Our Filter Cups will Blow your Socks Off .... Literally!!!

Important Notice: Digital Files Only

Thank you for visiting our site! Please note that we no longer sell physical plastic filter socks for saltwater aquariums. Instead, we now offer digital downloadable STL files, which you can use to 3D print the filter socks yourself. These files include all the sizes we’ve created, including 4", 7" 2.75" Water Box, the 4" Water Box, & Red Sea Sump Size.


I got the replacement filter sheets at Hobby Lobby. They are simply the “9x12
White Felt Sheets,” which you can also purchase online by clicking here.
