Poret® Filter Cartridge
Our foam filter cartridges are foam blocks with a vertical hole bored all the way through. They can be used as prefilters, replacement for ATI hydro sponges, to make cubefilters, with a powerhead as internal power filters, etc. Thus, these cartridges are very rugged and have a very long lifespan.
PPI = pores per inch: 25/30 PPI = medium;
