Guess I don't know what you call a "good test kit". I have city water. I have never had this issue in the 14 summers of having this pool. I always just shock it and put in algeacide.
I used a test strip yesterday and it didn't register any chlorine, which I find hard to believe. I also put a skimmer sock in yesterday and it has lots of brown stuff in it this morning. ??? Does that help?
Uncovered my above ground pool 4 days ago. Have shocked it three times, but it's still green and cloudy. Should I shock it again? Or what? Thanks in advance for any advice.
