The natural seawater is full of elements and can be used for a long time. It can be used for two years under stable water quality. Natural seawater can provide the best ecological environment, so that ornamental fish can show brighter body color. The disadvantage of natural seawater is that it is not easy to collect, there are many bacteria in the water, it must be filtered and sterilized, and the storage time is long before use.

Artificial sea salt is convenient to use, sterile, free of impurities, no pollutants, and easy to prepare. Sea water can be prepared at any time. When the elements are insufficient, they can be added and replaced at any time. It is very convenient to store and transport, and it is generally popular among marine fish lovers. The serial sea islands of Hawaii and Taiwan also use artificial seawater to raise seawater ornamental fish. Artificial sea salt is a very important necessary product for fish farming for people who raise sea fish. Pay attention when using artificial sea salt, and do not mix products from different factories.
