I uncovered my pool to an above average amount of leaves and other winter debris this year. The water was a pollen and dirt cloudy but I didn't see any visual signs of algae. I ran my tests and went into shock mode. During a week of shocking I tested for CC's 3 times and had 0. The water was getting there and I could tell a sparkle was not more than a few days off. Well, yesterday a storm came through and blew all kinds of new pollen, pollen pods, and a few leaves in the pool. We got about an inch of rain. When I tested last night I had 1 CC. This morning I had .5 CC. I have not found anything anywhere other than the pollen pods and leaves that I can attribute this to.
Would someone please explain why I have none when shocking for a week and suddenly have CC's? Could the debris from the rain have done it? The water was about 60 when I started and 68 before the storm. Could the warming water have awakened some organic beast in my pool?
PH was 7.5. Have not checked since I started shocking.
