MarinePure Spheres Bio Filter Media

MarinePure Spheres promote the colonisation of denitrifying bacteria within their tiny pores, and within a span of a few short weeks, each sphere becomes a powerful bio filter that naturally removes ammonia and nitrite from the water, while minimizing dissolved nitrates.

As water flows freely through the MarinePure Spheres, the denitrifying bacteria in the pores continually break down and remove the nitrogeneous wastes, thus keeping the aquarium water safe for fish and corals.

MarinePure Spheres makes an excellent substrate for microfauna, coral, and sponge growth.

MarinePure Spheres also provides an excellent habitat for copepods to live, hide, and reproduce.

You can place MarinePure Spheres anywhere in the tank, but it is best used in refugiums, sumps, all-in-one filtration chambers, wet/dry filters, trickle filters, canister filters, and HOB filters.

MarinePure Spheres is made of inert material, safe for fresh and marine tanks, including reef aquarium.


  • MarinePure Spheres is designed to remove ammonia and nitrite while minimizing nitrates in the aquarium.
  • MarinePure Spheres delivers superior efficient bio-filtration, thanks to its massive porosity and surface area that enhances the growth of denitrifying bacteria inside them.
  • With up to 80%+ open porosity, MarinePure Spheres promotes excellent water circulation, and is much less likely to clog than other bio filter media.
  • MarinePure Spheres is made of inert ceramic, safe for all aquarium including reef.
  • MarinePure Spheres is made of Aragonite (carbonate mineral) composition, similar to natural reef rock, naturally buffers pH and stabilises water chemistry.
  • MarinePure Spheres allows your aquarium to support a larger bioload and reduces your tank maintenance workload.
  • MarinePure Spheres can be washed, sterilised, and reused.
