My single speed pump is starting to give me trouble so I'm going to take this opportunity to replace it with a VS pump. I'm in Minnesota and currently run 24/7. I was wondering what people think would be a good run cycle for the new VS? We normally don't use the pool a ton during the week but the weekends it's used a lot. I was thinking I would run at 3450 friday-sunday when it's being used a lot and step it down to 1850 or 2100 during the week to save money. thoughts?
