BIO FILTER MEDIA GEMS 90 G

The MarinePure GEM is about 3/4" diameter part that will be the perfect biological media for canister filters, hang on the back and nano-tank systems up to 70 gallons. The GEMs have the same porosity as our popular MarinePure SPHERES. Their unique combination open flow porosity and high surface area means one box of these little beauties is packed with over 1,450 Square Feet (135 Square Meters) of accessible Surface Area. They will be the perfect solution for ammonia and nitrite elimination, and most users will also see better control in Nitrates. Why Use MarinePure? • Better value due to high performance • Reduced tank maintenance • Allows for higher fish loads • Can use a smaller filtration footprint • More consistent water chemistry • Easy to shape Can be used in a variety of applications; • Used in tank • Used in sumps • Used in canister filters • Used in DIY filters • Used in trickle or shower filters • Used in waterfall filters • Used in hang on back filters Thin Bio-Film Technology Combination of vast surface area and open/interconnected pores allow 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 medias, thus utilizing the most surface area for beneficial bacterial growth.
