What harm does the green water in the fish tank do to the fish?

We know that water quality is a major influencing factor for fish culture. sometimes in the process of fish culture, we will encounter the situation that the water color turns green. In serious cases, the fish in the fish tank looms and even dies! Why is that? Is green water not suitable for fish to grow? Not all green water is not suitable for fish life, goldfish is very suitable for breeding in green water.

If the water in your aquarium tank turns green, it only means that there are a lot of algae (green moss) in the water, which can be removed when necessary. Because the algae will absorb oxygen and release CO2 at night, it will reduce the oxygen in the fish tank and increase the carbon dioxide, which will greatly reduce the dissolved oxygen in the fish tank water and pose a great threat to the survival of the fish. If there are no large fish in the fish tank, or the outdoor fish pond is not a big problem, because the outdoor fish pond light is strong and long, the moss can not be completely cured.

In the process of raising goldfish, we like to make the water green, because green water is good for the fish; sometimes we don't want it to turn green, the green water will not only affect the viewing, but also worsen the living environment for the fish. There are actually many ways to control the turning green of water bodies. Here is a brief introduction:

1. Reduce the nutrition of water.

This is a headache for many aquarium experts, and the solution is to change the water (especially the bare tank), change the water, and then change the water. While changing water, strengthen filtration and make use of a powerful nitrification system to prevent the production of toxic ammonia nitrogen and nitrite.

2. Avoid sunlight

Practice has proved that the growth of algae is the fastest under the irradiation of natural light, especially the green moss will grow explosively, so it is necessary to set up an Arbor to shade or use a newspaper to cover the sun. The fluorescent tubes used in our aquarium lighting will also lead to incomplete chromatography due to aging, resulting in the proliferation of algae. If possible, you can turn on the UV lamp (ultraviolet germicidal lamp) and irradiate it for one to two hours a day. If you are exposed to water, you can add another two hours, which is also very effective.

I believe some fish friends should know that it is very good to raise goldfish in the old water, and the appearance of the old water is greenish and yellowish.

Old water is what we pursue, but it is very important to raise water in the early stage of fish culture, which is the process of turning new water into old water. Green water is also good for goldfish. For example, green water can make goldfish darker, but if there are too many algae in the water to see the fish, it is not suitable for viewing. And when there are too many algae, the fish will lack oxygen, so using green water to raise goldfish should pay attention to control the amount of algae in the water. It takes skill.

So much for the above. I hope it can help you. If there are any deficiencies, I hope you can give us your advice.
