Why does the water in the goldfish bowl turn green and how to solve it?

When the water in a goldfish tank turns green, it is usually caused by the green algae in the tank growing too fast. If the light is too strong, the fish tank is too small, the feeding density is too high, too much food is fed, or the nitrification system in the tank is not functioning properly, the green algae will grow easily, and the water in the tank will turn green easily. If the water in the tank turns green, you can change the water first, reduce the breeding density appropriately, and cultivate nitrifying bacteria in the tank. If that's not enough, you can keep one or two scavenger fish in the tank to help clean up the green algae.

1. why does the water in the goldfish tank turn green

? The water in the goldfish tank turns green because the green algae grow crazily. There are several reasons for this:

1. The light is too strong: When the light is too strong, the green algae in the water grow faster, so the fish tank can not be exposed to direct sunlight.

2. Excessive feeding density: When the fish tank is too small or the fish feeding density is too high, there will be more sundries in the water, which will lead to the overgrowth of green algae.

3. Feeding too much food: If the breeder feeds too much food, the fish will not finish it, which will cause the food to rot in the water and become the nutrients of green algae.

4. Abnormal nitrification system: When the nitrification system is in trouble, the green algae will also grow very fast.

2. How to solve

the problem that the water in the goldfish tank turns green? If you find that the water in the goldfish tank turns green, you can take the following methods:

1. You can raise two scavengers in the tank, which can play a better cleaning effect.

2. Change the water again and strengthen the filtration in the tank. As far as possible to maintain every two days to change a new water, a change of water should not be too much, to maintain a quarter of it. In addition, the filter cotton should not be changed too frequently, because it can promote the establishment of nitrification system, and is also conducive to the reproduction of nitrifying bacteria.
