Yes guys, I have another question....LOL! My pump is a 1.5 HP 70 GPM Hayward. How long do you think I need to run it per day! I am thinking about trying to add bleach in the evening...let it circulate a couple of hours and then shut it down until morning. Any suggestions? My water is balanced but remember I am maintaining a CYA of 80. Don't know if that makes a difference or not.
