I have recently drained my vinyl liner pool to the 50% level and refilled with new water twice in the last 2 days. I started with a CH of way over 1000. I have basically replaced 75-80% of my water. It is now filled and I was hoping to start shocking for the next few days. Here are my results using Tf-100 kit:
cYa below 20 ( would say 0-10)
My questions are:
can I proceed with the CH where it is? I really don't want to spend another $400 on water if I can avoid it.
Should I leave the total Alk where it is or raise it?
