    Good idea. One suggestion is to keep them in alphabetical order since it makes it easier to find what you are looking for!

    What is PF in members' signatures?
    Just moved in so I'm not exactly sure on manufacturers or specs; best guess: 24' x 48" AGP, sand filter with 3/4HP pump, Taylor K-2006

    PF = pool factor.

    If you add 1 lb of chlorine gas to a pool with a PF of 1 (120,000 gallons = 1,000,000 lbs) you get 1 ppm of chlorine.

    If you add 1 lb of chlorine gas (100% chlorine) to a pool with a PF of 10, you get 10 ppm of chlorine.

    If you add 1 lb of dichlor (55% chlorine) to a pool with a PF of 10, you get a 5.5 ppm of chlorine (1 x 10 x 0.55)
