Copper acetate is generally used as a regulator of excessively high pond water pH in aquaculture. It is generally used when the pH is greater than 9. Note that the principle of use is to use a small number of times, so as not to cause pH shocks and cause stress reactions in the cultured species.
Generally, the pH value of natural surface water is between 6.7-8.5, which can be cultured normally. The pH value of surface water in coastal and saline-alkali areas is higher, and the pH value in mountainous areas is lower. Normally, there is no need to adjust the pH value of water in production. If it is high, it is best to adjust the acid with starch, which is good and cheap, and the dosage is 1-2kg/mu.m.
Disinfection and sterilization are carried out by disinfectants for aquatic products, such as trichloroisocyanuric acid powder, benzalkonium bromide solution, bromochlorohydantoin powder, glutaraldehyde solution, chlorine dioxide, povidone-iodine solution, etc.
EM bacteria is a new type of compound microecological preparation. It is a brown translucent liquid with a pH value of between 3.5 and 4.5. It is compounded by photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, acetobacter, and other microorganisms. It has a variety of functions. In summary, the main ones are: promoting animal growth, improving feed utilization, enhancing the body's disease resistance, removing fecal odor, improving the ecological environment, etc.
