EHEIM coarse/fine filter pad for professionel 4+/5e 350

Fine and coarse filter pads provide both mechanical and biological filtration by evenly absorbing water and capturing particles of various sizes. Their porous structure offers excellent conditions for beneficial bacteria to colonise, ensuring effective breakdown of harmful substances after a short start-up period. The pads are reusable and easy to maintain; simply rinse and squeeze them gently to preserve the bacterial cultures. These long-lasting pads help maintain clear, healthy water in any aquarium filtration system.
