How To Test Your Pool

Pool Water Balance

To complete a full test of your swimming pool you will need to adhere to the Langelier Saturation Index as well as checking for the usual disinfectant and cyanuric Acid levels. This test determins whether the pool is corrosive or scale forming, both of which can cause severe problems for your pool and pool equipment.

The Langelier Saturation Index is formulated from 5 tests:

bullet pointpH (acid / alkali)

bullet pointTotal Alkalinity (carbonates and bicarbonates)

bullet pointCalcium Hardness (calcium content)

bullet pointTemperature

bullet pointTDS (Total Dissolved Solids)

bullet pointTotal Alkalinity= 80 - 120 mg/l

bullet pointCalcium Hardness= 250 mg/l or higher

bullet pointCyanuric Acid= 30 - 100 ppm

bullet pointTDS= 1000 - 3000 mg/l above source water
