We’re accustomed to seeing the typically round filter socks, but the new rectangular bracket design from Eshopps is a nifty departure from the traditional version.
Designed for their Cube Refugium Sumps, they can easily be fitted into a custom sock holder where angles might be preferable to the round.
Like most socks, this is a 300-micron rating to pull out the big chunks while letting water flow through. The sock itself is 13 in. long and has a 7 x 4.5 in. opening. They retail for about $12 for one or $30 for a three pack.
