Yellow water in the fish tank is generally due to the aging of the water quality. Although it looks very clear, there will still be some harmful substances accumulated in the tank. Once it reaches a certain amount, it will cause harm to the fish, and even lead to their death. Usually, when it is found that the water body is yellow, it is necessary to shorten the water exchange cycle, as long as the water is changed frequently, the situation will soon be alleviated.
1. Feed problem: Not all feed can cause the water in the fish tank to turn yellow, but some of poor quality will cause yellow water after soaking in the water for a period of time. Therefore, the feed bought must be checked first, prepare a cup of tap water, soak for five to ten minutes, to see if it will cause the water to turn yellow.
2. Too much feces: If there is too much feces in the fish tank, it will cause the water to be polluted, which will also make the water yellow. In view of this situation, on the one hand, it is necessary to clean up the dirt at the bottom of the tank when changing water, on the other hand, it is necessary to reduce feeding, feeding less, and naturally less feces.
3. Place sunken wood: Some people like to put sunken wood in the fish tank. Although sunken wood can play a role in regulating pH, it can also cause the water body to turn yellow. If you want to avoid yellow water, you can boil the sunken wood in water for a few days, or soak it for several months before putting it in the fish tank.
4. Turn on the light for a long time: Do not turn on the light for the fish tank at all times. If the light is turned on for too long, it will easily lead to yellow water or green water. This is due to the outbreak of algae. Usually, the time to turn on the light is about 3-6 hours, if it is a grass tank, it can be a little longer, but not more than 8 hours.
