When raising koi, water quality is a very important factor, and it is necessary to keep the water quality suitable all the time. However, sometimes it is inevitable that the water quality will be turbid. At this point, we must first find out what causes it, and then take appropriate measures according to this reason. Specifically, there are mainly the following three reasons:
1. Biological reasons: here refers to the water pollution in the fish tank is caused by some microorganisms, or by the mass propagation of some green plants. For this reason, it is best to use ultraviolet germicidal lamps and other tools to deal with.
2. Chemical reasons: This refers to the fact that the water pollution in the fish tank is caused by the addition of certain drugs. For example, when the koi was sick, some drugs were put into the fish tank, but they did not pay attention to cleaning up later, which led to pollution. For this reason, it is preferable to purify the water by adsorption with activated carbon.
3. Physical reason: This refers to the fact that there are some particulate matter in the fish tank that causes the water to be turbid. For example, when feeding, too much food is put in, the fish are not eaten up, and the breeder does not clean them up in time, thus causing pollution. In this case, cleaning can be performed by using a tool such as a filter.
If the water in the fish tank is turbid, nitrifying bacteria can be put to purify it. In order to keep the water quality in good condition, the filtration and circulation system in the fish tank is indispensable. In this system, nitrifying bacteria can be placed, and the effect is better.
