Silica Sand 25 kg
This specially graded marine sand is guaranteed to contain a high percentage of algal oolites. The algal oolites are highly porous and provide a perfect habitat for de-nitrifying bacteria. Due to their uniquely porous nature, oolites can house several hundred times more bacteria than crushed shell or calcium based rocks i.e dolomite gravel.

In simple terms, the Silica Sand will mature very quickly and remain relatively stable. Silica Sand should be lightly rinsed in fresh water before being introduced to the aquarium. Suitable for freshwater and marine aquariums.
This Silica Sand is carefully graded to obtain a uniform grain size and colour. It has a highly porous structure which makes it an ideal biological filter medium, especially when used in conjunction with mechanical filtration. It should be noted the Silica Sand has equal buffering capacities to calcium or Dolomite gravel, but its larger surface area makes it the ideal choice where a buffering and biological substrate is required.
