Crud Catcher 4" filter sock replacement

Crud Catcher High Flow 4" Sock Replacement

Rigid acrylic filter cup made to replace a 4" filter sock to hold filter floss,  this version has additional vertical flow slots in the sides,  these slots in addition to the base venting create an effective hole of 99% across the diameter of the filter cup,  meaning max flow can pass through the filter floss.

to ensure a laminar flow through the floss without restricting flow you can either place pelleted form of media in the bottom of the cup or large marbles to keep all the available space for flow.  Having the floss sit above the flow slots retains the high flow throgh the cup,

use for filter floss / sponges, or a combo of media you choose,  

Note these do not fit Redsea Reefer tanks,  see the reefer crud catcher
