The biological diversity found on live rock is a microcosm of the natural reef environment. It is this diversity that helps replicate, in the home aquarium, the efficient use of nutrients found in nature. The balance struck between the import and export of nutrients provides effective control of aggressive growth of opportunistic organisms. All live rock inhabitants are important parts of the reef ecosystem (neither good nor bad) but some species become problematic when conditions in your reef system are out of balance.
Live rock bursts with a variety of life forms ranging from microscopic plants and animals to larger algae and invertebrates including coralline algae, sponges, feather duster worms, macroalgae, microcrustaceans, and countless others. This diversity of life and its rugged, unpolished beauty make live rock a prized addition to any marine aquarium.
Under proper conditions, this plethora of organisms flourish and each organism performs a different function and contributes to the overall health of the entire system. Live rock, rich with life, provides many benefits. For example, coralline algae and macro algae are very useful in controlling the growth of unsightly nuisance algae by actively competing for space and nutrients. Macro algae also provide food and shelter for other species and offer a visually appealing presence in the aquarium. Sponges and feather dusters, besides being beautiful inhabitants, filter out particles and organic materials to keep your aquarium clearer and cleaner.
