Hi. New to this testing method. I need help making sure I understand the two test options for chlorine measurement. 1. The small gauge that has one side chlorine and the other ph- I measure the chlorine as instructed with adding drops and the yellow always appears darker than the highest reading. So I move to the larger chlorine 10ml and powder test. I add the drops and count them and then multiply 0.5 and it comes out as like 3 or 4. But shouldn’t this show up on the other test as within that window since it’s not actually showing higher than the scale reads?
