After testing my pool last night with a CC level greater than .5 I decided to shock my pool.
This morning I had an OCLT of 1 ppm and my pool looks crystal clear.
I don't know caused the CC level to go up.
The problem I now have is that I have FC of 30, and my family wants to swim. Is there any way that I can lower the chlorine levels? at what level would it be safe for pple to swim?
