It is a question a lot of pool owners have and a question that we have the answer to! A pool filter should be run for a minimum of 6 hours after shocking a swimming pool. This is to allow the filter to clean the water and give the shock enough time to fully mix with the pool water.
Answer: Generally you will want to wait at least 4 hours, but ideal is waiting for one complete turnover of the water (the time it takes all the water to go through the filter).
The wait times between adding pool chemicals is usually around 10 minutes each, as that is also sufficient time for the chemicals to mix in the water. Users also under normal conditions can swim roughly 10 minutes after adding chemicals.
In the industry it is recognized to have the pool run for 3 hours at a bare minimum up to 24 hours. 24 hours really is overkill but it'll ensure the water is completely mixed with the chemicals.
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.
Vacuuming After Shock
Shock the pool with either the liquid or granulated chlorine shocks. Let the filter run for 24 hours before adding any other chemicals.
The rule of thumb is generally 8 hours, although it could be anywhere from 6-12 hours, depending on your pool's size. Each pool is unique, so to keep your pool pump efficient and effective, you need to figure out exactly what your pool's turnover rate is.
The Short, Short Version. Test Chlorine levels at least twice per week. Also make sure to test after heavy use or rainfall, as Chlorine levels have likely been depleted. Pool chlorine is responsible for sanitizing your pool and hot tub water to make it safe to swim.
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.
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.
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.
It Should Not Be Done Together
This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM.
The best time of day to shock your pool is in the evening. This is because the sun's rays can affect the effectiveness of the chlorine by dissolving it too quickly, before it has a chance to rid the pool of contaminants and clean the water.
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.
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.
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.
You might have an infestation of algae, fungus or bacteria that can deplete normal chlorine levels and it is possible for this to occur without many visible signs. Your pool may appear to have a dusty look on the pool bottom. If you brush it and it clouds the water, then it is most likely a Mustard Algae.
Liquid chlorine and granular shock have the same active chemical that sanitizes your pool, what changes is the strength and the way you use it. Liquid chlorine is less costly, unstabilized and comes in liquid form. Granular shock is stabilized and comes in a solid form that dissolves in your pool.
Bottom line, the filter must be backwashed on a regular basis to ensure that your pool water is clear. "When do we need to backwash?" - It is recommended to backwash your filter once every 4-6 weeks of regular use.
Cleaners aren't meant to stay in the pool 24/7. This is true for all cleaners. Pressure side cleaners run on a schedule every day so why take it out? Leaving the cleaner in the pool 24/7 increases its exposure to corrosive chemicals in the water, such as chlorine or shock.
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.
We recommend that our customers run their pumps rain or shine UNLESS we have an electrical storm. In that case, lightning could strike an outside circuit, which could damage your pump and other equipment. If you're worried about lightening, turn the pump off or shut off the breaker.
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.
