SPA WATER CHEMISTRY AND BALANCE (continued)

Calcium Hardness (CaCO

refers to the amount of calcium and magnesium dissolved in the water.

Result if too low – Diﬃ culty balancing water, corrosion of metal components, eye & skin irritation and water

foaming.

Result if too high – Scale formation, cloudy water, eye & skin irritation, diﬃ culty balancing water and ﬁ lter/

heater ineﬃ ciency.

Saturation Index (SI):

temperature, calcium hardness concentration, total alkalinity and pH represent the

main factors inﬂ uencing scale formation. The tendency of water to either form scale or corrode is indicated by

the Saturation Index (SI):

SI = pH+TF+CF+AF-12.1

*Where: TF = Temperature Factor; CF = Calcium Hardness Factor; AF = Total Alkalinity Factor

Test the water pH, Temperature, Calcium Hardness and Total Alkalinity levels. Use the equivalent Factors in

the SI equation.

SI = 0, Balance

If SI > 0, Scaling or cloudy water condition.

If SI < 0, Corrosive to metals or eye & skin irritating condition.

The SI is considered satisfactory if the value is within -0.3 to +0.3 range. Zero being perfect.

WARNING

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.

SPA Water Adjustment

How to adjust the spa water chemistry when the levels are oﬀ the range.

CAUTION:

Always follow the chemical manufacturer’s directions, and the health and hazard warnings.

Total Alkalinity (TA) Adjustment

Remove the spa cover to aerate the water and use the included test strips to check the chemistry level.

Ensure the chlorine level in the water is between 2-4 ppm ﬁ rst, as chlorine will aﬀ ect the TA test result.

If the TA level (and not the pH) is higher than 120 ppm, add appropriate chemical product to lower the TA

level.

If the TA level is lower than 60 ppm, add appropriate chemical product to raise the TA level.

NOTE:

After adjustment, retest the water after 24 hours and adjust again if necessary.

pH Adjustment

After the total alkalinity has been lowered to 120 ppm or raised to 80 ppm and the pH is still high or low, add

appropriate chemical product to adjust the pH level between 6.8 and 7.6.

Calcium Hardness Adjustment

Use the included test strips to check the water hardness level and adjust it with appropriate chemical product.
