Hello, can you help me figure out what's going on with my FC readings? Tested my water this past Saturday and got these readings:
The weekend before my FC was at 8 and before that it was at 4.5. I've never had a reading so high for FC. After Saturday's test, I turned off the chlorinator on the system so the salt cell supposedly hasn't generated any since 4 days ago, but I just tested it again and get the same reading. The weather here has cooled off in the last 2 weeks, is that it? My pool temp at the moment is about 65 degrees. Please help, is something abnormal going on? Thanks.
