    Algae?

    I just did another overnight FC loss test and went from 14 to 11 with a CC of .5
    It rained a bunch yesterday and there are a lot of leaves and sticks in the pool I need to get out today. I spent the last 2 weeks shocking the pool and 2 days ago showed an overnight loss of only 1. Could the leaves and all the rain cause last nights loss...or do I still have algae? Water looks clear - I can see all the way down to the main drain, I don't know if I would call it "sparkly" though.
    I'm scared the green monster will creep back!

    When you get a lot of debris in the pool it will consume chlorine, so the overnight FC loss test doesn't really tell you anything today.
