Sand filter/pump question

[mas985]

This Study, courtesy of Ben, suggests that only 3-4 hours per day is necessary for run time. Time of day didn't have much of an effect but a split run time helped some.

I actually did this last summer and averaged about 4 hours per day (2 hour high speed and 2 hours low speed). This turned out to be less than a 1/2 turnover per day and I didn't even notice a difference in water quality. I am not sure that every one can get away with such short run time but it is worth a try.

Well, the shortest run you can saves electricity, though with a 2spd you can run at least 3x longer on low than high for less kwhs.

Thanks for all the help. It is amazing that in 1 week my pool is clear and ready to swim, eventhough the air is not quite warm enough yet. I will let my FC come down to about 5 and run the pump once a day for 6-8 hrs instead of 24hrs non stop.
