    How long to run pump for?

    I've read most of the topics, and the more I read the more confused I get!

    I have approximately a 14,000+ pool. I also have a 1.5hp pump ao smith centurion switchless motor (dont know what any of this means) i can't seem to find how much water it moves.

    I read you are supposed to turn over your water once a day, others say a few hours, others say 1 hour per 10 degrees, others say split the time! Im so confused :/

    Anyhow i was wondering i am in texas, 95-105 degrees. Should I run pump early, late or split it? Obviously I would add chemicals at night and run it 1-2 hrs? Then run it 6-8 during the daytime? Any help is greatly appreciated! I believe i have 2 1/2 inch piping by eye balling! Thanks!

    IN most cases here you will find that pool "turnover" is irrelevant. What you hear at pool stores simply doesn't have significant bearing on the condition of the water aside from simply skimming the surface for debris. You run your pump long enough to simply adequately mix chemicals throughout the water and then to achieve a reasonable amount of surface debris remove to the skimmer(s). Of course you crank-up the pump higher for other operations like vacuuming, SWG, solar, etc. All of these things vary from pool-to-pool. so experimenting with your pool is key.

    Hope that helps.

    A couple of hours would probably get all the chems mixed and there for the water would be sanitary but there is also the filtering of dirt and debris to be considered. I would start with 3 or 4 hours and see how the water looks. If it gets a bit hazy or leaves and debris start being noticeable increase by 30 min to an hour every couple of days till you like the look. Multiple run times can help with skimming because it gets the debris into the skimmer before it has a chance to sink. If you don't have a lot of trees to deal wiht it will not do much for the overall look of the water.

    I do have a few trees and leaves do become some what of a problem if its windy, if not i get a few a day! Would it be ok to do say 2.5 hours in the morning and 2.5 hours in the evening? Or 2 and 2? I guess my q is as long as the total run tume equals whatever keeps it clean im fine? Say my magic # is 5 hours does it need to be continuous?

    One suggestion, you may want to consider adding chemicals in the AM, since much of your FC loss will be mid-day in the TX heat. If you can give your pool a little boost in the morning, you'll may find that you have fewer issues related to low FC.

    Awesome! Even better. My concern was since my kids like to swim anywhere from 10-7 as long as i add chemicals at 8 and its just keeping up no insane amount they should be good to swim an hr or two later correct?

    For instance yesterday o added 50ozof 6% bleach, through readig it said that basically you can swim almost instantly as long as you spread it?

    Run time does not need to be continuous so yes you can split 2, 3 even 4 times however you like. Kids can jump in fairly soon after chemical adds, an hour is a good rule of thumb, I admit I have jumped in after 15min and did notice a slight chlorine smell so probably a bit too soon.

    Mine is split as well. 2 hrs in the am and 2 hrs in the evening. I add chemicals in the evening just more convenient that way.
