Talking about the advantages and disadvantages of keeping fish in green water

The old green water, also known as 'fat water', water quality is opaque, visibility is only 3-4 CM. the first formation of bright green, looks very comfortable green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green. Algae in the water is unusually rich, the development of the peak stage, but to reach the peak at the same time the process of water quality degradation has also begun, at this time we must ensure that the fish pool filtration system is open 24 hours a day to prevent the collapse of the "back to green".

Water color is a reflection of good or bad water quality. Observing water color not only plays an important role in preventing fish disease, but also is a more concise and convenient way to judge the quality of water.

The water is brownish in color, with more humus in the water, and is acidic.

The water is light red in color, with low dissolved oxygen in the water and few phytoplankton and many water fleas.

The water is yellowish-green in color, with a lot of phytoplankton in the water, especially diatoms, and less green algae.

The water is colorless and extremely clear. It's pure water, right?! Who would use this water for fish?

Generally speaking, water that is teal brown, yellow-green, grass-green, or cyan in color, the water is more suitable for fish.

The water is blackish brown, orchid green, grayish yellow, light red, and unsuitable for fish.

Grayish-white water is not suitable for fish if it is caused by deteriorating water quality, or fish if it is not caused by deteriorating water quality.

Transparent young green water in the spring, summer and fall are easily converted to old green water, if it has been converted, by changing the water is difficult to make the water back to clear, only to maintain not "green" can be.

Old green water is mostly used in outdoor patio and balcony for fish farming, which is one of the best water for traditional fish farming method, but this water has two sides.

If your water has become or has the potential to become old green water, you are urged to learn about the advantages of old green water. This water has a lot of algae content photosynthesizing during the day, producing oxygen and breaking down fecal matter and other dirt, creating a virtuous cycle that acts similarly to the nitrifying bacteria in Western fish farming theory.

Green water is rich in color enhancing substances, which is good for improving the color of the fish. And the planktonic green algae in the green water is also a very good auxiliary feed for goldfish is conducive to enriching the nutrients intake of the fish, which is beneficial to theImprove the quality of reproduction in the beginning of spring.

Fish kept in green water are usually in better shape and have black-green feces. In spite of this, the old green water is an uncompromising double-edged sword. If you do not grasp it well, the fish will suffer from it or even be completely wiped out. Reasons are as follows: algae in the water during the day to produce oxygen, but at night to consume oxygen, coupled with the fish itself, oxygen consumption, the water body after a night, the oxygen content in the dawn reached its lowest point, the fish is light floating head, daybreak algae can produce oxygen when the natural relief, or heavy "pan pan" death is a common occurrence.

Secondly, goldfish are prone to scalded tail disease. In summer, the light is strong, the algae in the water grows rapidly, photosynthesis is vigorous, and air bubbles are constantly produced. If you fail to feed in a timely manner or insufficient food, the fish will move around to look for food, air bubbles will continue to adhere to the tail, fins, so that the tail fins floating on the water surface, the head down, and then by the scorching sun, so that the caudal fin tissues are injured and congested with blood, suffering from scalded tail disease, wounds are most prone to infections, and in severe cases of tissue ulceration and infection death, even if healed tail fins are also small so that the quality of the appearance of the greatly compromised or even the loss of ornamental value.

Anyone who keeps koi knows that all koi have to produce scarlet to look good, and green water is very good for the development of scarlet color. Green water also provides nutrients: unicellular algae can provide koi with a more balanced nutrition, especially nutrients that are insufficient in some feeds, e.g. proteins, vitamins, etc. Unicellular algae can provide this, which is of course the reason why many people want to keep green water.
