Aquarium Sea Salt
All marine organisms have evolved in, and are adapted to, the natural marine environment as found in the sea; more particularly in the coral reef. Although the salinity of natural seawater varies geographically, natural seawater contains over 70 chemical elements in a ratio that is remarkably constant all over the world. The aim of every marine aquarist is to create and maintain an artificial environment that replicates the natural environment as closely as possible. Correct filtration, suitable lighting, balanced stocking and appropriate feeding are essential factors, however the basis of any successful aquarium is the water itself and maintenance of its delicate chemical balance. Many of the chemical elements present in seawater are constantly being depleted as they are utilized by the animals or removed by filtration and should be replenished regularly. Even with a well-balanced aquarium ecosystem, there may still be gradual buildup of undesirable elements in the seawater that are not removed by filtration. It is therefore good practice to dilute these undesirable elements by regular partial water changes.
