Aquatic Experts 200 Micron Drawstring Filter Socks – Ring-Free Design for Sumps, Saltwater & Freshwater Aquariums, Custom Made in USA (4" x 8", 8 Pack)
200 Micron Drawstring Filter Socks – Ring Free Design: These 200 micron polyester socks use an adjustable drawstring opening instead of a rigid plastic ring, giving you a universal fit for 4-inch filter cups, pipes, and odd shaped sump holders.
Universal 4" Diameter Opening for Sumps & Aquariums: The 4-inch diameter fits standard filter cups and can cinch tightly around pipes or outlets. Perfect for saltwater and freshwater aquariums, refugiums, and sump systems.
High Efficiency Mechanical Filtration for Clearer Water: Interlocking micro denier felt fibers trap uneaten food, fish waste, detritus, and debris. Regular sock changes support clearer water by capturing solid particles before they break down.
Durable, Reusable, and Custom Made in the USA: Crafted to exact specifications and tested for performance. These heavy duty socks withstand multiple cleanings without losing shape or filtration efficiency.
Easy to Clean and Maintain: These durable felt socks can be rinsed or washed for repeated use. Routine cleaning helps maintain strong mechanical filtration and supports a healthy aquarium environment.
