Two roles of Calcium Oxide CaO in aquaculture
Calcium Oxide CaO is quicklime, which can be used as fillers, building materials, refractory materials, etc., but the role of Calcium Oxide CaO is not only these, Calcium Oxide CaO is also widely used due to its strong alkalinity, disinfection, sterilization, insect control and other advantages. It is used in aquaculture and has played a great role, so it is called "the treasure of fishermen" by fishermen and farmers.
1. Qingtang disinfection
The dosage of Calcium Oxide CaO for clearing ponds can be based on water depth, silt depth, and Calcium Oxide CaO content and activity level. When Calcium Oxide CaO is used from 60 to 300 catties, the pH value of pond water can be rapidly increased to above 11 in a short time. , so as to achieve the purpose of clearing the pond, and at the same time, it has a strong killing effect on most reproductive pathogens, and also has a strong destructive lethality on many bacteria, insects and even viruses.
2. Improve the sediment
Calcium Oxide CaO produces calcium carbonate precipitation upon contact with water. Calcium carbonate can loosen the sediment and increase the ventilation conditions of the sediment, thereby promoting the activities of various microorganisms in the sediment and accelerating the decomposition and mineralization of organic matter in the sediment.
