I'm not sure if I'm doing part of the test correctly. I put in the two scoops (I usually use the .5/10ml fill). Swirl, add the drops and it is usually seems to be pretty accurate. However, I've never once had the sample turn any color when I add the 5 drops of the other drops (not sure what it is called). We really haven't used the pool much yet, but is this normal - to never have any combined chlorine? Here's where I'm not sure if I'm doing something wrong. When I'm done with the test I empty the water in my rocks and add a vial full of pool water to wash it out. When I add this new pool water it turns a little pink - could that be some of the powder still in the vial that didn't fully dissolve or is this a sign of combined chlorine and I'm doing something wrong on the test?
Thanks for your help and opinions.
