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.

Good to know and Thank You! It's calling for almost 7 lbs of dry stablizer. This always makes me a bit nervous adding this amount of stablizer. Easier to add than to remove if too much is added. What techniques are used for adding dry stablizer to ensure expected target level? I'm targeting 40 ppm. Hayward chart suggests a 60 to 80 ppm range with 80 ppm begin the target. I have learned to trust TFP for my chem level targets.
