    Must I shock?

    I've had my pool open since April 1st, here in Atlanta. My numbers have been consistent.

    I'm getting ready to close for winter..(30-45) days...disconnected SWG in I have been following CYA/Chlorine levels for non-SWG pool...the pool has been great. My questions...
    Pool Calculator says to bring my pool to 28 to Shock the pool...wait 24 hours and check. Then wait another day and a half..wait to FC is about half...then add Polyquat 60 and Mix for 1/2-1 hour.
    My pool has been CRYSTAL Clear all summer. Can I skip the Shock step..Just bring my FC from 7 to 14 add the polyquat and procede to follow the closing procedures you annotated on the sticky..or am I being foolish?

    Go ahead and shock. May not be 100% necessary but you could easily regret it you have organics once you close.

    Have you thought about keeping it open? Myself and a few others in our area have done it for a few years now and it sure makes spring swimming much easier. We'll swim in ours until mid October so it's not too much down time.
