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.
Filter socks are normally placed immediately in the sump keeping large particles, but also critters that could have gone down your overflow from damaging pumps and other expensive pieces of equipment. It is suggested to change or clean the filter sock every 3 days to keep organics from breaking down into ammonia or other toxic compounds.
