The Aqua Perlite Filter Media is designed as a direct replacement for DE and cellulose in swimming pool filters. Made from lightweight, expanded perlite, it forms a porous filter layer that captures fine particles and maintains consistent water clarity. Aqua Perl backwashes faster and more completely than traditional DE, reducing maintenance time and water usage. It is chemically inert, non-toxic, and easy to handle, making it suitable for both residential and commercial pool filtration systems.
