1, raw materials of sodium chloride 24.72g, potassium chloride 0.67g, calcium chloride 1 .36g, magnesium chloride 4.66g, magnesium sulfate 6.29g, sodium bicarbonate 0.18g, and distilled water to1l are all ready. Dissolve various salts in a small amount of distilled water, then add sodium bicarbonate, and finally dilute with distilled water to 1000 ml.
2. Sodium chloride 45.0g, magnesium sulfate 0. 1 g, magnesium chloride 5.0g, ferric chloride (1%solution)1drop. Firstly, magnesium sulfate, potassium monophosphate and ferric chloride are dissolved in a small amount of distilled water, and distilled water is added to 980ml. Subsequently, calcium nitrate was dissolved in 20 ml distilled water, and this solution was added to the above solution drop by drop, and bottled for storage.

Precautions:
The purpose of sea crystal is to make artificial seawater, which is used for the temporary maintenance of various live seafood products, the reproduction of migratory freshwater products and artificial sea bathing. Using this product is far more convenient and economical than hauling natural seawater.
1, high-purity sea crystals should not be directly added to the existing fresh water solution. It is most suitable to dissolve with clear water first, and then add clear water products after one and a half hours.
2. If the product has caking and deliquescence, its performance will not be affected.
3. The usage ratio is similar to that of natural seawater, and it is measured by 100 kg of fresh water. For example, crabs and groupers need 3.1kg, temporary lobsters need 3．4kg, and seafood such as bamboo and shrimp need 2．8kg. The seawater concentration should be adjusted appropriately according to needs.
4. Generally speaking, it takes 24-36 hours to replace the temporarily cultured seafood. If the breeding density is high, the water change time can be adjusted appropriately.
5. Artificial seawater used for breeding migratory freshwater products shall be allocated and used according to the requirements of breeding technology.
