Rinse mechanical media on a regular schedule; replace biomedia and cartridges per the manufacturer (often many months apart).

Description

Ceramic rings are porous biological filter media that provide a large surface area for beneficial bacteria colonization. They are long-lasting and rarely need replacement — just rinse in old tank water during maintenance. Suitable for canister filters, sumps, and hang-on-back filters.
