Pool filter sizing
Do you need a new pool filter? This commodity volition help you to choose the right size of filter for your pool. The starting time affair to know when it comes to puddle filter sizing is that there are three different kinds of filters that you lot can use on an inground puddle. Above ground pools tin can also use any of these iii kinds of pool filters, plus some very pocket-size higher up ground pools as well take the pick of using a very small newspaper way filter similar you might observe in a hot tub. The three types of inground pool filter are:

Cartridge filters

Sand filters

DE filters (diatomaceous earth)

At that place is no "all-time pool filter" for every swimming pool. Each filter has their advantages and disadvantages and you need to determine which is the best fit for your needs. In one case y'all accept determined which filter fashion you want so you can accurately determine what size (and make / model) is going to match up well to the size and demands of your pool. Before starting with filter sizing calculations you first need to learn nigh the potential filtering abilities of each manner of filter. The particulate size that each filter tin can remove from the water is the outset consideration.

DE Filters 1 - iii Microns - Diatomaceous world filters are used heavily in some areas of Northward America while other areas take about no DE filters at all. DE filters have the ability to remove the finest particulate from the h2o. DE filters can filter debris between one to three microns in size.

Cartridge Filters five - 15 Microns - Cartridge filters are the next best pool filter style for removing fine particulate still even under ideal circumstances they are not as effective at removing fine material from the water besides as a DE filter.

Sand Filters - 15 - 30 Microns - Sand filters are the oldest type of pool filter and the most commonly used on residential pools. Sand filters are able to remove droppings down to xv to 30 microns in size which makes them much less effective than DE or cartridge filters.

So how important is filter particulate size for your pool filter? Well, considering that sand filters are the least effective at removing small debris and yet are still the nigh popular puddle filters this should tell you a lot nearly what "the best pool filter" is for your pool. The truth is that whatever of these pool filters easily have the ability to keep your water clean and clear. A sand filter and a DE filter will both exist able to keep water clear if they are sized properly for your pool, and during the day yous would non be able to notice much of a difference with the water...if at all. At night however, with the lights on in the pool, a DE filter would exist more effective at removing fine particulate that you tin can see floating around in the illuminated h2o at night. So is it important to have the cleanest, clearest water in your pool that is possible, or would you lot prefer the most toll effective option that will keep your water clear and swim-able? The truth is that the best pool filter is not the one that removes the about debris. Certain this is important, but the maintenance schedule for each filter type is likely fifty-fifty more important than filtering particulate size.

Pool Filter Maintenance

pool filter maintenance A very of import part of the process of choosing the best filter for your pool is to understand the differences between each kind of filter so that yous can pick the one that suits your needs the best. Once you lot take considered the pros and cons to the three types of filters you volition be able to brand an informed determination every bit to which you desire.

Sand Filter Maintenance - Sand filters require "dorsum washing" as the only existent maintenance. This is a five infinitesimal long procedure that must exist completed every calendar week to two weeks depending on your pool system. This process merely reverses the direction that the water is going through your filter and sends the resulting h2o away through a "waste material line" attached to your filter. This eliminates the accumulation of debris from where water normally first enters the filter tank. Without this process your pool pressure would climb steadily and eventually h2o would not be able to pass through the filter. While this process does not accept very long, it does require some effort and it does crave to be done on a regular footing. Information technology also requires that y'all regularly pump off some water in your pool and then you would need to replace it with fresh fill water. If you lot live in an area with drought or water shortage conditions, then this alone would exist a good reason to avoid this filter type. Also, if you have a common salt water pool and live in an area which does not allow for draining common salt pools to the street, then back washing might be a trouble for you. If y'all want the cheapest puddle filter possible that will last a very long time also every bit keep the water make clean and articulate in your puddle, plus yous don't mind a five minute procedure every few weeks, so a sand filter might be only what yous are looking for. Other than changing the sand every vii to 10 years there is non much else to caring for sand filters.

