Ultraviolet sterilizer is a common disinfection method. Usually, a water tank or water pipe is connected in front of the ultraviolet radiator, which can effectively inhibit and kill germs and harmful microorganisms in the fish tank water after ultraviolet irradiation.
When using ultraviolet sterilizer to disinfect fish tank water, the following points should be paid attention to:
① The power of ultraviolet disinfection lamp should be more than three times of the water capacity of fish tank, and the lamp should be replaced regularly. Don't use expired lamps.
② The ultraviolet sterilizer should be self-cleaned before use, so as to avoid reducing the disinfection effect due to ultraviolet lamp pollution.
(3) The ultraviolet sterilizer cannot eliminate ammonia nitrogen, nitrogen and other substances in water. If these substances need to be eliminated, additional treatment is needed.
2, the use of hydrogen peroxide disinfection
Hydrogen peroxide is a relatively safe, non-toxic and residue-free disinfectant, which can effectively kill bacteria and aquatic animal pathogens in fish tank water.
When using hydrogen peroxide to disinfect fish tank water, the following points should be noted:
① Hydrogen peroxide needs to be diluted with diluent before use, and it is best to use pure water when preparing diluent.
(2) During the operation, it is necessary to fully stir to make the hydrogen peroxide fully contact with the water and harmful microorganisms in the fish tank.
(3) After using hydrogen peroxide, it needs to be thoroughly cleaned to avoid affecting aquatic animals.
3, using sodium chloride disinfection
Sodium chloride is also a common disinfectant. Disinfecting fish tank water with sodium chloride can remove bacteria and microorganisms in the water, and also can eliminate some water quality problems.
When using sodium chloride to disinfect fish tank water, the following points should be noted:
① Pretreatment is needed before disinfection to make the PH value of fish tank water between 7.0 and 8.5, which can enhance the disinfection effect of sodium chloride.
② When using sodium chloride to disinfect fish tank water, control the concentration. Generally speaking, 10 ml sodium chloride can be added with 4L water.
(3) After disinfection with sodium chloride, it needs to be thoroughly cleaned to avoid affecting aquatic animals.
4, using ultraviolet and chlorine combined disinfection.
Combined disinfection with ultraviolet and chlorine is a comprehensive disinfection method, which can kill most water quality problems, as well as bacteria and harmful microorganisms in fish tank water.
When using ultraviolet and chlorine to disinfect fish tank water, we should pay attention to the following points:
① Pretreatment is needed before disinfection to make the PH value of fish tank water between 7.0 and 8.5, which can enhance the disinfection effect of chlorine.
(2) When chlorine is used to disinfect fish tank water, the concentration should be controlled to avoid harm to aquatic animals.
(3) During the operation, sufficient stirring and contact are needed to avoid local non-sterilization.
To sum up, the disinfection of fish tank water is one of the important measures to ensure the health of aquatic animals. By choosing appropriate disinfection methods, harmful substances and bacteria in water can be completely removed, providing a good environment for the ecology of fish tanks.
