OK, this is strange. Last fall, in November, my CYA was at 40 ish
The only chems added through the winter is bleach to keep FC at around 3 ppm
I did not check again til a week ago. I had assumed it would be very much lower than 40 because throughout the winter I have replaced 16 to 20 inches of water due to lots of rain and some snow. About a week before checking (a week or so ago) I had added about 3 lbs of dry CYA using the sock meathod. Had also put some cellulose fiber in the the skimmers as a filter aid. To my surprise, the CYA level is at 80. I thought nothing but Conditioner would raise CYA and certainly 3 measly lbs in a 26,000 gallon pool would not raise it this much. Any idea how this could happen?
The Bleach I have been buying is some new stuff that is concentrated so it says it is "equivalent to 181 oz of the normal jugs. It seems it is all that is available in my area.