Cartridge Filter Maintenance - Cartridge filters crave less regular interaction from you, the pool owner, than any other blazon of filter. While information technology does non have the small particulate power of a DE filter, a cartridge filter is still around 3 times better than a sand filter...but effectually 3 times as much money as i also. If you tin can afford a cartridge filter, and you can likewise afford to replace the rather expensive cartridges every three to five years or so (at all-time), then a cartridge filter is considered by many world class pool builders to be the best pool filter overall. A DE filter can clean finer debris from the water, marginally, merely a cartridge filter can oft get an entire swimming season (six months) without needing to have the cartridges cleaned. Nearly cartridge filters simply need to take the filters cleaned once every six months of use or so (regionally, some areas in the USA utilize small filter cartridges and clean them much more oftentimes). Pools with a lot of debris and leaves in them might require more filter cleanings but this volition still be less overall work than dorsum washing a sand filter or periodically charging a DE filter. Cartridge filters also take a vastly superior flow efficiency than sand filters which allows them to exist paired with larger pumps and much college flow volumes than what a sand filter tin adjust. This makes cartridge filters a much more efficient pick than sand filters and more suitable for the powerful variable speed pumps that accept recently started to be available on the residential pool marketplace.

DE Filter Maintenance - Diatomaceous earth pool filters are able to filter the finest particulate size from the water of any of the three types of pool filters. For many people this factor lonely then answers the question of which is the best puddle filter. It is however also worth considering that DE filters require the near time spent on maintenance in order to continually monitor their pressure, charge them with DE, as well equally periodically strip them apart to clean the DE grids. DE filters require regular back washing similar a sand filter, only they also crave you to periodically open the filter and make clean the internals just like a cartridge filter. Experienced pool technicians will tell y'all that stripping a DE filter does not have long, and information technology does not need to, just the average pool owner will take much longer to perform the same chore than someone who does it for a living. You may have heard about some people who eat DE for health benefits. It is important to differentiate between nutrient form amorphous DE, and pool filtering grade crystalline DE. Crystalline DE every bit used in pool filters contains upwardly to 70% crystalline silica and tin can exist very dangerous to work with. DE filters require regular charging with DE to keep them operating properly so if you would prefer to avoid storing and using crystalline DE then that is a adept reason to choose a cartridge or a sand filter. These reasons are why DE filters are less popular than sand or cartridge filters despite existence able to filter finer material from the water.

The corporeality of filter maintenance that you need to practise will depend on the unique conditions that your pool is exposed to. If your pool gets a lot of use, and the people who use it habiliment lots of sunscreen and makeup and pilus products, plus you take a lot of trees (and leaves) on your property almost the pool, and then yous will have a more enervating filtering requirement than someone with no trees, whose puddle does non get used very much. In the instance for all filters, you know it is fourth dimension to clean the filter when the force per unit area of the system goes up seven PSI above the clean operational pressure of the arrangement. You can read more most why keeping your pool pressure down really saves y'all a substantial corporeality of coin in this article about how to make your pool more than energy efficient.

How To Choose The Right Size Filter

If yous want to know how to choose the right size filter for your pool you lot need to know which of the 3 filter types you want. The next affair you need to know is the volume of your pool. This information will help you to determine how much h2o your filter needs to be able to handle each day. This is where the subject of "water turnover" comes into play. A turnover of h2o in your puddle refers to the entire book of your pool passing through the filtration organization. For this instance allow'due south assume a puddle is 10,000 gallons. One turnover of this pool would exist 10,000 gallons, two turnovers would be 20,000 gallons and 3 turnovers would be thirty,000 gallons and and so on.

The reason why turnovers are of import is considering your pool water needs to be filtered every day to keep the water articulate and help the chemicals to go along the water safe. The problem is that you can not filter all of the pool water in social club...some of the water in the pool will become filtered twice while some will not get filtered at all. There is a mathematical calculation behind this which reveals how much y'all need to filter the water in your puddle in guild to finer get all of it through the filter at least in one case:

1 Turnover = 63% of water volume

Second Turnover = 86% of h2o volume

Third Turnover = 95% of water book

Fourth Turnover = 98% of water volume

It is generally accepted that three turnovers per solar day finer "filters all" of your pool water. This means that in order to make certain you filter all of your water every twenty-four hour period you should be sending three times the volume of your pool through the filter every 24 hours. More than filtering would be better, just only marginally and so, where as less filtering will leave a relatively large amount of your water each day unfiltered. So what does this mean? Volition your water turn dark-green if y'all only filter your pool volume twice every day? No, probably not. Puddle owners tend to run their system much less than three turnovers per day, and largely these pools are "fine". The less you lot filter the pool water the more than you are relying on chemicals to clean the pool. You tin try to get away with less filtering only this will accept a cyberspace issue of increasing the chlorine that you need to use, which in plough will also increment the amount of reactionary chemical adjustments that your puddle needs in general. So you can filter your water less than 3 times every day, however this is less than recommended past manufacture health and safety standards.

