Yep, the Baracuda is not a "clean" look. You can even see my Baracuda from space. I'm going on 2 years with same bladder, foot, and disc that that previous owner had just replaced. I suspect that since I'm only running it 1.5 hours a day for cleaning, these high maintenance parts will last a lot longer than when running 5-6 hours a day as the previous owner's did with a single speed pump. Price though is reasonable for all three - about $50. Pump should also last a lot longer running at lower speeds.

Tinker away and get that time down (and maybe even the rpm) and save several PV panels. I saw AJ from Sun Valley Solar (my vender) a month or so ago (selling a neighbor a system) and he had just replaced his pool pump with a variable speed pump. He was unaware of the pump affinity law. I showed him on my control panel how cutting rpm saves lots of kWh. He said his wife set the controller times up on his pump but now he's going to check his.

A typical homeowner's pool should be fine with one turnover a day for family use.

The 4 turnovers are to get most of the water through the sand filters - meaning mixing and dilution - It is required and your idea is BS.

To get sanitation you need 4 - if you don't care about that then do what you want.

LOL, like I said public pool, fine - 4 hours. But there is no such requirement for the home. When the public health is at issue, one need to provide for people doing "things" in the pool. You put higher levels of chlorine in the pool than a homeowner normally would and want higher turnover. What didn't you understand about my post above? Maybe you should reread it.


LAPDW says this:

Limit the time you run your pool pump during summer to six hours a day, and schedule the run time to avoid operation between 1 pm and 5 pm.

and this:

A pool filter pump is often one of the largest users of electrical energy at a home. You can save energy and money by reducing the operating time of the filter pump.
Time requirements for pool filtering vary from home to home due to differences in pool volume and equipment, the amount of use and environmental factors. As a general rule, one complete water turnover every 24 hours will provide adequate filtering for a non-solar, single family residential swimming pool.

Don't need to reread it - Any pool should have the 4 turnovers - for a public pool it is much higher plus other monitoring requirements.

Public health is different than your families health? More important I guess?

The hours the pump runs are meaningless - the pump capacity has to be part of the equation.

The system can be run at night to achieve the required filtering - again - nothing to do with public pools.

How do you put in more chlorine with more hours? I maintain 1 to 2 ppm at all times - actually my system monitors ORP which is another way to look at it and adds chemical as needed. You are confused about pool systems and how they work.

Although for really heavy use (carrying in lots of dust and mud?), it can be desirable to run the filter while the pool is being used. Same for the heater.

I prefer to run the pumps while using the pool and the balance of the 8 hours at night.

The purpose of the 4 turnovers is that the volume allows about or in slightly in excess of 80% of the pool water to be passed through the filters.

3+ - For your and everyone else's reference one of our members came up with this tidbit off the radio -

the pool sanitation discussion: From the "some things you just can't make up dept.": I heard someone who was talking about not showering w/soap before using a pool say that the average human is wakling around with 164 mg. of fecal matter between their perineal area and their anus (So I guess their taint & balloon knot looks like an open face chunky peanut butter sandwich ?). Not sure I'd like to have the measurer's job on that one.

The four turnovers does not filter 100% of the water but as I remember 80 to 90%. There is always trash getting in a pool un;ess it is well covered.

One can run their pool however they want - just be aware of what good practice is

3+ next time is the last.

I have to admit I am wrong on the turnovers - the 4 turnovers per day is for commercial/public pools.

+3 Golfer - I apologize for for my comment - however, the turnovers per day have little to do with chlorine levels in the water - unless you are using some kind of a manual system.

One turnover does little for filtering the water - it will filter some 58% of the total contents of the pool

HX_Guy, I suggest that you go here (http://www.troublefreepool.com/content/186-show-all_1) and read about pool operations. You will find that what I said is not BS - contrary to what a certain moderator might say.

Determine Pump Run Time

The actual pump run time you need primarily depends on the relative size of your pool, the pump flow rate, the amount of debris that falls into the pool and the use of solar panels (or not). Every pool is different and each pool owner needs to figure it out for themselves. Historically, the rule of thumb has been to run the pump at least 1 turnover per day. However, that has turned out to be a very poor indicator of actual required pump run time.

There are several objectives for pump run time. First, it is very important to add chlorine to the pool in order to reach FC targets. For BBB pool owners, this can amount to only 30 minutes of run time while adding chlorine for distribution, whereas an SWG pool owner may require much more run time depending on the capability of the SWG unit. Second, pump run time is necessary to keep the pool free from debris. This is more about aesthetics which can vary considerably depending on the owners personal preference. Lastly, you may need to run the pump to heat up the pool (solar or other) but that is more an option rather than a necessity.

Next, studies have shown that a typical pool really only needs about 4 hours of run time for proper chlorination, circulation and cleaning. So our recommendation is to start off with 4 hours of run time if your pump is single speed and 8 hours of run time if your pump is capable of running on lower speeds (i.e. two speed or variable speed pump). If this amount of run time is not sufficient to keep the pool clean enough for your preference, then gradually increase the pump run time until it is clean enough for your own tastes. Also, if your controller is capable of split run time, there can be some skimming benefits to splitting up the run time.

However, much more run time may be necessary for significant events such as opening a pool, new pools, or when you are having any kind of algae problem so only reduce run time when the pool has stabilized. One thing to keep in mind is that pump run time does not prevent algae, only maintaining a proper chlorine level can do that.

For SWG owners, remember that the SWG % setting will need to change any time you change the pump run time to hit the FC target. Also, as pool temperatures rise, the chlorine extinction increases so not only will SWG % need to increase but pump run time may also need to increase if the setting is already close to, or at, 100%.

It is important to remember that as the water temperature increases during the summer, chlorine extinction will increase so you may need to add more chlorine to the pool which may or may not require more pump time depending on the method of chlorination. The opposite of this is true for the winter. As water temperature drops and the sun gets lower in the sky, chlorine extinction drops and both the amount of chlorine that is added drops and potentially, the amount of required pump run time can also drop.
