The complete Flowranger® Line uses superior Flowranger® filtration media. Most of our competitors use high-density filter pads with limited filtering capabilities. However, to achieve optimum filtration it is necessary to use a progressive density layer system, which deters water channeling and rapid solid congestion. Flowranger® filtration media provides an increased surface area to harbor the growth of beneficial bacteria and the removal of solids.

Progressive densities allow for step-wise transition from mechanical to biological filtration.
Made of thermo-polypropylene compounds, which are non-toxic to the environment.
Excellent surface area per square foot with good adhesion of nitrifying bacteria.
High free volume for smooth, even water flow throughout the filter.
Extremely resistant to clogging and channeling.
Easy cleaning and maintenance.
