The function of the filter device in the fish tank is to remove feces and other dirt in the water, keep the water clean and oxygen sufficient, and provide a clean environment for the fish. If the tank where guppies are kept is small, the water will be polluted faster, and the use of filters can slow down the pollution rate. In this way, even if the water is not changed so frequently, the fish can live normally. If there is no filter device installed in this case, once the water quality is muddy, and the owner forgets to change the water, the fish is very easy to get sick. However, if the size of the tank is very large, the water quality will not deteriorate so quickly. As long as the water is changed regularly, the water quality can be kept clean. In this case, it is not necessary to install a filtering device.
The size of guppies is small, so you can't choose a filter device with too large filter holes. And it does not like to live in the environment with too much water flow, so it is better to choose small and medium-sized filtration devices. Like waterfall filtration, water goblins, plug-in micro-filter cartridges are all possible. Among them, the water goblin is the use of more filters. It does not cause too much water flow, is easy to clean, and can achieve the water purification effect needed by guppies. In addition, water goblins can also provide a place for the survival of nitrifying bacteria. Nitrifying bacteria can also properly clean water and provide oxygen, which is very important for guppies. Therefore, it is suggested that the water goblin should be selected as the filter device for raising guppies.
