    Draining and refilling Pool

    I understand that I need to test the water before adding chemicals to it.
    I would like to know if anyone has a good estimate of what I will need to balance out my 40k gallon pool so I can go shopping ahead of time.

    If you'll take your test kit and run a full set of tests on your fill water you'll have a pretty good idea of what you may need once you fill it.
    Chlorine of course, but the rest depends on the fill water.

    Certainly will need chlorine and stabilizer (CYA). But any adjustments to the pH, TA, or CH depend on your fill water as Dave stated.
