I just got my k-2006 test and these are the results I got. My pool is cloudy, I can see the bottom of the shallow end but not in the deep. We just moved into this house two weeks ago and the pool was green when I started. I didn't know better and went to the pool store recommended by the previous owners. So far everything the store has had me try has not worked so I decided to do some searching online myself and ended up here.
CYA 30 I am not really sure about this, I could still see the black dot at the bottom of the tub but it was full so I am guessing this is the lowest reading the test allows
