Why does BRS recommend this?

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 MP2C-C has an overall surface area of 96,000 sq ft per media bag. The increased amount of surface area will give bacteria a place to colonize helping with the overall biological filtration capacity of your tank.

Random sizes and shapes of MarinePure in an easy to use media bag that has been specifically designed to help with the overall reduction of ammonia and nitrite in the aquarium.

  • Great for tanks from 40 gallons to 1500 gallons
  • Contains 1 Gallon of MarinePure Media (approx.)


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.

Is it best to leave it in the media bag that it comes in when using it in a sump?
Question by: Allen Binder on May 9, 2016, 3:25 PM
Great question. It is personal choice. We recommend leaving it in if you will ever rinse or remove the media. Feel free to let us know if you have any further questions!
