Is There A Reason To Use Aquarium Salt?

In nature, there are three categories of fish: freshwater, brackish or saltwater. Each has evolved to develop in its respective natural habitat. When you recreate a habitat in the aquarium, it is important to generate water conditions that are as close as possible to the natural conditions that exist in nature.

According to the type of habitat that you want to create, you may require the addition of salt.  Go here to view some examples of salt. There are two types of salt for use in an aquarium:

-Aquarium salt (for fresh water)
-Sea salt (for salt or brackish water tanks)

pile of saltSalt for aquariums is essentially just sodium chloride, also known as common salt, table salt and rock salt. It does not contain trace minerals or trace elements.

The sea salt type contains micro minerals and trace elements, in addition, it has the capacity of buffering which helps to maintain the pH in a high range. The exact amount of micro minerals / trace elements varies from manufacturer to manufacturer.


Sea salt is indispensable for salt or brackish water tanks because these salts are formulated specifically to help recreate the water conditions that can be found in nature. When you look for sea salt online, buy one that is as similar to salt water as possible and contains, or contains few, Impurities in it.

The salt does not dissolve easily. As the water evaporates from the aquarium, the salt remains. Therefore, when filling the aquarium, you should only add ionized water or fresh distilled water. Brackish water is basically dilute sea water.


In nature, most freshwater fish live in habitats where the level of minerals can not be estimated.

Nevertheless, All agree that the use of salt has advantages in the conservation of certain species of fish or in the treatment of some diseases. Use salt for aquariums only when you need to and it is appropriate.
