Cérock 25

ReefX® Cérock is a highly porous foamed ceramic synthetic live rock media.

It is lightweight, strong and inert with an extremely high surface area that makes it an excellent choice for colonisation by microorganisms in biological filtration in marine, reef and freshwater aquariums.  It behaves in the same way as natural live rock but is completely sustainable and free of any undesirable organisms.

Made from specially selected clays and raw materials that are rapidly sintered at high temperature to produce a foamed ceramic live rock substitute.  Cérock is pH neutral and free of phosphates.  The massive surface area of 90m2 per litre of material is around 40 times the area of many other foamed ceramic products and provides the highest area possible for beneficial bacterial to colonise and remove waste from the water.

Add anywhere in an aquarium

Rinse before use.  You can use as little or as much as you need, in high and low flow areas.  Cérock is the perfect media for sand-dwelling fish that construct burrows, and for creating raised areas for clams and corals.
