Found this site early last year, read and studied, got Ben's testkit and did BBB.
Loved it! 2 ppm loss per day without solar cover with a cya of 40 the whole summer.
This year it is 3-4 ppm, 2ppm with the cover!
I am starting to raise the cya and now it is at 50-60 but no improvement.
What could the reason be for the difference? Water is clear,no CC

Thanks

Dan
