I'm just curious if anybody on the forum has a similar situation to me, i'm wondering what your FC levels are and how quickly they drop.
I have an above ground 3,000 gallon vinyl pool with cover.
Southern CA, water temp is around 55-60°
Run the sand filter 4 hours a day.
Seems I'm only losing about 1ppm of FC every week, which is awesome.
Is this pretty standard under these conditions?
I knew the FC would last longer in winter, but didn't expect it to last THIS long!
