Destructive algae grow much faster than SPS corals and can quickly cover the corals, shading them from light and damaging the coral's sensitive skin. Despite their faster growth rates, algae do not over take SPS corals in the wild. This is because of the presence of numerous herbivorous animals which readily eat vulnerable algae. In order to maintain this ecological balance in the aquarium, reef janitors, hermit crabs and snails, must used. These animals will eat algae and clear sediment off the SPS corals. They are available for sale from GARF.

With all this knowledge, you may be asking yourself, "is my aquarium ready for SPS corals?" An aquarium is usually ready after six to eight months for the first hardy species of SPS corals. The best way to tell whether or not your aquarium has sufficient water quality is by observing the growth of coralline algae. Coralline algae is a beneficial algae that forms a calcium carbonate matrix. It is usually purple, with a bumpy surface and looks like a thin coating of plaster, though it is much harder.
