On 24/7? OUCH.

Figure one turn per day. Calculate volume and find what your pump turns in gpm relative to horsepower and divide the amount into the total pool volume.

Or, just go with about 6-8 hours in the summer.

I run mine for 6 hours during the summer, from 5 pm to 11 pm. I, too, have a SWG, and with these run times I'm able to maintain 4-5 ppm FC.

One of the dangers of running your pump for so long, especially with a SWG, is your chlorine levels might get too high since your system is generating chlorine 24x7. For me, running my pump 6 hours per day, and with my CYA level at 60-ish, I'm able to keeps up with the chlorine burned off by the sun during the day and maintain the 4-5 ppm I mentioned earlier.

Several weeks ago when we had three straight weeks of rainy weather here in the Dallas area, I got caught by surprise when my chlorine level was as high as 12ppm. I concluded that since my SWG was continuously generating chlorine, albeit for only 6 hours each day, I was actually generating more chlorine than I needed each each day.

For standard 18x31 pool you are looking at about 6hrs in summer and 4 in winter. I have salt and I actually do 3 in winter just fine, 6 in summer. You usually run 24/7 during intitial start up but that is it.

I run mine 4 hrs a day but we have an auto cover with a SWG. Our water chemistry is almost always spot on.

wow. i don't get it. we were told to run it at least 18 hrs. a day. the pool guy who came at the end to go over everything with us said he leaves his running from mother's day to labor day. does anyone run their filter at all close to these numbers?

It all depends on a variety of factors, as joelq has indicated...size of pool (amount of water to turn over), capacity of equipment (determines how fast your water turns over), amount of sun on the pool (more sun means your chlorine doesn't last as long), CYA level (determines how well your chlorine "holds"), SWCG setting, and pump run time.

Then, there are all the other variables like when you run your pump, efficiency of your filter, cleanliness of your filter, bather load, whether or not you use a cover, and how much other debris gets into the pool.

So, it's very hard to compare pools in different settings with different challenges in different parts of the country.

How does your pool look? How are your testing numbers? If it's all good, then you could try backing off of the pump run time (and/or reduce your SWCG setting) a bit and see how it goes...but be sure to keep testing your water. Keep good notes of your changes and, over time, you'll see where you can keep your pool happy and reduce your energy bills as well.

I'm in just my 2nd year with this pool and I'm still learning and tweaking. Currently, I'm at 10 total hours split into 3 different intervals. As the air temps are going up over 100, if my chlorine doesn't hold, I can either increase the pump time, increase my SWCG setting, increase my CYA level, or simply supplement chlorine for awhile with bleach. But the key is to keep testing so I know what the pool needs.

App 15x28 lagoon shape (3x5 Deep) plus 7' spa screened in. SWG Cartridge Filter. Florida Summer. 8hrs/day maintains chlorine between 2-4 normal range.

Filter is on 6 hrs in the middle of the day during summer (May to Oct) with the solar on. But regradless of schedule, it is always on when when swimming plus about 2 more hrs after.

On for 6 hours during winter (Nov to Apr) in the middle of the night.

Ours (with a salt chlorine generator) runs automatically from 10 in the morning unitl 7 at night- 9 hours.

8 hours in the summer, 2-3 in the winter. We also have a SWG running around 70% and we keep chlorine levels around 4.0 as well. We have a 23,000 gallon pool with only a .75hp Jandy pump.

just had my pool installed.was told to run the filter 12 hours a day.the timer is set from 7 am to 7pm.was also told that its better to run the filter during the day while the chlorine is hot.here in the northeast it will be closed sometime in september.

Our SWG is at 30%, the pump runs from 2pm until 9pm. I turn it on earlier if I have a day off or on weekends. The chlorine stays between 4-5. Our pool is the same size as mdoceanblu's.

During the winter, we run it about the same but reduce the SWG to
