I read that the fc level should be between 3 - 5 for a swg, is there a problem with it being a little higher than that? Here are my tf-100 test results:
The water looks perfect at this level, when the fc was around 4 it would get a slight cloudiness with heavier use, but at 7 / 8 where its been for the past month it stays crystal. I know this may be causing more wear to the swg so I will prob adjust down to 45% run time from 50% on the cell to lower it a little, pump run time is 12 hrs.
I keep adding cya, but due to my auto cover when there is a lot of people, water splashes into the vault so the cya level keeps dropping, I added 8 pounds in the last few months. I guess if I really raised the cya to 70 - 80 the fc level of 3 - 5 would keep the water clear?
