Thread: Specific times of the day where I should run the pump?

  1. Back To Top    #1

    Specific times of the day where I should run the pump?

    I also have a question about my pump. I have a sand filter and a 25,000 gal IG Vnyl pool. The pump usually throws out 80 gal/min.

    With a sand filter do I need to leave the pump on all the time?

    Also, it looks like a 5.5 hour turnaround. If I don't need to run the pump all the time would it be recommended to start at around 10 hours? Are there any specific times of the day where I should run the pump?


    Oh and my first post I love this forum and am super excited I found it.

    Thanks in advance

    I would start at 10-12 hours, and you can try to push it back hour by hour - note any changes in water clarity/balance, until you find your ideal time.

    I personally think it's best to run the pump during the day to prevent FC dead spots. At least 1/2 the total run time during the day. Also when you have swimmers present, have the pump on. Welcome

    Welcome to TFP!

    There is no reason to run the pump all the time, that just wastes electricity.

    I would start with an 8 hour run time and then adjust from there. See How To Determine Pump Run Time in Pool School for more information.
