of the container, with about 1 inch of the
strip below the surface of the water.
ii. Stir the water continuously, while you slowly
add water treatment compound until a color
between indicating a pH of 10.5 and 11.5 is
reached. (Shown on the pH test kit chart.)
Judge the pH by frequently comparing the test
strip with the color chart provided in the kit.
