Details

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, an aquarium will mature very quickly and remain relatively stable. Tropical Marine Sand can be used with a standard undergravel filter or power filter. When using undergravel filtration, there should be between 21/2 - 31/2 inches all-round coverage, which equals approximately two bags per square foot of aquarium base. Tropical Marine Sand should be lightly rinsed in fresh water before being introduced to the aquarium. Suitable for freshwater and marine aquariums.
