The Difference Between Freshwater and Saltwater

Freshwater is defined as having a low salt concentration — usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e., ocean). There are different types of freshwater regions. Freshwater is found in ponds, lakes, rivers, streams, and wetlands.

Marine environments contain saltwater. Saltwater Marine environments include the ocean, coral reefs and estuaries. Saltwater requires a higher concentration of salt to maintain a suitable salinity for fish. It is important to note that Reef tanks require higher amount of salt and certain fish, corals and critters may not be suitable for the higher levels of salt and vice versa. While regular salt Sodium Chloride (NaCL) with no additives can be beneficial when added to freshwater fishtanks in small amounts it will not work in Saltwater or Reef aquariums. A seasalt mix such as Coralife, Kent, Instant Ocean, or Red Sea will need to be purchased
