in time. If the fish tank is smelly, the first thing to do is to change the water in time. Usually, it should be changed once a week. Each time, the water should be changed by about a quarter. If the water is changed less, it will not work, but if it is changed too much, it will also stimulate the fish. It should be noted that the temperature before and after the water change should be consistent.
is that the ammonia nitrogen content is too high, and ammonia nitrogen is produced by the decomposition of organic matter. Organic matter is generally the fish food we feed and the feces discharged by fish after digestion. By reducing the feeding amount, we can control the content of residual bait and feces, so as to avoid the stink of the water body.
cultivation. The cause of odor mentioned above is ammonia nitrogen, and there is another way to solve ammonia nitrogen, that is, to establish a nitrification system. The nitrification system is made up of nitrifying bacteria that can convert ammonia nitrogen into nitrates, so that the water does not stink, and nitrates can be absorbed as nutrients for aquatic plants.
plants can improve water quality and release oxygen through photosynthesis. The increase of oxygen content can avoid the reproduction of anaerobic bacteria, thus avoiding the odor of water. It should be noted that aquatic plants must choose the appropriate species, which usually depends on the situation in the cylinder and the degree of light exposure.
