How to transfer the water in the fish pond and how to deal with the fish pond after adding water

Turning water refers to the serious lack of oxygen production capacity and self-purification capacity of the water body of the pond, resulting in the extremely low content of dissolved oxygen in the water body, the accumulation of harmful gases and substances, and the water body of the pond suddenly turns black and clear when the weather changes, and the fish pond can smell a strong fishy odor downwind, which then causes the phenomenon of fish floating for a long time. The transfer of water mostly occurs in the summer high temperature season, which finally leads to the occurrence of flood pond conditions, which brings serious losses to farmers. 1. Reasons for water transfer 1, fish mortality caused by deterioration of water quality When the water becomes old water and bloom water, the algae in the water multiply (too much algae), although a large amount of oxygen can be produced during the day, but the supersaturated oxygen overflows the water surface, the dissolved oxygen in the water does not increase, and the algae consume a lot of oxygen at night, when the dissolved oxygen in the water is insufficient, the algae suddenly die in large quantities, the water color becomes black and clear, the oxygen production in the water is reduced due to the death of algae, and the oxygen consumption increases, which is easy to cause the flooding pond and death of fish.

2. The death of algae caused by excessive fertilization When the water is thin, in order to fertilize the water, the farmers often apply a large amount of fertilizer many times, and the nutrients in the water are excessive, and the algae multiply in large quantities, resulting in water transfer. In order to make the water better as soon as possible, a large amount of fertilizer is applied many times after the water is transferred, which causes a vicious circle. 3. The algae mortality caused by the mass reproduction of zooplankton in the fish pond is out of balance, and there are too many zooplankton in the water body, such as rotifers, protozoa, cladoperas, etc., which swallow algae in large quantities, and the reproduction rate of algae is lower than the swallowing rate of zooplankton, resulting in the overproduction of zooplankton in the fish pond, and the water body has very low oxygen production capacity caused by water transfer.

Second, the way to prevent water transfer is to insist on pond dredging or ploughing to prevent too much silt at the bottom, which can treat both the symptoms and the root cause. The second is reasonable fertilization, can not be blind, it is recommended to use a small amount of chemical fertilizer, more use of biological organic fertilizer. The third is to add and change water frequently.

Fourth, while using fertilizer, live fungus biological agents are used to keep the algae phase stable for a long time. Fifth, when algae blooms, algaecide drugs cannot be used to kill them at one time, and local drugs should be used in places where there are too many algae. Sixth, when zooplankton reproduce in large numbers, they cannot be killed with insecticides at one time, and they should be used 1m along the edge of the pool.

3. The solution after the water transfer occurs In areas with convenient water sources, methods such as eliminating wastewater and adding new water can be adopted, which can solve the problem of water transfer. After the water is transferred, there may be a floating head or even a flooding pool, and the aerator should be started. On the one hand, it can rescue the floating head, and on the other hand, it can make the dead algae oxidize and decompose as soon as possible and reduce oxygen consumption.

Prepare high-efficiency aeration powder in case of power outages in the event of a lack of oxygen, resulting in huge losses. Aegradants are poured throughout the pond to increase dissolved oxygen at the bottom and promote the decomposition of dead algae deposited at the bottom of the pond. After the situation is basically normal, it is recommended to use microbial water quality improver and biological fertilizer to splash the whole pool.

Disinfectants should be avoided as much as possible during the water transfer, otherwise algae are less likely to bloom. When the water transfer occurs, there is a serious lack of oxygen in the water, and the fish float for a long time, which affects the growth. In this case, the whole pool should be sprinkled with water quality protection antidote, and then the algae growth promoter should be applied after the water quality is adjusted.

It's usually a good idea to pump the water out and wait for it to fill up, unless your fish pond is close to a canal, river, or next to a pond where you can divert or pump water to your own fish pond. In the rainy season, the water is stored quickly.

Summary. After adding water, wait for the odor and ammonia nitrogen in the water to disappear, and observe the reaction of the fish to ensure its healthy growth.

Can you add, I don't quite understand it.

Proper treatment needs to be carried out after adding water to ensure that the fish have a good living environment. First of all, it is necessary to check whether the rewaxing temperature and pH value of the fish pond water are normal, and if not, they need to be adjusted. Secondly, the right amount of oxygen needs to be added to ensure that the fish have enough oxygen**.

In addition, you can add the right amount of live bacteria and vitamins and minerals needed by fish. At the same time, the impurities in the water need to be cleaned up in time to keep the water quality clean. Finally, fish observation is required, and if there is an abnormality in the fish, it needs to be dealt with in a timely manner.

In short, the fish pond needs to be treated comprehensively after adding water to ensure the health and survival of the fish in the barrage.
