Why is it important to have a good filtration system for the pool?
To ensure a long and quality lifespan for the pool, it is important to carry out constant maintenance and care of its structure and water. Depending on the type of pool you have and the material it is made of, its care will vary. However, cleaning and disinfecting the water are key factors to ensure a healthy swim free of algae and bacteria. For this, it is important to have a good filtration system.
The filtration system consists of two main elements: the pump and the filter. The pump is responsible for drawing water from the pool, directing it to the filter and, once the filtration process is complete, returning it to its original place. On the other hand, the filter's function is to clean the water and remove the debris and impurities it may carry.
The water filtration process must be carried out frequently and daily to maintain an optimal water condition that allows swimming. A cleaning cycle, the time it takes for all the water to be filtered, will depend on several factors:
Pool size and water volume.
Pump suction power.
Filter filtration capacity.
Filtration power of the filtering material.
Variety of filtering agents
There are several filter options on the market so you can choose the one that best suits your needs. One of the main differences between filter models lies in the filtration capacity of the filtering material they use. The filtering agent is the substance used to filter the water and is responsible for retaining dirt particles in the water. Although all of them offer great cleaning results, you will notice that the particle retention level varies depending on the filtering material.
Silica Sand or Gravel
The most popular and common element among sand filters. It can be found with different grain sizes, meaning the grains can be finer or coarser. The grain size will depend on the cleaning needs of each pool. Sand retains dirt in the pores formed between its grains due to the irregular shapes they have. However, a disadvantage of this type of media is the possibility of retaining bacteria due to its high porosity, which can cause the proliferation of microorganisms inside the filter.
Most popular and widely used material
Optimal results due to its quality-price ratio
High porosity that allows bacteria to proliferate within its pores.
Filtering Glass
Made from recycled glass, it is the main alternative to silica sand. A highly effective and environmentally friendly material derived from old glass elements. The angular glass particles are composed of silica, a material with superior permeability that facilitates washing and cleaning. It should be noted that, having a smooth and less porous surface, bacteria accumulation is reduced. It boasts long durability and very attractive efficiency as it requires minimal water and disinfectant products for maintenance.
High efficiency
Environmentally friendly
Long durability
Low density: less quantity needed than sand and offers better results
Diatoms
Diatoms come in a powder form derived from fossilized sea elements, such as shells and silica secretions from small marine creatures. It has the highest filtration power on the market, offering excellent cleaning and water disinfection results. Its use guarantees a crystal-clear pool. However, one of its disadvantages is its high price, which increases due to the need to recharge the filter periodically. This type of media can only be used with filters named after the material.
Most effective material
Higher price
Incorrect handling can pose health risks
Zeolites
Zeolites are aluminosilicate minerals, suitable for diatomaceous earth filters, highly porous and of natural origin. Their quality is comparable to diatoms but at a more affordable price. They are suitable for sand filters, differing in that they require fewer chemical products for cleaning, thus saving costs on water and disinfectants. They have the advantage of removing ammonia particles present in the water, reducing the chemical smell of your pool and allowing a more pleasant swim. They also reduce chloramines that cause skin discomfort and eye irritation for swimmers.
Quality similar to diatomaceous earth powder
Lower price
Removes ammonia particles from water
Reduces chemical odour
Aqualoon or Fibalon
The most recent and innovative alternative as a filtering medium. Aqualoon was developed to create highly effective water cleaning products with the added advantage of being environmentally friendly. With a very striking appearance, they consist of polyethylene balls that replace the typical sand or glass media. Their high efficiency allows filtering very small residues and they have a very long lifespan. Aqualoon balls can be washed and reused several times, always offering the best filtration quality.
Ecological and environmentally friendly product
Their polyethylene balls can be reused multiple times
Recyclable after their lifespan ends
Works in a sand filter
Silica sand or filtering glass?
Although there are more types of media, the most common are sand and glass. There is a greater variety of manufacturers distributing their brand of this type of filtering material and a wide and extensive market of sand filters (suitable for use with sand or glass media). Therefore, it is much easier to acquire these types of filtering products.
Filtration capacity
Broadly speaking, the material that is most effective at filtering dirt particles is glass. It is a recycled and ecological element that has no pores, which facilitates the retention of debris without the risk of becoming a place where bacteria can proliferate. Unlike sand, which has high porosity due to its irregularly shaped grains, glass tends to have a very smooth and uniform surface, resulting in a very low porosity level. As a consequence of its physical appearance, better filtration results and clearer water are achieved.
Durability and maintenance
Another advantage of glass is its great resistance. Due to its homogeneous consistency that hinders microorganism accumulation, minimal chemical products are needed to disinfect the material. Therefore, it suffers less wear and its lifespan is extended. Choosing glass means saving on disinfectants, washing water, and energy. Sand, on the other hand, has an approximate lifespan of about 5 years, much shorter than the 10 years glass can last. Additionally, it requires frequent maintenance to check the condition of its grains, as they tend to compact and lose effectiveness.
Density
At first glance, by quantity and price, it may seem more cost-effective to buy sand instead of glass. But in the long run, you will invest more in sand due to the larger quantity the filter needs and its much shorter durability compared to glass. Sand is a denser product than glass. This means a heavier load is needed in the filter to meet its filtration objective. Since glass has a lower density than sand, it requires 15% less product, which implies savings on the load. A bed of 25 Kg of silica sand corresponds to 20 Kg of glass.
Additionally, you can find glass in different grain sizes to achieve a filtering bed of different thicknesses and obtain a more favourable result in water filtration.
| Grade | Grain size | Recommended quantity | Recommended quantity |
| Filter diameter < 900 mm | Filters diameter > 900 mm | ||
| Grade 1 | 0.5-1 mm | 80% | 60% |
| Grade 2 | 1-3 mm | 0% | 20% |
| Grade 3 | 3-7 mm | 20% | 20% |
Factors to consider before choosing a filter
When choosing a filter and its filtering material, it is important to consider the volume of water to be cleaned and, therefore, the size of the pool. In terms of filtration efficiency, diatomaceous earth filters perform the most efficient filtration process, while sand and glass filters come second. Cartridge filters would be more recommended for smaller pools with much lower water capacity.
Another difference in filters is the location of the selector valve. The valve allows activating the filter's operating mode and usually has the following modes: wash – drain – recirculate – backwash. Depending on where the valve is positioned, access to the inside of the filter will be easier or more difficult. Also, the valve's position implies that the filter chamber has a different diameter, with the side valve allowing for a wider space.
Below, we show you a comparative table of various filter diameters so you can observe the differences each presents.
| Model | Diameter (mm) | Flow rate (m³/h) | Recommended pool volume (m³) | Connections | Sand load (Kg) | Glass load(Kg) |
| Filter 400 | 400 | 6 | 48 | 11/2 " | 60 | 50 |
| Filter 500 | 500 | 9 | 72 | 11/2 " | 100 | 85 |
