MarinePure is hands down the BEST biological filter media on the market, and with their long lifespan, are definitely worth the pricetag. Their immense surface area to volume ratio is what makes this product so desirable.
MarinePure's bio-media is the most technically advanced bio-media available today because it features Thin Bio-Film Technology™
Bio-Film Technology is the combination of vast surface area and open/interconnected pores allowing a thin bio-film to develop. This thin film allows bacteria to flourish because necessary nutrients are immediately available. With the open pores, old dead bio-film is easily flushed from the media and will not plug the media. Water flows through the media, not around as with other denser media, thus utilizing the most surface area for beneficial bacterial growth.
