Keep your tanks water clean and polished with Eshopps 300 Micron Filter Socks!
The rectangular bracket design works perfectly with the Cube Medium Refugium Sump, or can be implemented in any custom sump sock holder. The 300-micron rating allows large visible pieces of detritus and other foreign materials to be collected while water and smaller particles will flow through the sock, which is a great balance between polishing and flow rate.
Sock Length: 13"
Opening Size: 7" x 4.5"
