For the last 7 days CC has been .0 then yesterday .5 on the .5x and the .2x, then today .0 again. I don't know what is causing this, happens about every 10-15 days. Add enough bleach to bring up to 8 every night, losing only .5-1.0 a day rain or shine - ph/ak stable once a week adjustment of .50. Outside temp 50-60 Pool Temp 50-52. Any thoughts?
