I would like to take advantage of my variable speed pump and the built in timer. As I have mentioned in earlier posts my PB has pretty much abandoned us with our project so I need a little help. I downloaded the manual for the pump and now reach out to the experts as to the settings. It is a 4 speed pump. It has been running 24/7 on speed 3 for 6 weeks. Water chemistry is great. What would be the optimal setting for this? Do I just run it for a while during the day and leave it off at night or run speed 1 overnight and speed 2 or 3 during the day?
