Because maintaining a saltwater aquarium is considerably more difficult than maintaining a freshwater aquarium, many experts recommend that novice aquarium owners stay out of the saltwater arena. The problems with saltwater aquarium are related to the extremely stable conditions of the natural ocean environment.

Conditions in bodies of freshwater can vary dramatically from day to day and from season to season. This requires high levels of durability and resilience in freshwater fish species.

Conversely, temperatures and water chemistry in ocean environments remain quite stable over time. This means that saltwater aquariums must operate quite precisely in order to keep the fish within them alive and well.

As just one example, freshwater fish have developed a resistance to acidic/alkaline water conditions that allow them to thrive under conditions that range from 5pH to 9pH, while saltwater fish can only live in water of between 7.8pH to 8.4 pH. Saltwater aquarium owners must also pay close attention to levels of salinity and chloride.
