In the process of raising fish, there may be a fishy smell in the water, and even the water that has just been changed may have a fishy smell. Specifically, there are the following reasons:
1. The fish tank is not cleaned up: We may only change one third or one quarter of the water every time we change the water. In this case, if the feces and food residues in the fish tank are not cleaned up, the water will still emit a fishy smell after changing the water.
2. There is no filtration system in the fish tank: Furthermore, it may be because there is no filtration system in the fish tank, or the function of the filtration system is not good. In this case, the newly changed water is also easily contaminated by fish excrement, and then it will emit a fishy smell.
3. Fish are sick: It is also possible that fish are sick. In this case, even if the water is changed, it is easy to emit fishy smell because the disease of fish has not been cured.
After the fishy smell appears in the fish tank, some substances can be used to reduce or eliminate the fishy taste in the fish tank. Salts are a common substance we use. After changing the water, you can sprinkle a little salt, but not too much, the concentration of salts in the water can not be too high. At the same time, it can also make the fish tank receive light for a period of time every day. In addition to salts, there are some substances that can be used, which also have the effect of removing fishy smell, such as vinegar. There are also some specialized substances, such as chlorine dioxide effervescent tablets and so on, which can be tried.
