The preparation of seawater is generally to dissolve the finished artificial sea salt in fresh water, which is commonly used artificial seawater. Artificial sea salt is mainly composed of several kinds of salt mixed in a certain proportion. Specifically, sodium chloride, magnesium sulfate and potassium chloride are mixed according to the ratio of 3: 2: 1 to make them account for 90% of the total proportion, and the remaining 10% can be replaced by some trace elements. These trace elements are very important to marine fish and other mollusks, especially corals and anemones. Their bright colors cannot be separated from the supplement of trace elements.
Pay attention to three points when configuring seawater:
First, when using artificial seawater, do not use metal containers;
2. After seawater configuration is completed, it is necessary to start circulating filtration, heating and oxygenation (because the newly configured seawater has sediment and looks turbid, it can be clear after turning on circulating filtration 10 hour);
Third, we should pay attention to measuring seawater quality regularly every day. If the water quality is stable after a week, you can go fishing.
The other is the choice of fish species. At present, marine fish ornamental fish are mainly divided into clown fish, schizothorax fish, big fairy fish, small fairy fish, upside-down fish, fox fish, Chinese head fish, sea goldfish, goby fish, lion fish, shellfish, sea eel, bream fish and ornamental fish.
These fish have different living habits, so it is necessary to know their living habits before raising them in order to better cultivate marine fish.
