00:00 - Intro01:11 - Things can go wrong in water testing, so let's review the common mistakes and interferences.05:07 - Reagent expiration dates mean nothing if the kit is not stored properly. All test kits have a finite shelf life.09:10 - Bleaching reagents (very high chlorine) can distort other tests too.15:08 - Cold water interferes with accuracy too. Warm the sample before testing.18:48 - Mistakes are common when collecting a sample and taking it somewhere. Grab the sample from below the water surface, fill the clean bottle completely without a big pocket of air in it, and then take it directly to the pool store or lab. The longer you wait, the less accurate the test results.23:29 - A few other items: lighting is important for color comparison tests, and if you notice something is way off, test again and examine your test kit for problems. Practice, practice, practice.26:49 - Summary.
