Seawater ornamental fish aquarium: The size of seawater fish aquarium is larger than that of freshwater aquarium, its water capacity is more, and the height of the aquarium is also higher.

It is difficult for seawater aquarium fish to live in freshwater, and it is also difficult for freshwater aquarium fish to live in seawater. Therefore, the prerequisite for the breeding of seawater aquarium tropic fish is to fully understand the characteristics of seawater.

To raise marine ornamental fish, you must first think about how big a sea aquarium tank you need. Secondly, relevant equipment should be prepared, such as protein skimmer, salinity meter, and reef sea salt. Of course, if you don't keep corals, you can choose relatively cheap LED lights.

The hardness of water is the concentration of "multivalent metals" dissolved in water.

Salinity is extremely important for marine ornamental fish.

The so-called salinity is the weight percentage of all inorganic salts present in 1 kg of water.

The usual way to add oxygen to the seawater in the aquarium is to use a special oxygen pump.

Dissolved oxygen is one of the important conditions for the survival of aquatic organisms in the ocean.

Changes in temperature will cause a series of changes in all environmental factors, which directly affect the survival of aquatic organisms.

This is the biggest difference between artificial seawater and natural seawater in the ocean.

It is best to deploy the artificial sea 24-48 hours before use.

The natural seawater is full of elements and can be used for a long time.
