Our customers tell us every day: there's no substitute for Celatom® diatomaceous earth (DE) and CelaPerl® perlite when it comes to filter aids for swimming pool filters. For over 50 years, EP Minerals' Celatom DE has been the worldwide choice for swimming pool and spa filtration products. EP Minerals unique DE and Perlite have the chemical characteristics that make our products the perfect filter aid for the swimming pool and spa industry.
CelaPerl is a lightweight perlite filter media for swimming pools and spas. Perlite originates from naturally occurring volcanic rock containing water. When heated, the perlite expands to 20 times its original volume and becomes an excellent filter media. CelaPerl is non-toxic and environmentally friendly, providing good pool clarity and improved oil absorption.
CelaPerl is used in the same manner as diatomaceous earth. Simply precoat your filters with the same number of scoops you use today.
