Stop Washing Dirty Filter Socks Forever
Nobody likes dealing with a laundry bucket full of dirty, foul-smelling 7-inch filter socks. Traditional filter cups choke flow quickly, and automated fleece rollers come with high price tags and complicated installations.
The VCA NOSOK™ 7" lands right in the sweet spot. It delivers the high-surface-area filtration performance of a filter sock with the zero-laundry convenience of disposable filter floss—giving you crystal-clear aquarium water without the hassle.
Key Features & Benefits
-
No More Sock Laundry: Simply wrap cheap, standard filter floss around the inner filter core. When it's full of detritus, toss the dirty floss, re-wrap a fresh layer, and drop it back in.
-
Superior Surface Area: Unlike flat-bottom filter cups that clog in days, the NOSOK™ wraps filter media 360 degrees around the inner cage, maximising surface area and keeping water flowing freely.
-
Reusable 255-Micron Mesh Screen: Includes a heavy-duty nylon screen insert that unrolls completely flat. When it gets dirty, simply rinse it under tap water in seconds and reuse it endlessly.
-
Versatile Setup Options: Tailor your filtration strategy to your reef's specific needs—run floss only, mesh screen only, or combine both for maximum mechanical polishing.
3 Flexible Setup Configurations
-
Filter Floss Only: Wrap inexpensive filter floss around the inner core for sock-like particulate capture. Just toss and replace when clogged.
-
Nylon Mesh Screen Only: Insert the included 255-micron nylon mesh screen into the cage to trap free-floating debris. Pull it out, unroll flat, rinse under running water, and put it right back.
-
Floss + Mesh Combination: Wrap the core with filter floss as your primary line of defense, backed up by the mesh screen inside for dual-stage mechanical filtration.
