When doing the chlorine drop test where you put that powder in the cylinder of water and it turns pink...do you have to wait a certain amount of time after each drop of R871? I can get it to go clear but if I let it sit there for a few seconds it sometimes will go a little pink again until I add another drop. Does it need to be clear for a certain period of time after adding the last drop to get a good reading?
Thanks,
Scott
