Cap the vials, invert gently to mix (don’t shake), and wait the designated time for color development. Compare results to the color charts in natural daylight, not artificial lighting, for the most accurate readings.
Essential Tool #6: Chlorine Testing Solutions and Comparators
Chlorine testing solutions and comparators serve as the backbone of pool sanitation monitoring, providing accurate readings of your pool’s most critical sanitizing agent.
DPD vs. OTO Testing Methods
DPD testing measures both free and total chlorine levels, giving you comprehensive sanitization data through a distinctive pink color reaction. OTO tests only detect total chlorine and turn yellow when chlorine is present, making them less precise but more affordable. Most pool professionals prefer DPD tests for their ability to distinguish between free chlorine (the active sanitizer) and combined chlorine (less effective chloramines).
Maintaining Proper Chlorine Levels Year-Round
Free chlorine levels should be maintained between 1-3 ppm during swimming season, with 2-4 ppm recommended during extreme heat or heavy pool use. In cooler months, you can reduce to 1-2 ppm while still testing weekly.
