Pond Filter Media

About

Pond filter media include filter wool, mats, sponges, gauze, ceramic rings, bio-balls and lava rock. Alfagrog, Pond Matrix, biological blocks, activated carbon and media bags extend the collection across mechanical, biological and chemical filtration. Coarse and fine mechanical media capture different sizes of debris, while porous biological materials provide colonisation surfaces for beneficial bacteria. Media bags organise loose products within the filter, supporting distinct stages of pond-water filtration.
