    reading FC test

    I did the test as instructed and got a .5 FC level. But, I looked at it a minute later and it was back to pink. Do I add drops till it stays clear or till it turns clear the first time?

    it should stay clear for a good 30-60 seconds. if you let it sit longer than that it will turn pink again.
