    Drain and Refill

    Just drained 60% of my water in order to lower CYA. Now refilling. Shoud I add some bleach during the refill? Thinking about putting a gallon in tonight before I go to bed. I think I drained around 10,000 gallons so I assume mixed with the existing water it should be fine. What else should I do during the refill?

    Run the pump to mix it good. Well, if you can. If you're below the skimmers it'll have to wait.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
