SPA WATER CHEMISTRY AND BALANCE (continued)
WARNING
Muriatic acid is a caustic chemical and liquid solution of sodium bisulfate (NaHSO
4
)
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.
Lowering pH Using Sodium Bisulfate
Calcium Hardness Adjustment
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 1000 ppm 500 ppm 350 ppm 250 ppm
Desired level:
100 ppm
Water Volume Ratio (Vhard water:Vsoft water)
1:9 1:4 2:5 2:3

Raising Calcium Hardness
If the calcium hardness level in the spa water is lower than 100 ppm, add calcium chloride into the spa
water.
