My pool is 14,600 gallons and the pump has been running 24 hours for 6 days straight w/o a backwashing.

According to this site: http://www.csgnetwork.com/poolchemcalc.html

I can add 6# of CYA to get the level to 50ppm

I'm just curious how long after the sock is empty do i have to wait for the reading to be accurate...

thx
