Seachem Tidal 75 Foam Sponge - 2 Pack The Foam Filter Sponge (35, 55, 75, & 110) acts as mechanical filtration, trapping detritus and other large particulates. It is your first stage of filtration, and its use will help extend the life of chemical filtration media. FILTER: The Tidal Foam Filter Sponge acts as a mechanical filter, trapping detritus and other large particles within your tank or aquarium. ENVIRONMENT: The Tidal Foam Filter Sponge is fundamental to maintaining a healthy environment, removing solid or undissolved particles from floating throughout the water. SCREENING: The screening effect of the Tidal Foam Filter Sponge removes particles in the water simply because they are too big to pass through the pores of the filter. DEPTH: The depth effect of the Tidal Foam Filter removes or traps particles that are smaller than the pores of the filter itself by effectively forcing them through the filter’s cavities. EFFICIENT: Use of the Tidal Foam Filter Sponge within your tank or aquarium’s filtration system will help to extend the life of chemical filtration media. The Tidal Foam Filter Sponge is a compatible replacement filter sponge with the Tidal 75 fish tank filters.
