I remember that there was a thread debating this (before I got my pool) but I cannot find it. Since I am closing the pool today I wanted to be sure to get a good reading. In direct sunlight it is below 40, in indirect sunlight it is 50. So my question, which do I go with - I am leaning toward the 50 and will chlorinate as needed using that number, unless you all tell me otherwise.

Thank You!
