To properly titrate (apply drops) while testing, reagent bottles need to be fully vertical during titration to ensure that the correct drop is produced. Fill test cell to line with hot tub water, add 5 drops of Phenol Red solution to pH test cell and 5 drops of OTO solution to CL test cell. Place cover over both test cell openings and invert several times to mix. Compare each test cell to its respective color standards.Â
