Why does the water in the pool turn green?

As we all know, water quality is the main factor affecting fish farming. Sometimes, in the process of raising fish, we will encounter the situation that the water quality turns green. Why? Is green water not suitable for fish growth?

If the water in your aquarium turns green, it means that there are a lot of algae (green moss) in the water, which should be removed in time. Algae will absorb oxygen and release CO2 at night, which will reduce oxygen and increase carbon dioxide in fish tanks, posing a great threat to the survival of fish. If there are few big fish in the fish tank, or the outdoor fish pond is not a big problem, as long as you don't think it will affect the viewing.

In the process of raising ornamental fish, sometimes we like to make the water green, and green water is good for fish; Sometimes I don't want it to turn green. Green water will not only affect the viewing, but also worsen the living environment of fish. In fact, there are many ways to control water greening. Here is a brief introduction:

1, reduce the nutrition of water?

This is also a headache for many aquarium experts. The solution is to change water (especially bare cans), change water, and then change water. Strengthen filtration while changing water, and use powerful nitrification system to prevent the production of toxic ammonia nitrogen and nitrite. ?

2. avoid light?

Practice has proved that natural light can make algae grow fastest, especially green moss will proliferate explosively soon. We should build a arbor to shade the sun, or use newspapers to shade the sun. The cathode fluorescent lamp used for aquarium lighting will also lead to incomplete chromatography due to aging, which will lead to algae reproduction. If possible, you can turn on the UV lamp (ultraviolet germicidal lamp) and irradiate it for one or two hours every day. If it's sun drying, you can add another two hours, which is also very effective.

Not all water can meet the needs of goldfish. The most suitable water for goldfish growth is old water. Hydroponics is the process of changing new water into old water. ? ?

I also want to tell you that old water is what we pursue. Take goldfish as an example. Green water is also good for goldfish. For example, green water can make goldfish darker, but there are too many algae in this water to see fish or fish. Moreover, when there are too many algae, the fish will lack oxygen, so we should pay attention to controlling the algae content in the water when raising goldfish with green water.
