Aquarium & Pond Filter Foam: PPI, Polyether and Biological Filtration
Aquarium, pond and aquaculture systems rely on foam for mechanical trapping and as surface area for beneficial bacteria. Polyether reticulated foam is usually specified because it resists hydrolysis and drains quickly in continuous water contact.

Mechanical and biological roles
Coarser PPI foam catches debris early in the flow path. Finer stages polish water and increase surface area for biofiltration. Many keepers stack multiple PPI grades in one canister or sump.
