Home care for giant clams

The key to success in caring for giant clams relies on the ability of the hobbyist to replicate the conditions of the animal's natural environment. Figure 1 illustrates the giant clam's home range. The hobbyist must attempt to reproduce water conditions that exist in these regions. The paper attempts to outline proper illumination and techniques used to achieve several water parameters important to maintaining giant clams in a closed system such as salinity, pH, calcium, and organic waste concentration.

While it raises topic strings, it can be improveed

  to break up single, long list of topics.

Revision. The hobbyist best cares for giant clams by replicating their natural environment. Figure 1 shows that giant clams inhabit the tropical waters of the Eastern Hemisphere. Besides closely regulating the obvious parameters of temperature, salinity and pH, the hobbyist must also supply calcium for the clams' shell growth and survival. In a closed system, organic waste concentration must be removed. Most surprising is the need for illumination to maintain an algae that provide essential nutrients to the giant clam.
