    Thanks Ben.

    That's good news! So it ended taking 16 jugs of bleach total (about $50). Not too bad....I had fears it would be much worse!

    Btw, this whole time since removing the cover Saturday, the water has been clear, and after vacuuming yesterday morning the pool looks great.

    Just checked FC...dropped to 16 (from 25.5 early this morning). Today was sunny all day. Hopefully it will hold overnight. If not, should I bump it back up to 20?

    Nah. Unless you have algae or slime, let it drop to levels appropriate for your current CYA level

    Thanks. No algae or slime, so I'll let it drop to normal. 5-6 seems to be the sweet spot for my pool given CYA 60-80 recommended by my SWCG manufacturer (Goldline Aqua Rite, now Hayward).
