If you want to make the water clear without changing the water in the fish tank, you need to install a filter in the tank. There are many types of filters, such as upper filter, bottom filter, back filter, side filter, filter barrel and so on. According to the specifications of the fish tank, the appropriate filter equipment should be selected. Generally, the upper filter or filter barrel can be used for small fish tanks, while the bottom filter can be used for large fish tanks. Filter materials need to be placed in the filtration equipment, such as filter cotton, activated carbon, bacterial house and so on.
of water quality deterioration? 1. Affect viewing: Water quality deterioration will make the fish tank particularly turbid, thus affecting the viewing effect. This is mainly due to the proliferation of microorganisms in the water, resulting in biological turbidity, and the reason for their production is that the water is too fertile, indicating that the organic matter content in the water is too high due to excessive feeding at ordinary times.
2. Harm to health: If the water is not good, the health of the fish will also be affected. After the deterioration of water quality, the increase of ammonia nitrogen content will lead to the poisoning of fish, which will make them depressed, lack of appetite, color ammonia nitrogen, and even congestion of the body surface.
3, cause dead fish: If do not change water for a long time, besides can affect health, still can make its die. Once this happens, it is very dangerous, because a large number of fish will die. It is impossible to improve the water environment only by changing the water. It is necessary to turn over the tank again, take out all the things in the tank, and then disinfect the water again.
