3. Usage Instructions: Total Alkalinity Test

The Taylor R-0009-C Sulfuric Acid .12N Reagent is used in the titration step of the Total Alkalinity Test. The following steps outline the general procedure for performing this test using a Taylor test kit. Always refer to your specific test kit's instructions for precise details.

Preparation

Rinse the large comparator tube thoroughly with the water to be tested.
Fill the large comparator tube to the 25 mL mark with the water sample.

Testing Procedure

Neutralize Sanitizer Residual: Add 3 drops of Reagent 7 (Thiosulfate) to the water sample. Cap the tube and swirl to mix.
Add Indicator: Add 5 drops of Reagent 8 (Total Alkalinity Indicator) to the sample. Cap the tube and swirl to mix. The sample should turn green.
Titration with R-0009-C: Add Reagent 9 (Sulfuric Acid .12N) drop-wise to the sample. After each drop, cap the tube and swirl to mix. Continue adding drops until the color changes from green to red.

Reading Results

Multiply the number of drops of Reagent 9 used by 10.
Record this result as parts per million (ppm) calcium carbonate, which represents the Total Alkalinity.

4. Troubleshooting

Indicator Bleaching Out (High Chlorine/Bromine)

The most common interference in a Total Alkalinity Test is caused by high levels of chlorine or bromine in the water sample. If excessive sanitizer is present, one of the organic dyes used in the Total Alkalinity Indicator (Reagent 8) may bleach out. When this occurs, the reaction's color changes from blue to yellow instead of the expected green to red.

Solution: To prevent this interference, retest the water sample. In Step 3 of the testing procedure (Neutralize Sanitizer Residual), add one additional drop of Reagent 7 (Thiosulfate), for a total of 3 drops of Thiosulfate. This will help neutralize the higher sanitizer levels and allow for an accurate reading.

Polymeric Biguanide (PHMB) Interference

If a polymeric biguanide (PHMB) product is used in the pool or spa, the water sample may turn from green to purple instead of green to red during the Total Alkalinity Test. This color change, even if purple, can still be used as a reliable endpoint for the test.

Other tests normally performed on pool and spa water should not be affected by the presence of PHMB.
