1. Where is the uv germicidal lamp placed in the fish tank uv germicidal lamp is usually placed in front of the filter box in the fish tank. The purpose of this is to let the water flow pass through the germicidal lamp before passing through the filter box. If it is placed in the back, it may affect the nitrification system. uv germicidal lamp is usually turned on all day, which can not only sterilize, but also eliminate algae, protozoa, etc., and has deodorization effect at the same time. However, it should be noted that this kind of lamp has a limited life, and it usually has no effect for about half a year.
2. What are the germicidal lamps in fish tanks1. Built-in germicidal lamps: Built-in germicidal lamps have certain filtering ability, which can clean up bacteria in fish tanks like filters. However, it also needs a certain amount of water flow to play its role. Usually, the flow rate should reach about 500, and the effect is better.
2. Open germicidal lamp: This germicidal lamp is mainly used in the filter brush area, or placed in the water pump area, and the whole filter area can be irradiated when the lamp is turned on. Its irradiation time should be properly controlled. If it is too long, it may lead to the increase of nitrite, which is harmful to the health of fish.
3. Matching germicidal lamp: Matching germicidal lamp is usually used for upper filter fish tank, which can be directly equipped on the water pump interface. In order to keep it clean and sanitary, it should be cleaned regularly.
4. External connected germicidal lamp: This kind of germicidal lamp needs to be connected with water pipes and does not need to be soaked in water. Usually, the water in the pump area should be diverted to the area irradiated by the germicidal lamp, and then led to the front of filtration to complete filtration.
