MCCKLE Aquarium Filter Socks, 4-Inch 12-Pack, 9-Inch Long, 200 Micron

MCCKLE aquarium filter socks provide mechanical filtration for sump systems, using 200-micron fabric to collect suspended particles, uneaten food, and visible debris while balancing particle collection with water flow.

• 12 filter socks — keep replacements available for a regular cleaning rotation.
• 4-inch plastic ring and 9-inch bag — sized for a compatible filter sock holder.
• Washable and reusable — hand rinse for repeated use.
• Freshwater and saltwater compatible — made for compatible aquarium sump systems.
• Polypropylene fabric with reinforced seams — constructed for routine handling and rinsing.

As water moves through a sump, suspended debris can collect in a filter sock instead of continuing through the system. This pack is made for aquarium keepers who want a replaceable mechanical filtration option for compatible freshwater or saltwater setups, with several socks available to rotate through routine cleaning.

Will these filter socks fit my sump holder?

Each MCCKLE filter sock has a 4-inch plastic ring and a 9-inch-long bag. It is designed for a sump system with a compatible 4-inch filter sock holder. Compare the holder opening with the ring size before choosing, since the holder must be compatible for the sock to fit.

• Ring diameter: 4 inches (10.16 cm).
• Bag length: 9 inches (22.86 cm).
• Measure the holder opening before ordering.

What do the socks filter from aquarium water?

The MCCKLE sock works as a physical filter: aquarium water passes through the fabric, which collects visible debris and suspended material. The 200-micron filtration level provides a balance between collecting particles and maintaining water flow, making it suited to routine mechanical filtration rather than a chemical filtration role.

• Designed to collect uneaten food and visible debris.
• For use in a compatible aquarium sump system.

How do I clean and reuse a filter sock?

Hand rinse each MCCKLE filter sock with clean water when debris builds up or water flow slows. Check it every 2–3 days so accumulated debris can be cleared as part of regular sump maintenance. Avoid machine washing to help protect the stitching and plastic ring.

• Hand rinsing is the cleaning method.
• The 12-pack provides replacements for a cleaning rotation.

These socks suit aquarium keepers with a compatible 4-inch sump holder who want reusable mechanical filtration for freshwater or saltwater systems. Their 9-inch bags, 200-micron fabric, and hand-rinse care routine make them a defined fit for regular sump filtration and cleaning rotations.
