month.
Below are the instructions for use of the AquaChek Test Strips (Salt Level):
1. Fill a small jar with approximately 1 inch (2.5 cm) of pool or spa water.
2. Insert the lower end of the strip into the water sample. For accurate results keep the top half of the strip completely dry.
3. When the yellow band turns to black, which usually occurs in 3 to 4 minutes, remove the strip from the water sample and determine where the highest white dot (white peak) appears on the numerical scale of the test strip.
4. Compare that value to the chart included in the bottle.
These AquaChek strips measure salt levels from 400 to 7,000 ppm (sodium chloride).
