How do you calculate head?

Well, if it helps any, I was running my pump for a 1/2 turnover during the winter and now I am runing it a 1 1/2 turnovers per day and the water is crystal clear. However, my bather load is light.

One thing you might want to try, is to lower the run time gradually. Drop a few hours each day until you hit 12 hours so you can monitor any changes.

I may do that. I think there's an intermatic timer at my in-laws that they use for Christmas lights, I'll see if I can borrow it and do some playing around.

We're coming into the hottest weather, so it should be a good test
