sea tank and freshwater tank is the first difference between them from their names, that is, the difference between water. Sea tanks use seawater, but because clean natural seawater is not easy to obtain, artificial seawater is generally used, which is made of fresh water and sea salt. Fresh water tanks use fresh water, which is usually not salted, and usually comes from tap water, which can be used after dechlorination.
, the sea tank raises the sea fish, the freshwater tank raises the freshwater fish, this is their second difference. There are not many kinds of marine fish that are suitable for raising in fish tanks. Generally, marine fish of Acanthuridae, Papilionidae, Pomacentridae and Sickle can be domesticated. There are more freshwater fish. Small fish tanks can raise guppies, moonfish, goldfish, and larger tanks can raise koi, arowana, map fish and so on.
. There is another difference between the sea tank and the freshwater tank, that is, the equipment in the tank. Freshwater tanks can be used to raise fish without equipment, or with filters, oxygen pumps, heating rods, etc. Sea tanks need more equipment, such as a protein separator to maintain water quality, as well as lights, pumps, wave machines, heating rods and filtration equipment, so as to provide a suitable living environment.
