In process of balancing water for pool opening in a few weeks. In testing my CYA, it tested out below 30. I expect it's at or near zero. The water was pretty clear (saw black dot easily) with test water above the 30 mark on the testing tube. I found it strange that my CYA would have droped to 0 from last fall when I was sitting at 40. My CYA is typically pretty stable from fall to spring. We did get a lot of rain, but not unusual weather from years past. The pool surface did freeze this winter (that's a first). Just curious if this drop in CYA sounds strange to the pool experts in this forum. I've already ordered my stablizer... again just curious. Thank You.
