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.
