I am using the TF test kit with two different chlorine test options. There is the simple test and the one that uses the 870 powder to test above 5PPM or more accurately (according to the instructions). I ran my Aqua Rite overnight on super chlorinate because we had gotten some rain and when I tested this morning it was pretty week yellow on the quick test. Maybe between one 1 and 2 ppm. So I tried using the other test to be more accurate. it gave me a reading of 7PPM. which one of these should I trust?
thanks for the help.
