Biological filtration is the number one key to a nice and stable reef tank, and anytime we can sneak in some MarinePure Biomedia into an All in one tank, sump, or even overflows we will.  We have run density tests and they have proved to be more porous than any live rock we could find. They are a great base for sponge growth, microfauna, and even coral frags.

MarinePure is an inert ceramic material with open flow architecture, extremely high surface area and natural wetting properties. A Single 1½” Marine Pure ceramic sphere has 240 square feet of surface area. This means you can fit almost 20 times the surface area in the same space verses bioballs.

The media’s composition is similar to natural rock formations. MarinePure provides approximately 150,000 sq. Ft per cu. Ft (510 m2/L) of accessible surface area. The properties of MarinePure create a stable home for a dense population of beneficial bacteria that remove ammonia and nitrites from your aquarium. Some systems will also see a decrease in nitrates. MarinePure will work in sumps, trickle filters, wet/dry filters, hang on the back filters or directly in the tank.
