Why does the water in the fish tank turn green? What are the benefits of green water?

The reason why the water in the fish tank turns green is that the water body is over-nourished and full of light, which leads to the proliferation of algae, thus making the water body green. It is worth mentioning that green water itself is harmless to fish and even helps to some extent. It can be used as feed for some fish, and at the same time, it releases oxygen and absorbs ammonia nitrogen in water through photosynthesis, which is beneficial to the health of fish. 1. Why does the water in the fish tank turn green? The reason why the water in the fish tank turns green is that the water body is over-nourished and full of light, which leads to the proliferation of algae, thus making the water body green. It is worth mentioning that green water itself is harmless to fish and even helps to some extent. It can be used as feed for some fish, and at the same time, it releases oxygen and absorbs ammonia nitrogen in water through photosynthesis, which is beneficial to the health of fish.

Second, what are the benefits of green water? 1. Absorb ammonia nitrogen: The green color of green water is the color of Chlorella, while algae can absorb ammonia nitrogen in water, which is mainly produced by the decomposition of organic matter. In the absence of nitrification system, algae can be absorbed to avoid poisoning fish, which is equivalent to improving water quality.

2. Release oxygen: Algae is also a kind of plant, which can carry out photosynthesis, so they can release oxygen when the light is sufficient. It should be noted that you should not be exposed to light for a long time in order to improve the dissolved oxygen in water, which will lead to algae explosion, occupy a lot of space and affect the survival of fish.

3. As food: Some fish have a mixed diet and can eat algae, so green water can also be used as food, but the nutrition of algae is relatively simple, so for its health, it is still necessary to feed other feeds, otherwise the growth of fish will be bad.
