Explore the filtration range

• Air-driven sponge filters: Serenity, Bioscape, Pet Worx and Huey Hung models, plus an UP Aqua sponge filter with a ceramic-media compartment. Check the air pump, airline and other connection requirements, and what is included.
• Filter socks and accessories: options from Red Sea, Waterbox, Aqua One, Betapet, Eco System and Dymax, with selected holders and silencers. Compare felt or mesh construction, micron rating, rim diameter and sock length.
• Roller filters and replacement fleece: selected ClariSea and Bubble Magus systems and rolls. Match the replacement roll to the exact filter model, generation and required width.
• Sponge sheets, wool and prefilters: cut-to-size materials, Pond One pump prefilter sponges and Ocean Free Hydra 50 replacement foam. Check dimensions, density and equipment compatibility before choosing.

Choose the right filter or replacement media

Sponge filters collect particles and provide a surface for beneficial bacteria to develop. Filter socks, wool and roller fleece are mechanical filtration materials used to capture suspended debris. They are not interchangeable with chemical filter media, and plain sponge or fleece should not be treated as a way to remove dissolved chemicals or disinfect aquarium water.

Choose equipment for your tank's volume, livestock, waste load and filtration layout. For sump accessories, measure the holder opening and available depth rather than relying on the nominal sock diameter alone. Follow the manufacturer's cleaning and replacement instructions, and monitor media for clogging.

Selected larger products have additional delivery charges. The Bubble Magus G2 Large roller filter is listed as a special-order item; check its listing for availability and ordering details.
