How long to run pump?

[Skillset]

Any other comments regarding total pump run time? I am, too, a brandy-new pool owner. Reading this forum for hours has been awesome - I appreciate everyone's time out there for posting good, honest, information.

From some of these posts, I realized my builder oversized my pump. It's 1.5 HP and figuring feet of head (thanks for all those posts on f-o-h), it does about 55 GPM. My fiberglass pool's only 13000 gallons, so it turn's over in just about 4 hours. We have minimal pool use right now - yard still under construction - so I figure I only need 1 complete turn a day. But, I feel somewhat uneasy about running only 4 hours and letting the water sit still for 20 hours.

Should I ignore the turnover calculation and run the pump a minimum amount of hours per day for circulation purposes?

Water chemistry is fine right now, but I've been running the pump 10 hours a day and want to reduce. Thanks again for all the posts on water chemistry - this is one area I understand very well thanks to everyone on BBB.

Skillset,

Ten hours sounds like a waste of electricity. Four to six hours sounds like your goal.
