What kind of water quality is best for keeping goldfish?

As the saying goes, "fish culture first raises water", and the quality of water environment directly affects the life and health of fish. So, what color of water is more suitable for fish farming? What kind of water can be called "good water"? Therefore, as a senior fish farmer, we must know how to observe the color of water quality and distinguish the quality of water.

From the perspective of professional science:

1. When the water is brown, it means that there is more humus in the water, and the water is acidic at this time;

2. When the water quality environment is red, it means that the dissolved oxygen in the water is relatively low, there are fewer phytoplankton and more Daphnia.

3. When the water turns yellow-green, there are more phytoplankton in the water environment, especially diatoms, but less green algae.

If your water is colorless and transparent, it is usually pure water. As a professional fish farmer, you generally don't use this kind of water to raise fish directly (such as pure tap water and well water, which can't be directly used to raise fish). )。

Some netizens once concluded that when the water turns brown, yellow-green, grass green and cyan, it is more suitable for fish farming. On the contrary, if the water environment is blue-green, grayish yellow and reddish, it is not suitable for fish farming.
