How long will it take to sterilize the water in the fish pond?
Lime as the main component of calcium oxide, usually method was mainly composed of calcium carbonate rock, calcined at high temperature, then decomposition of carbon dioxide and calcium oxide (chemical formula: CaO, which is also known as lime, marble). Reaction equation for the dissolution of lime in water: CaO+H2O=Ca (OH) 2.
Lime is calcium oxide, is one of the drugs during the disinfection effect, water quality improvement, prevention and treatment of fish diseases most commonly used in aquaculture wide. Practice has proved that the scientific use of raw ash ponds can effectively kill Essien, pathogens (bacteria, parasites) improve sediment permeability, adjusting pH value, enhanced water buffering capacity, promote the growth of phytoplankton, so as to improve the production capacity of fish ponds. However, many key links in the use of quicklime are often neglected, while the use of drugs is greatly reduced, and even adverse consequences. Here are some notes on the use of quicklime in fish ponds for your reference.
At least 1-2 days or soThere is fish in the fish pond and can not be sterilized with lime. When lime is dissolved in water, it will produce strong alkali, strong calcium oxide, and will emit a lot of heat, so the fish will die in large quantities.
