How should I test for chlorine and pH? 

A recommended and easy way to test for pH and Free Available Chlorine (FAC) is to use 3-Way Test Strips. The color pads on these strips are quick indicators for pH, FAC, and Total Alkalinity (TA).

Note: 3-Way Test Strips are the most convenient way to test your pool water, but they are sensitive to moisture. Keep the bottle tightly capped.

Another effective method involves the use of a DPD test kit; a more traditional method using vials and reagent drops to measure pool water balance factors.

Either kit may be obtained at your local Sustain dealer.

Heaters, pumps and metal fixtures are attacked by aggressive, acidic, (you guessed it) low pH water.
