ok after doing 1/3 to 1/2 drain of my pool my cya was about 180 (doing the 50/50 dilute test).
drained another 1/3 today and refilling back up. I will post a full set of numbers when it is full.
Tested before the drain (yesterday evening I added 2 182oz bottles of bleach to bring to 19ppm)
my pool is crystal clear but eating up chlorine like nobody's business. any suggestions, thoughts? fresh numbers coming later today.
