Skillful first aid fish pond
1. Introduce fresh, oxygen-rich water into the pond regularly. Ensure the water inlet is covered with gravel or dry wood so that the incoming water flows slowly and prevents disturbing the muddy bottom. At the opposite end of the pond, drain some of the old water to maintain a healthy balance. When adding water, it's best to install a sprinkler on the outlet pipe, allowing the water to fall gently like rain, reducing turbulence. For small ponds, an air pump connected to a hose can be used. Attach a diffuser or poke small holes in the hose to create fine bubbles, increasing the surface area between air and water, thus boosting dissolved oxygen levels.
2. Circulate the water to improve oxygenation. If the pond has stagnant water, use a pump to draw out low-oxygen water from the bottom and let it sit in the air for a while before returning it to the pond. This process helps increase the overall dissolved oxygen content, improving the living conditions for aquatic life.
3. Use two fish ponds to enhance aeration. Pump water from Pond A to Pond B through a small gap. When the water level in Pond B rises above that of Pond A, it will naturally flow back. This system continuously circulates water between the two ponds, enhancing oxygen levels in both, and is easy to manage with good results.
4. If you notice fish floating belly-up, gather them near the inlet and try to save as many as possible. Remove dead fish immediately to prevent water pollution and reduce disease risk.
5. Apply oxygenating agents such as "991" compound oxygen. The dosage is 0.01 kg per kilogram of fish in the pond. For ponds with high organic load, adjust the dose accordingly. In cases of severe fish floating, apply the oxygen agent at the center of the affected area, creating a localized oxygen-rich zone. Use 50-100 mg/m³ as needed. Avoid agitating the water after application to keep it still and allow the oxygen to dissolve effectively.
