    I think that we should clean up all kinds of residues regularly, change the water regularly, and never think that you can not change the water if you install a filter. Although filtration can maintain water quality for a long time, the filtration system may also be weakened, or the filtration system itself is not strong enough, in this case, filtration only slows down the rate of deterioration of the water body, and the water body will eventually deteriorate. Therefore, even if there is filtration, it is necessary to change the water regularly to prevent stinky and moldy.

    Is it because there is too much fish excrement, which causes the fish tank to smell moldy, or maybe it is because some fish are dying of lack of oxygen? In normal times, you must pay attention to changing the water in the fish tank and observe the fish more.

    Vacate the fish tank, soak and clean it with sterilizing disinfectant, generally with white vinegar, disinfectant alcohol, potassium permanganate solution, sterilizing water, yellow powder, etc., which can not only sterilize, but also remove the taste.

    So first of all, I think why the water in the fish tank has a musty smell, then there must be dead fish, dead water weeds, etc., and fail to fish out a large number of bacteria in time, resulting in a foul smell in the water. Second, the excrement of the fish is too much, the filtration system, the coagulant nitrifying bacteria are insufficient, and they cannot be decomposed in time. If there is a bottom sand, it may be graded.

    Fish food. So first of all, I think there are some measures taken here, which is to clean or replace some of the filter media, such as changing the mirror to the white mirror and activated carbon to suction out the crisis magazine.

    Many people who raise fish are very motivated at the beginning, they are tired after a long time, they do not have the enthusiasm before, and they slowly do not care about the kindness of the light, especially in the humid place, if they are not cleaned, a large number of mold will be produced, resulting in dust in the dry place of the guard, dust, and water falling into the fish tank, resulting in tastelessness. Therefore, it is necessary to clean the fish tank frequently.

    Heterogeneous bacteria, leftover bait, and feces are all organic matter, and too much organic matter will affect water quality.

    In particular, the biggest harm caused by the proliferation of heterogeneous bacteria is the limited resources in the competition tank, which consumes a large amount of oxygen, encroaches on biological filter media, and acidifies the dwelling, which has a great impact on the water quality of the fish tank.

    If the water quality is not good, of course, there will be a peculiar smell.

    Cleaning the fish tank regularly, changing the water appropriately, and strengthening the filtration effect are the kings.

    1. Use tap water that has been dried in the sun for 3-5 days, speed up the frequency of water change, at least once a day, and change the water in at least 1 2 fish tanks for 3 consecutive weeks.

    2. Increase activated carbon in the filter.

    (activated carbon has the effect of removing color and deodorizing).

    3. Water mildew.

    One of the more specific drugs is potassium permanganate.

    Malachite green, choose which drug depends on your choice, two drugs for the sick fish to carry out a medicinal bath, the dosage is mastered in the water color slightly pink (potassium permanganate), green (malachite green), the dosage is used from less to more, and observe the state of the fish, such as rapid swimming or other uncomfortable symptoms should be immediately fished out, soaking time 10-20 minutes, 3-5 days in a row.

    4. Remember that the dosage of the drug is strictly controlled, too much will cause goldfish poisoning to death, although these two drugs are effective but poisonous, they are the "fierce drugs" in the first drug, and it is best to use an oxygen pump to burst oxygen during the medicinal bath.

    There may be the following reasons for the fishy smell in the fish tank:

    1. The water quality problem of the fish tank, which is also the most common cause of the smell of the fish tank. Fish excretion, leftover food scraps, and algae wilting can all lead to increased water pollution and odors.

    2. The sensitivity of fish eggs has the taste of grandchildren. Bridge-chain fish eggs also have a fishy smell, especially dead eggs, which can quickly decay and give off a disgusting fishy smell if left untreated.

    3. If the ornamental fish is injured, it will also cause the fish tank to stink. When an ornamental fish has a wound, if it is not reduced in time**, it will quickly become inflamed until it decays, resulting in a fishy smell.

    4. The growth environment of ornamental fish is not good, which will also cause the fish tank to stink. When the oxygen content of the water body is insufficient, the fish will become anorexic when they are in this hypoxic environment for a long time, accelerating the production of food residues, and the lack of oxygen will also lead to the death of algae, causing the fish tank to become smelly.

    5. Mold breeds inside the fish tank and emits peculiar smells, resulting in fishy odors in the fish tank. The nutrients, nitrogen, phosphorus and organic carbon inside the fish tank are excessive, and these excess nutrients exceed the self-purification capacity of the water body and the filtration system, and also create a comfortable environment for the growth of algae, which breeds in large quantities and produces a fishy odor.

    Solution: 1. Temporarily transfer the fish to other fish tanks or containers, and vacate the fish tank.

    2. Then soak the dirty fish tank with disinfectant and disinfectant, generally with white vinegar, edible or disinfectant alcohol, potassium permanganate solution, bleaching powder, 84 disinfectant, etc., which can not only sterilize, but also remove the taste.

    3. Note that after soaking the disinfectant, the disinfectant must be fully rinsed off with water.

    4. After cleaning, put the fish tank in the scorching sun for a few days, and finally put the fish back into the fish tank.

    1. Be sure to rinse with clean water after soaking, and the bottom sand, landscape stone and other decorations in the sink also need to be cleaned. If you treat it in this way, the frequency of mold will be reduced, and the fishy smell will be reduced.

    2. Clean up all kinds of residues regularly and change the water regularly. Please do not think that it is okay to filter without changing the water. Filtration can maintain water quality for a relatively long time, and the filtration system will also weaken, and the filtration system itself may not be perfect.

    In this case, filtration will only slow down the rate of deterioration of the water body, and the water body will eventually deteriorate.

    3. If the sink is moldy, it is best to turn the tank in order to prevent the fish from being harmed. Normal fish tanks generally do not become moldy. Because there are fish living in the tank every day and feeding every day, the water will deteriorate and mold will appear.
