    Filter Run Time

    I have a variable speed Pentair pump. If I'm understanding the literature correctly, the default setting is to run for 8 hours at high speed, and then run two 4 hour cycles at progressively lower speeds.

    However, my PB to me to set my timer on the breaker for 12 hours a day. Is this enough time for the pump to run?

    The reason I'm asking is because I had a cloud in my pool that I thought might be mustard algae, but after running the pump on override for 24 hours on high, the cloud was gone. I have been running the pump on the 12 hour cycle since then (about 7 days) and the water has remained crystal clear.

    I'm wondering if the cloud was an anomaly, or if I should expect this type of particle build up every so often on the 12 hour cycle. I want to run the pump as much as needed, but only as much as needed!

    Thoughts?

    Re: Filter Run Time

    Im not an expert but my reading suggests that 12 hours is longer than needed if the chlorine is right

    I run mine for 4-5 hours and its always clear...

    Edit to add - mine is a VS pump running at ~2000 rpm so its not at full speed either

    I have a single speed pump that I run for about 6 hours each day. 2 separate 3 hour sessions. One about mid-day and one in the evening. Mostly based around trying to maximize daytime heating and when I normally test. It's plenty for circulation, provided I run my robot about twice per week. I would guess you need to run longer so that your Polaris can run. Does it clean well on low speed or do you have a separate booster pump?

    I have a booster for the Polaris, and it does clean well. I think the problem may be that my patio is about 2,000 square feet, and we use a leaf blower to clean it....more dust than I think must be getting in the pool. I will change to an 8 hour cycle and see what happens. I doubt I need to run mine 12 hours if y'all are running yours 6 hours. I think I can lightly spray the deck with water before blowing it off, which should keep so much dust from flying into the pool. Thanks to all!
