Live Sand (“LS”) is essentially a combination of non-living substrate with a myriad of tiny beneficial life forms that grows on it. It is home to many microscopic biological bacteria. LS can form as a main base for biological filtration in a marine aquarium, while the living organisms in the sand bed can help consume the organic matters.
LS can be collected live from the ocean, or can be cultured from a non-living oral sand to make it live. The quickest method in starting a marine aquarium is to use 100% LS which are commercially sold in bags. Using this method, there is no waiting period or delay in the biological cycling process for the beneficial bacterial to establish themselves to effectively and biochemically cycle your aquarium that will provide a healthy environment.
Some popular choices of many expert aquarists for LS are Caribsea or Nature’s Ocean. Both provides sand from the ocean with biofilm of bacterial in their natural state that immediately removes toxic waste from the water in every new tank.
