Use the included test strips to check the water hardness level and adjust it following below chart.
Lowering Calcium Hardness
If your household water supply is treated with a softener, mix the spa hard water with the soft water
according to the water volume ratio chart to lower the calcium hardness:
Initial level
Desired level:
100 ppm
Raising Calcium Hardness
If the calcium hardness level in the spa water is lower than 100 ppm, add 122 g or 0.269 Lb of calcium
chloride into the spa water.
Muriatic acid is a caustic chemical and liquid solution of sodium bisulfate (NaHSO
is highly acidic. Handle all chemicals with care and wear extra personnel protective
equipment including goggle and gloves. It is very important not to splash acid onto
your skin or clothing, or into your eyes.
