Backwashing and shocking

[Watermom]

Yep. You done good! Tonight, test the cl at sundown and then early tomorrow morning and see if you lose more than 1ppm. If you do, shock it back up. Continue keeping high cl until you can hold it overnight. Also, retest your pH whenever your cl isn't high so you can get an accurate reading.
