The main role of calcium oxide in aquaculture

1. Qingtang disinfection active lime manufacturer

The amount of calcium oxide in the clear pond can be based on the depth of the water, the depth of the silt, and the level of calcium oxide content, and the level of activity. When calcium oxide is used from 60 to 300 kg, the pH of the pool water can be quickly increased to above 11 in a short time, so as to achieve The purpose of clearing the pond is to have a strong killing effect on most reproductive pathogens, and a strong destructive effect on many bacteria, insects and even viruses.

2, improved bottom mud

Calcium oxide precipitates calcium carbonate when it meets with water. Calcium carbonate can loosen the bottom mud and increase the aeration conditions of the bottom mud, thereby promoting the activities of various microorganisms in the bottom mud, and speeding up the decomposition and mineralization of organic matter in the bottom mud.

3, adjust the water to change the bottom

When carrying out high-content calcium oxide light-dosage (5-20 kg) water disinfection on fish ponds, calcium oxide can neutralize the water quality, adjust the pH value of the pool, increase the alkalinity and hardness of the water, kill bacteria, and promote The anaerobic flora at the bottom of the pool mineralizes organic matter and decomposes humus, which precipitates the suspended colloidal particles in the water and improves the transparency of the pool water; it can improve the bottom quality, increase calcium fertilizer, and increase the utilization rate of calcium and phosphorus by aquatic (phytoplankton) plants , Which is conducive to the reproduction of plankton and maintains a good ecological environment in the water body.

4, increase fertility

After applying calcium oxide, the concentration of calcium ions in the pond increases, which can exchange various salts adsorbed in the sludge and re-dissolve them into the pond water, increasing the fertility of the pond water, which is conducive to the growth and reproduction of fish feed organisms.

5. Prevention and treatment of fish diseases

Through the practice of farmers, the use of calcium oxide has a good therapeutic effect when the fish disease occurs and cannot be cured for a long time. The analysis may be due to the long-term disease. If it is destroyed, calcium oxide has the effect of neutralizing water quality and can restore the water ecosystem. Calcium oxide has the function of killing insects, sterilizing and algae, so it is effective.

6, detoxify

After using calcium oxide, the calcium ions produced can eliminate or reduce the toxicity of excessive potassium, sodium, zinc, manganese, iron, lead and other metal ions in the pool water.
