Hi I have a K2006 test kit I just bought and I just read the info below from Pool School. In the test kit directions for testing pH it does not mention adding the chlorine neutralizer before adding the pH test solution. should I be adding this neutralizer? my Fc tends to be around 5-7ppm.
"A measure of how acidic or basic (alkaline) a solution is. A pH of 7 is considered neutral, anything above 7 is basic and anything below is acidic. Pools are usually kept at a pH from 7.2 to 7.8. pH in pools is tested with the indicator phenol red. High sanitizer levels above about 5 ppm can interfere with this test and lead you to believe that your pH is very high when it is actually not! The better test kits will allow for this by adding a chlorine neutralizer to the indicator and calibrating their color comparator blocks to compensate for the added chlorine neutralizer so you can get accurate pH readings when your sanitizer levels are at 10-15 ppm."
