the yellow water in the fish tank, the best way is to change the water, which can quickly improve the water quality. It should be noted that the water can not be completely changed, otherwise it will lead to fluctuations in the water body, which is harmful to the health of fish. Usually a third at most is changed at one time, but normally a quarter or a fifth is enough. In addition, the temperature before and after the change of water should be consistent, and too large temperature difference will stimulate the fish body.
? 1. The outbreak of brown algae: The reason why the water turns yellow is probably the outbreak of brown algae. This is a kind of algae that is easy to grow in an environment lacking light. If you want to control it, the best way is to add light to the fish tank. It can provide 4-10 hours of light every day. The time can not be too long, otherwise it will promote the reproduction of green algae.
2. Feed fading: If the feed contains certain pigments, it will also cause the water in the fish tank to turn yellow. In view of this situation, the best way is to replace the feed. However, in order for the color of the fish to be bright, it is necessary to feed more food that can produce color, such as shrimp meat.
3. Sunken wood and yellow water: If you put sunken wood in the fish tank, it will also cause the water to turn yellow gradually, but this is harmless to the fish, but it will only affect the viewing. If you want to solve the problem of yellow water, you need to boil it in the pot several times first, and then put it in the jar, it is not easy to yellow water.
