Seachem Laboratories Aquarium Filter Sock with Plastic Collar, White, 4 in x 12 in, Small

Keeping your tank water clear is easier when the right mechanical media is doing the heavy lifting, and the Seachem Laboratories Filter Sock with Plastic Collar in white is made to be an integral addition to any sump and overflow system. This is the small size, measuring 4 inches by 12 inches, a great match for compact sumps and tighter fittings. It is built to strain particulate out of the water before it cycles back to your fish, so your aquarium stays cleaner with less effort from you.

• Carries a 100 micron rating for exceptional particulate removal as water filters through.
• The compact 4 inch by 12 inch small size fits neatly into smaller sumps and overflow chambers where space is limited.
• Welded seams stay intact over time, and unlike the threaded seams on similar products, they will not break down with use.
• A singed finish reduces wear and helps prevent loose fibers from being released back into the water column.
• The plastic collar simplifies installation and slots easily into standard sump fittings.
• That sturdy collar holds the sock open so water is funneled through the media instead of slipping past it.
• Catching debris early with mechanical filtration eases the workload on your biological and chemical stages.
• The white fabric makes it simple to spot when the sock is loaded and due for a rinse or change.
• Well suited to marine, reef, and freshwater setups that call for polished, particle-free water.
• A smart choice for smaller systems where a full-size sock simply will not fit.

For nano reefs, compact freshwater sumps, or any system with limited room, this small Seachem filter sock gives you reliable mechanical filtration in a size that actually fits. Drop it into your sump fitting, let it pull the particulate out, and keep it part of your routine maintenance for steadily clearer water.
