How to cultivate green water for fish farming?

Natural clean water (rainwater, well water, river water, spring water) is stored in a pottery jar, placed in a cool and humid outdoor environment with fresh air, and a little duckweed is stocked, which can be obtained in half a month on a hot day.

The best green water culture is to put the fish tank in a well-lit position, put in fresh water to avoid direct sunlight and astigmatism, and then raise the water first (that is, cultivate the ecosystem first) like normal water fish culture. When the system in the storage tank is initially completed,

You can set the fish free (the water is still clear in normal color at this time). With the introduction of fish, the ecology will gradually stabilize over time (like aquatic plants, the formation of green algae also needs nutrition), so the management during this period is particularly important.

In the process of maintaining green water, we should control the light green water quality to prevent it from developing into dark green water quality. Fish raised in tender green water have the largest appetite, strong body, bright color and rapid development.

Advantages of green water;

Under photosynthesis, carbon dioxide and ammonia are consumed, producing a lot of oxygen. Raising fish in water with high oxygen content is helpful to stimulate appetite and grow quickly and healthily, especially for some species with sarcoma (Lanshou and Lionhead). Because of photosynthesis, nitrification is skipped without producing its by-products, nitrite and nitrate.

Green water is the cheapest, simple and effective natural filtration system with natural and efficient filtration function. Green algae will take over the expensive and slow maintenance filtration system. There is also a gradual change in pH and temperature in green water, which makes it resistant to diseases. Algae contain a very high protein content of 60%, which is necessary for the development of Lanshou and Lionhead Sarcoma.

It also contains fresh carotene, which can promote the coloring of goldfish. In addition, the outdoor pond is also a hotbed for mosquito larvae to hatch, and also provides an important supplement for goldfish food. Goldfish is in a green environment, which can soothe (calm) and reduce the sense of urgency. And green water is a sign of goldfish's health. If the water turns brown-green, there will be a problem.
