Signs before the fall of algae

The sign before the algae fall is that there will be a layer of yellow floating matter-like or oil-film-like dead algae in the pond, the viscosity of the water will increase, the foam will be more, large, and it is not easy to disperse for a long time, and some foams even show a dirty khaki. It usually occurs in spring, and a large number of algae die in the pond, which will reduce the dissolved oxygen of the water and speed up the digestion of oxygen in the water, resulting in anoxic asphyxia of fish.

How to prevent algae from falling?

It is necessary to strengthen daily inspection, along with the observation of water body changes and various indicators of water quality. Always observe the weather forecast and beware of continuous high temperature, torrential rain and other extreme weather. When the transparency of the water body becomes worse and begins to become turbid, there is a prelude to algae falling. At this time, new water can be injected, or water purification agents can be used to adjust, and geological improvements can be carried out with bottom reagents to avoid algae falling. Can open more aerator, when there is water layer separation and insufficient dissolved oxygen, it can provide sufficient oxygen supply.

After the occurrence of algae dumping, attention should be paid not only to detoxification and water transfer, but also to geological improvement. first, the detoxification agent should be sprinkled in the whole pool for anti-stress hurdle, and at the same time, in order to avoid lack of oxygen in the water body, open more oxygen boosters and cooperate with chemical oxygen enhancers such as oxygen, to avoid fish hypoxia. In the case of sufficient water, the technology is injected with clean new life, and the algae are re-cultivated.

The above is the introduction of the signs before the fall of algae. I hope it will be helpful to you.
