Micron Filter Sock 4.5x7 inch Rectangular by Eshopps
Micron filter bags are an important part of mechanical aquarium filtration. They help reduce the amount of ammonia-producing organic matter and also prevent larger objects such as sand, crabs, and snails from damaging pump motors. The Eshopps 300 micron sock can be added to any existing sump. Rectangular Bags offer two times more filter space than round models - perfect for larger sumps or for those wanting to change filter socks less frequently. Compatible with Eshopps Micron Bag Holder PF Series (PF-LG, PF-XL), RS Series (RS-200, RS-300) and R-Series (R-200, R-300).
