The water of marine fish needs to be mixed with fresh water and sea salt. Among them, fresh water can be exposed to the sun, tap water can also be used with pure water, sea salt multi-use imported brands. Then add sea salt to fresh water, usually a liter of water needs 30-35 grams of sea salt, after adding gently stirring, but also aerating oxygen, wait until 1-2 hours after the match.
1. Lighting equipment: It is necessary to have lighting when raising seawater fish. Lighting can not only make aquatic plants grow better, but also make the color of fish more bright. Common lighting equipment includes fluorescent lamp, mercury lamp, coral and metal halogen lamp, among which coral is suitable for feeding invertebrates, which is divided into blue lamp and fiber lamp.
2. Insulation equipment: Seawater fish have higher requirements for water temperature, so good insulation equipment is required. Small aquariums can be equipped with electric heating tubes, power from 100W to 300W, fixed at both ends of the aquarium. When the water temperature is close to 30 C, it is necessary to cool down, which can be put into refrigerant or plastic bags with ice cubes.
3. Protein separator: The protein separator has a good purification effect on the water quality of seawater, and can remove organic particles, proteins, harmful metal ions, etc. Therefore, it is also essential for raising seawater fish. It can concentrate the bubbles in water and then discharge them, so as to achieve the purpose of purifying water quality.
4. Carbon dioxide supplementary equipment: When the pH of seawater drops to 8.0, it is necessary to use carbon dioxide supplementary equipment to supplement carbon dioxide, so as to maintain the stability of seawater quality, especially the stability of calcium ions and hardness.
