Since it has been a couple of years since the original fill, it may be time to drain half of my water and fill again.

Again, thank you for the information and your input.

The calcium could WELL be increasing your pH--but why has your calcium risen so high? Is it coming from the walls? If so, you need someone to look at it.

I don't know enough about concrete pools to know why leaching would be occuring, except when the water's cal level is low. Is your salt level too high? Salt is notorious for corroding everything, including concrete.

Experts: Is that possible?

Normally, if you can keep your water under control and balanced consistently, you don't ever need to change it.
