MarinePure ROCK Small

Marinepure creates the perfect bio home for bacteria with its porous inert structure and designed to maximise filtration with bio film technology.

Size - as a guide we measured one small rock and it was 13cm X 13cm x 10cm - as the shapes are different on most of the rocks please use this just as guide.


  • Ammonia, Nitrite, and Nitrate Removal
  • The perfect substitute for Live Rock- safe, effective, and economical.
  • Primarily designed to provide deep anaerobic zones for de-nitrification.
  • Great for aquascaping and as a substrate to grow corals.
  • Use directly in Aquarium tank - available in small or medium sizes

  • MarinePure ROCK and water chemistry
  • Because MarinePure Rock is inert and made from a ceramic it does not effect the water chemistry and can be used in many different types of tanks including planted, freshwater and saltwater tanks.

  • MarinePure Rock Natural Appearence
  • Although man made the Marinepure gives a natural look as the shape is based upon a mold of a natural rock which gives a great appearence in both aquascapes and reef tanks.

  • Advantages using MarinePure bio-media instead of live rock?
  • The harvesting of live rock has contributed to the demise of the world’s coral reefs, MarinePure bio media is a manmade product and does not harm the environment.
  • Live Rock is popular because in addition to eliminating ammonia and nitrites it will also reduce nitrates.
  • MarinePure mimics live rock in this arena and is more effective because of the expert engineering involved to increase surface area along with an open pore design.
  • MarinePure allows more space for additional beneficial bacteria to grow increasing the capacity to eliminate ammonia and nitrites and reduce nitrates.
  • MarinePure also addresses some negatives associated with the use of live rock. Live Rock comes complete with live and dead critters that can contaminate a fish tank.
  • Live Rock is heavy and can displace water needed by aquarium inhabitants.
  • MarinePure bio filter media is contaminate free and lighter than live rock.
  • It can be sanitized and reused and is also a great home for welcome guests like Copepods.

  • How much do I need?
  • As an estimate MarinePure Small ROCK is more effective than 4.5kg of live rock. Medium ROCK would compare to over 11kg of live rock.

  • Nitrate Reducing properties.

    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.
