SEACHEM Tidal 35 Foam (2 Pack)
Seachem Tidal 35 Foam (2 Pack)
This product is the original replacement part for the Foam Filter Sponge that is included in your Tidal filter.
The Foam Filter Sponge (for Tidal 35, 55, 75, & 110) acts as mechanical filtration, trapping detritus and other large particulates. The foam sponge provides the first stage of filtration, and helps to extend the life of chemical filtration media, so that the aquarium water is kept clean and safe.
