Artificial seawater is a valuable resource for maintaining marine animals in an aquarium because it is initially free from pollutants and disease-causing organisms that may be present in natural water sources.1

While natural seawater is an alternative, the use of artificial formulas allows for greater control over the initial purity of the environment. However, it is important to note that artificial seawater may not be as suitable for all types of organisms as natural seawater. In practice, maintaining marine life requires careful management of water quality, including the removal of metabolic wastes and the regulation of acidity, regardless of whether the water is natural or artificial.1
