The top 5-10 cm's of wet sand require continuous flow of oxygen rich water. The colloidal and dissolved impurities are removed through a process of adsorption and the organic materials are converted to salt during the same process. The filtered water collects at the bottom of the sand filter through a pipe system. The whole process allows a bio film to form in the fabric filter at the top of the sand bed.

Is sharp sand the as pool filter sand?

No, sharp sand and pool filter sand are not the same. Sharp sand, also known as concrete sand, has larger, angular particles and is often used in construction and landscaping. Pool filter sand, on the other hand, is specifically graded silica sand designed for use in swimming pool filtration systems, providing effective filtration due to its uniform particle size and smooth texture. Using the wrong type can affect pool water clarity and filtration efficiency.
