Hi all,

I am a new to the forum so thank you in advance for letting me post to the community.

I was gone for a week and my chlorine got out of balance. I was using the local pool stores for water testing which after finally purchasing a commercial Taylor kit 2006 found out that their tests were way off. Here is the situation as of this morning.

FC 7 ppm
CC 20ppm
alkalinity 120
PH 7.0
CYA 60

The problem is that I cannot maintain FC throughout the day, but CC seems to keep going up every time I shock the pool. Last evening no FC, but CC of 22. Added 6 lbs of shock last night and this morning I have the results posted above. I have read that I need to keep shocking the pool until CC is gone. How is it best to do this and how much shock do I need? I have not tried to increase PH at this point until I get the chlorine issue under control.

Thanks,

Robert
