In the process of raising fish, the water in the fish tank may turn yellow. At this time, it is necessary to understand the cause first. Specifically, the following situations are common:
1. Brown algae outbreak: If the phenomenon of water yellowing is very obvious, even the inner wall of the fish tank has turned yellow, then it may be caused by brown algae outbreak.
2. Caused by sunken wood: Some culturists will put some sunken wood into the fish tank as ornaments in the process of fish culture, but these ornaments may cause the water to turn yellow.
3. No water change for a long time: In the process of fish farming, regular water change is an important step. If the water is not changed for a long time, the water will be full of old water, and the water will turn yellow.
4. Drugs: When fish get sick, you need to use some drugs, which may cause the water to turn yellow, such as yellow powder, nitrofurazone, and so on. In addition, it may be caused by part of the feed.
After the water in the fish tank turns yellow, certain measures need to be taken to deal with it. After understanding the specific causes, you need to prescribe the right medicine:
1. Scavenger algae removal: If the brown algae outbreak causes the water in the fish tank to turn yellow, then you can put a scavenger in the fish tank to remove these algae. If the inner wall of the fish tank is yellow, you need to clean the fish tank and replace the water.
2. Boil the sunken wood with water: If you use sunken wood and other substances as decorations in the fish tank, you can boil it with water before putting it in, so as to avoid the phenomenon of water yellowing.
3. Change water regularly: In order to avoid water yellowing, it is necessary to change water regularly. Especially in summer when the temperature is relatively high, water exchange needs to be more frequent.
4. Clean up the medicine or change the feed: If it is caused by the medicine, the residue of the medicine needs to be removed after the fish disease is cured. If it is caused by feed, other kinds of feed can be replaced.