Instance pool - If a pool has a volume of x,000 gallons then you should buy a filter that can handle up to xxx,000 gallons every 24 hours. 30,000 divided past 24 gives you 1250 gallons required per hour. 1250 divided by sixty gives yous 20.83 gallons per minute of menses. In this instance a 10,000 gallon pool would need a filter capable of filtering up to 21 gallons per infinitesimal. This assumes the pump is running 24 hours per twenty-four hour period. If yous want to run your pump less than this merely triple the volume of your pool, and divide by the number of hours that yous want to run your pump for.

Puddle filters all have a maximum designed flow rate. This is the maximum water flow they can handle under normal atmospheric condition. One time y'all know how many gallons per 60 minutes you need your filter to handle y'all tin so compare it to the maximum designed flow rate. Yous tin can have less menstruation in a filter and that is not a problem. In fact slower h2o filters meliorate and more efficiently in all three of the filter styles. If you demand 21 gallons per minute capability then but choose any filter that has a higher maximum designed menses rate than 21 GPM. There is cypher wrong with a filter that has a maximum designed flow charge per unit of 80 GPM being used for a puddle that needs merely 21 GPM, only you never desire to exceed the maximum designed menstruation rate for your filter.

Matching The Pump & Filter Together

Y'all now know that you lot need to filter iii times the volume of your pool every 24 hours, likewise equally how to catechumen this number to a gallons per minute number. Yous as well know that you need to check the maximum designed flow rate for your filter to make sure that your filter tin handle the GPM that you need. In that location are ii more than considerations that you demand to factor in before you can decide on a filter model. You need to know how much water your pump can move (in GPM) too as the size of pipe that your pool is made out of. In full all of this information will go yous close to finding the best filter for your pool.

Pump Flow - There are a few dissimilar reasons why y'all might need to know how much h2o your pump moves through the system. This volition completely depend on your unique situation. A single speed pump for instance, which most pools yet apply for the primary filter pump, simply has 1 speed and this speed tends to be a lot of water. If yous have a unmarried speed pump y'all demand to know how much water the pump will move to make sure this is not more than than the maximum designed catamenia rate for the filter you lot are considering. If y'all take a variable speed pump, similar you should, so exceeding the maximum designed flow rate is bad, but you too have the power to run your pump at lower and safer speeds. A larger concern with a variable speed pump is the minimum menses rate for the filter. Not all filters have a minimum menstruum rate requirement...but some do. Make sure to double check this specification with the filter you are looking at.

Pipe Size - The other consideration is the pipe size that your plumbing system is made from. Many pools have 1.5" pipage which is barely acceptable for modern pond pools. In reality the side by side best 2" size is nevertheless leaving a lot of room on the table for increased efficiency. If you accept 1.5" pipe this ways water needs to travel faster through the piping which ways greater turbulence in the line and resistance to catamenia. ane.v" pipe has a soft limit of 44 GPM across which there is a logarithmic efficiency loss that prevents you lot from moving more water even with a larger pump. If you need more than 44 GPM and y'all accept 1.5" plumbing lines then your system was poorly designed and you should wait at upgrading pipage size to ii" or larger on the unabridged pool if possible. Unless you upgrade the entire plumbing organization size it volition always exist bottle necked by the modest bore piping you do not upgrade. It is worth noting that the greatest concentration of fittings and flow restrictions in a puddle are located on the equipment pad. If you tin upgrade the equipment pad to 2" pipage this will amend the period efficiency of the puddle arrangement as a whole even if you withal accept smaller pipe restrictions underground.

All of this data allows you to understand what your puddle filtration schedule should be, and how close you tin can get your puddle to this schedule. If you choose a filter that tin handle three times the pool volume daily, as well as have a maximum designed menstruation rate that is greater than your expected system period charge per unit, y'all tin can cull a practiced filter. The pipe size and flow rate calculations helps you lot to make certain that your puddle organisation is designed correctly (many are non, specially older pools) and that your filter tin handle the actual period that your pump creates. If yous follow these steps y'all will get a suitable filter for your pool and information technology should last for decades before you lot demand to remember about getting another one.
