We have had 50 degree weather for a week, so I haven't taken the cover off until today. I have spots of green algae growing on the pool flow in spite of maintaining a 5 plus FC LEVEL. Tested every other day and added bleach or cal hypo to keep on the high side of normal. I will begin a slam, but I'm curious as to WHY Algae would grow at a 5 plus FC level.

Pool calculator says to add 2lbs cal hypo to get to recommended shock level. Out of bleach.... Cal hypo is my back up of choice.
