How are they used?
Answer by • May 03, 2022
Filter socks are usually placed on the receiving end of the reef tank's overflow pipe. In some sumps, the overflow pipe drains into an overflow chamber then overflows into a filter sock chamber where the filter socks receive the water and filter it before going through the sump and returning to the tank.
