The first important step in maintaining a clear and clean swimming pool is getting a properly sized pool filter and using a TCCA tablet.
The pool filters are responsible for removing debris and dirt, allowing bromine and chlorine or even any other existing sanitizers to place a significant focus on destroying bacteria that might be in the water.
You actually need to check the sizing recommendations on filters carefully that you intend to consider buying.
It can even be better if you consider a bigger one if you can really afford it since small sized ones are not always making work effective, especially when trying to clean the edge between two different sizes.
Choosing the right size plays a huge part in keeping your pool clean, and there are also plenty of other cleaning services like those on this belgian website that you should consider engaging to keep your pool in top condition.
There exist three pool filter types in the market, i.e., Cartridge, diatomaceous earth, and the sand type.
They all can do the best job for your pool.
Having said all this, you need to know that there is no best filter that will perform every kind of application; it’s the owner to choose what he/she will prefer.
By this, you will have an idea of the best filter type that will work best for your pool and keep everyone swimming.
Let’s have a look into each and every type of pool filter we have named.
Sand pool filters
Sand Pool filters are the most common pool filters in the market, and actually the oldest.
For this filter, its filter tank is filled with a particular sand grade that we usually call #20 silica sand, and it is actually available at most local stores or gravel and sand yards.
Water will be entering the tank and after that get pushed down, passing through the sand that will be trapping debris and dirt.
This water will travel all through to the bottom-most of the tank where it enters the laterals.
The water is thereafter returned into your swimming pool.
You will be able to see the laterals at the tank bottom in the cutaway image.
The pool waters will be filtered through the pool’s slotted pipes and then moves to the central tube where it will then be returned to the swimming pool.
These kinds of filters are capable of filtering particles that are of the size 20-40 microns.
Actually, this is what makes them technically the least effective one among the other existing swimming pool filters in the market in terms of the size of particles removed.
Also, these are the most accessible pool filters to be maintained that just need backwashing or even just cleaning to carry out its function of removing dirt from the filter as the pressure gauge reads between 8-10 psi as the startup meter reading.
At this time, any buildup can no longer be removed by backwashing.
Here, the sand particles would have turned smooth, making them unable to trap any debris, and you now need to replace it to carry out its function.
Averagely, this can be done at a period of between five to seven years, but then this can be a bit sooner for undersized sand filters.
Cartridge pool filters
They have been given this name since they contain a spun pleated polyester cartilage that looks in a similar way like the air filters you might at one time come across in cars.
For this filter, water is forced via the creases of the cartilage, and debris of sizes as small as 5-25 microns will, in turn, be trapped.
This is actually an improvement over the sand filters.
These pool filters are also popular as they require low maintenance costs.
Bigger filters of this kind will only need to be cleaned whenever its pressure is 8 to 10 over the regular required standard readings or even at a period of 6 months interval.
You need to know that some of the filtering ability of this filter is usually lost each time the swimming pool cartilage is cleaned.
This will eventually lead to the buildup of debris and oils.
There might reach a point they can’t be removed requiring it to be replaced.
Replacement of this filter cartilage can be done at an interval of between 3-5 years.
Filter cartilage replacement varies typically in terms of their cost, but then, averagely, a new one can be obtained at a price of up to $ 100 each cartilage.
While out there looking for these cartilages, you will find out that some filters may be having many cartilages; you will need a professional to guide you for this.
Diatomaceous pool filters
Normally abbreviated as D.E, they have designed to remove particles of sizes of up to between 1 to 3 microns.
This is the smallest sized particle that we can see and thus making them the most effective types in the market.
This type of filter usually contains either grids or fingers that have been well covered by diatomaceous earth fine powder.
This is the powder that is responsible for carrying out the filtering function of this filter.
The powder usually is not sold together with the filter but rather itself, and it is actually added into the filter by directly pouring it through a skimmer.
Just in the same way as the sand filter needs to be back-washed, the diatomaceous pool filter also needs this when its pressure gauge is seen to register a reading of between 8-10 psi above the standard reading.
This process flushes typically most of this powder outwards.
This shouldn’t be back-washed into sanitary sewer systems or streams but instead, follow the correct procedure for doing this.
After this, you need to add a new powder application to the filter through the skimmer.
This is actually the most efficient pool filter to consider, but it is much more expensive.
While in the market buying pool filters, there are many factors that need to be considered to help you make the right choice.
Below are some of them.
The size of the filter is the first thing you should consider.
Look at a turnover rate in terms of gallons per minute and then decide on the best one for you.
Considering a larger one can be a reasonable consideration if you can make to afford it.
Next is deciding how clean you need the pool water to be.
For personal use ones, you usually not need frequent cleanup, but then it is good you do it as much as you can.
Lastly, you need to determine the maintenance time cost and time you will need to put into your filter.
