Test was re-run and the aberrant reading was not observed. The earlier reading must have been due to a contaminated vial. ???

I just bought a Taylor K-2006 test kit. I got a shock this morning when I tested my pH. I got a very acidic reading, which did not make any sense because I had checked the pH after refilling the pool and had added nothing but chlorine that could affect the pH reading. I had an older test kit on hand that contained a chlorine neutralizer reagent. I tested with the old test kit using the neutralizer and sure enough, the pH was right on the money, 7.5. I then read the Taylor test kit book. It advises against using the neutralizer and says their reagents contain the chlorine neutralizer and no additional neutralizer is needed. I used a drop of the neutralizer from the other test kit and reran the numbers with the Taylor, and sure enough ... the Taylor kit gave 7.5.
My chlorine level is about 5 ppm (CYA around 50). This is apparently enough to overwhelm the chlorine neutralizer in the Taylor reagent.
Beware! You may wind up trying to balance your pH to a false number!
