    cloudy days

    do I lose as much chlorine to the sun on cloudy days, as I do with full sun?

    My guess, and it's a guess, is almost. Clouds do not block much UV rays which I believe are the primary reason for Cl loss. That said, they do block some so my assumption is you would use less but not much less...maybe 25%.

    I usually don't respond with guessing but no one answered your post yet so this will bump it back up for someone who is more confidant with their reply.
