Checked my CYA amount yesterday. Due to heavy rains I've drained some this week and test showed I've dropped from 40 to 25. With this week's forcast giving a chance of storms each day (30% to 70 %) should I wait until the weather is more stable to add CYA since it is best not to backwash for a week or so after adding CYA?? Using the amount given on the calculator of course.
