ASTRALPOOL SILICA SAND 25KG

Sand is the filtering medium that the pool filter has inside. When water enters the filter, it passes through the sand and leaves the particles suspended in it. It is important to carry out good maintenance to ensure the quality of the filtration. There are different granulometry of sand and new filtering media such as vitreous.

Undoubtedly, sand or silica are the most used materials in domestic pools. Sand traps dirt from the water as it passes through the pores formed in its irregular shape. As a disadvantage, sand requires maintenance because, with its use, channels can form that cause water to pass directly into the pool without being filtered. Another disadvantage is the ability of sand to retain bacteria and microorganisms, which can cause them to multiply inside the filter.
