I drained several inches in preparation for the rain we're supposed to get from the remnants of Barry. Not quite the 6 to 8 inches yet as they were predicting but I tested my cya due to the small water exchange. I tested the water twice with the cya kit and the black dot is disappearing right in between the 30 & 40. I know everyone says cya is only measured in whole 10 increments but should I round up or round down for chlorine level? Also, 30 to 40 makes a much bigger difference than 60 to 70 so should I try to average out the chlorine numbers or just stick to a whole 10?
As a consolation, I guess I get to use my trichlor this whole week with the lower cya than having to poor in bleach in the heavy rain...
