I am a new member, and I have some problems with chlorine levels. I recently bought the TF-100 test kit. This is my first year with a salt generator. I can't seem to get some if any FC. I have shocked the pool over a 7 day period with 20+ pounds of shock. Water was cloudy but now is clear. I have also been running the Salt Generator around the clock for 10 Days.
18x36 vinyl pool 20,000 gallons, cartridge filter, aquabot cleaner. Some help would be gratefully appreciated.
