My pool guy set my up opposite of that when he installed my new pump. I Put in a pentaire variable.. run it 24/7
I think it is set at 2400 for day and 1200 for night.. summer and winter.. the pool stays spotless and has really stabilized efforts to keep it all in line..you can not hear it at all at the lower speed even when right next to pumps.
well the power consumption is minimal because of the variable speed. Running it fast still pulls amperage.

I run it all night off at 8am and back on at 3pm unless we are using it.

I want the water moving at night to have more heat exchange to cook as much as possible. Running all day warms it

We’re surprised you run yours so little


Mine only runs for 3 hours. 20-25k gallon, chlorine, full sunlight. I follow Trouble Free Pool too. Haven't had to 'shock' it once in 7 years. Have come close a time or 2 but only when out of town or unable to take care of it (recovering from a broken collar bone at the moment). Test your CYA and chlorinate accordingly. Not much else to do except add acid, have a spa overflow that raises pH.

Wouldn't want to see an electricity bill from running it as long as most of y'all are.

I run mine 8am to 8pm and run Polaris as needed. Pool stays clean. I fill the chlorinator once a week. I run the water fountain feature all nigh when I want to cool the pool 4-6 degrees-it works and really makes a difference.

I'm a firm believer in the TFP method, but only running the pump 3 hours and having perfectly clear water is very hard to believe. Unless there's some extremely super pump that turns all that pool water over in that short amount of time, that is.

Yea, unless he swims in his pool for 8 hours wearing cartridge filter swimwear.

Or has an indoor pool.

well just guessing on his info, 25k pool is off of my pump chart but 20k is not.

my pool is around 18.5k. my pump will turn my pool over in 3 hours with 40' of TDH. do i only have 40' of TDS probebly not.

But i run my pump on high for 3-4 hours and then on low for filtering for 4-6 hours.

You know need to turn your pool over once every 24 hours. Most people run their pumps too much, but as discussed earlier in the thread, there are reasons i dont argue with because i have mind turn on when we are outside for the ambiance.

Ok, ya got me. Don't remember exactly when this changed as I never mess with it but it's on for 4 hours, not 3. Everyday 6am to 10am. Trying to avoid evaporation. Don't want it running overnight as it attracts frogs and stuff.

As long as it’s skimming the surface and keeping it clear of debris, good for you. Keeping your water chemistry right will prevent the algae.

My pump runs from 7am-11pm. I had it running 24/7 for the first 4 months.

Seems like starting and stopping 3 times a day would put more strain on the pump.

i dont think id worry about that. think of all the motors you turn on and off all day.

This thread is making me want to play with reducing run times. I run on medium during the day, then very low speed at night. It’s 24x7 though, so the heat pump can turn on whenever it needs to. (Obviously not a concern right now.)

you only need to run you pool on high for long enough a day to keep your pool skimmed. low will filter the pool water and get the turnover needed. and is way cheaper to run than high. here is a chart from the Department of Energy.



see the star. a reduction from 3,450 to 3,000 rpms cuts your wattage down almost half.

High speed is 6x what the lowest speed (66gpm vs 11gpm) but after 6 mins moving the same amount of water the lowest speed used 54 watts vs 2000 watts of the high speed.

I know, but I've been too lazy to figure out how long that is. I reduced it from 12 to 8 for now and will monitor. I don't have any trees around, so I bet I can get away with quite a bit less.

A+ thread

i would bet an hour or 2 would be plenty if you have very little leaves.

I did notice last night that if you dont have it running for an extended about if time you will see like "dust" and spider weby things. But im testing how my pool heats up during the day and weather keeping the pool stagnated during the day and during the cool off period, keeps the over all temp lower. or if it doesnt matter.

I switched to only nighttime running about a week ago. Started at 12 hour duration for the first few days as I was dealing with the last bit of algae and crepe myrtle flowers. As of today, the Pool has cooled off 5° and FC is more stable than it has ever been during these hot days. I reduced the run time to 9 hours tonight and will test chlorine loss tomorrow evening. I follow Trouble Free Pools chemical regimen and have a salt water pool.

Mine run 12 hours a day. We have water features so it runs 8am-8pm.
