Dymax Filter Media Bags

Dymax Filter Media Bags offer a practical solution for containing and organizing filter materials in your aquarium. Constructed from washable, bleachable nylon mesh with a durable plastic zipper, these bags accommodate fine media like coral sand, resins, and specialty filtration products. The extra-fine mesh prevents material escape while remaining easy to clean and reusable. Available in three sizes—Small (14 x 20cm), Medium (18 x 25cm), and Large (27 x 30cm)—and three mesh grades (Extra Fine, Fine, Coarse), you can match the bag to your specific filtration needs. Safe for both freshwater and saltwater setups, these versatile bags simplify maintenance and extend the life of your filter media.
