It's always best to run the pool pump during the hottest times of the day. The sun is one of the causes of chlorine depletion in your pool. The water moving around helps protect the chlorine from being burnt out from the sun.
It may be cheaper to run the pump at night, but honestly you should run it 1 hour a day per 10 degrees of temperature at least, and it should be during the day. Running the pump at night should only be when you are doing a major chemical treatment such as algae clean-up.
It's best to run your pool pump during the day
Not only does sunlight give fuel for algae to grow, it also destroys your pool chlorine and this is why you should always run your pool during the day!
Overall, the lessons learned today is you should run your pool pump an average 8 hours a day to properly circulate and clean your water. The pump should push your entire pool in gallons in this 8 hour period of time. Residential pool water only needs to be turned over once daily to have proper filtration.
One of the most significant consumers of energy in homes with swimming pools are pool pumps, which keep pools clean by circulating water through filters. Pool pumps can consume 3,000 to over 5,000 kWh per year.
The size of your pool, the efficiency of your pump and filter, and how dirty your pool is are just some of the factors you need to consider. Nevertheless, most pool cleaning professionals would advise against running a pool pump for more than 8 hours a day.
Chemicals that you add to your pool while the water is circulating don't need to be recirculated; they will stay mixed even if you don't pump the water continually. Although it's generally recommended that all the pool water undergo filtration every 24 hours, the pump does not need to run all the time.
The water moving around helps protect the chlorine from being burnt out from the sun. If you run your pump during the night, then the sun has all day to attack the chlorine that's standing still in your pool. That can cause algae fast! It's a great idea to have the pump running when people are using the pool.
Run the pump for 8 hours, every 24 hours. You can also pause in between; there is no need to run it continuously. Ideally, after you shock the pool, be sure to run the pump at night and during non-peak hours, to save on your energy bills.
I think the answer to your question is about 3-6 days. The problem is that the chlorine that you need to keep the bacteria in check is used up more quickly as the temperature rises, the activity increases, and as sweat and other body stuff is put into the pool.
That means that the total volume of your pool water will filter through your system 2 to 3 times per 24-hour period. For a residential pool the water should turn over at least once per day. So, you can feel confident if you decide to run your pool pump for 12-hours a day.
Depending on the size of your pool, we still recommend you run your pump run at least 4-6 hours a day during the fall and winter months. The daily cycle can be divided into multiple cycles, but each cycle should be no shorter than 4 hours, for all the water to pass through the filter at least once.
You should cover your pool every night for several reasons. First off, a pool cover saves energy and conserves water by decreasing the amount of make-up water. Also, it reduces the consumption of chemicals, and finally, it saves a lot of cleaning time since it keeps the debris out of the pool.
To prevent potentially dangerous electrical issues, it's imperative that you turn off the power to your pool equipment — such as pumps, motors, filters, heaters, chlorinators, and lighting fixtures. Even if you turn off the power to your pool equipment, it can still be damaged by wind, rain, and debris.
Depending on the size of your pool, we still recommend the pump run 8-10 hours per day during the hottest summer months and at least 6 hours per day during the winter months.
Depending on how much you have added and the size of your pool, it is generally safe to wait about 4 hours after adding liquid chlorine or until levels reach 5 ppm or lower.
How many skimmers do I need? The Association of Pool and Spa Professionals (APSP) advises that there should be a minimum of one skimmer per 400 sq. ft. of pool surface area.
A good guideline is 8-10 hours a day. On the cooler days and early and late season, you can cut the run time down to 4-6 hours because there is usually less swimmers and cooler water requires less chemicals.
In dry and/or windy conditions, the evaporation rate of the pool increases. Therefore, it is generally beneficial to have a transparent or bubble cover on during daylight hours. In warm, humid conditions the evaporation rate decreases. In this case, it may be more beneficial to leave the cover off during the daytime.
So while a solar cover won't actually 'turn your pool green', it will warm your water by up to 8 degrees, so if the other conditions are right, adding a solar cover can easily accelerate algae growth, very rapidly. You need to get the water balance in your pool right before putting the cover back on.
Algae can become resistant to normal levels of chlorine and can then breed rapidly if the conditions are right. Simply fitting a solar pool cover will not make the pool go green. However, because solar covers will warm the water, they can accelerate algae growth.
Even if you have your pool covered, some debris may still get in it during the winter. For this reason, you should consider running your pump on occasion whenever the outdoor temperature is between 35 and 65 degrees. Around four to six hours should be sufficient to remove debris and help promote good circulation.
