I opened the pool about 2 1/2 weeks ago when the water temp was about 50 F. The water was clear, but just a tad cloudy in the deep end so I shocked and ran the pump 24/7 for the first four days. The water cleared and had a successful overnight FC test (no loss). I then adjusted CYA to about 75. Problem is the SWG cannot seem to keep up with demand. Depending on the day we are losing between 1 to 2 ppm. I'm running the SWG 8 hours at 100% of the highest power level (3) and during these losses I am not running the heater or auto pool cleaner. We have had a ton of pollen so I did another overnight FC test last night and did not lose any FC. Last night there was a trace of CC (less than .5 ppm) but that was gone this morning. In testing FC/CC over the last couple weeks there IS at times CC of .5ppm or less but I figured that might be due to solar cover, pollen etc.
Numbers this morning:
Salt: 3500 @ SWG unit 3200 w/AquaCheck Strips.
Any ideas? Do I need to run the pump/SWG an extra couple hours? In the past we've run 8 hours at 50% of power level 2. This is just the third season for the unit and there is no scale build-up etc. I'm stumped
