Quicklime can be used as a pH regulator in water, so how do we adjust it? The water quality of the breeding water body is extremely acidic and aging, especially in the hot summer and autumn seasons, when patina water (green) appears in the pond water, 20-25 kg (kg) of quicklime per 1 metre deep water body is used, and the whole pond is spilled after being dissolved by water For more severe conditions, it can be used again the next day. When the pool water contains a large amount of cyanobacteria, which is thick green and blue-green, hydrated lime can be used to kill excessive cyanobacteria. The amount of quicklime is 1 to 30 meters per acre in deep water.
Quick lime reacts with water to generate strong alkaline substances, adjust the pH of the pool water, maintain the stability of the acid and alkali in the water body, and form a water environment that is beneficial to the life of fish. Especially in ponds where crustacean aquatic animals such as shrimps and crabs are mainly cultivated, quicklime is used regularly to adjust the pH of the pool water to stabilize the pH between 7-8 and increase the calcium content of the water body. For the shelling and growth of crustaceans The formation of chitin is beneficial. Quicklime also regulates the substrate. For long-term feeding of feed water, the bottom mud of the pond is acidic, which is conducive to bacterial reproduction. Too much silt in summer and autumn is particularly likely to cause hypoxia and fish disease. Using quicklime whole pool splashing, after acting on the bottom of the acidic pool, the pH value of the bottom material will increase, which will help decompose the humus at the bottom of the pool and inhibit the reproduction of bacteria.
At the same time, through the use of quicklime, calcium ions free from water can replace nitrogen, phosphorus, and potassium in the sludge, increasing the fertilizer required for the growth of aquatic plants. Therefore, Jiangsu Dongchang Environmental Technology said that for ponds deep in sludge, Making one quicklime is equivalent to making one fertilizer.
Adjusting the substrate with quicklime can effectively increase the hardness and alkalinity of the water body, inhibit the strong change of pH value, improve the utilization of carbon dioxide by photosynthesis, keep the dissolved oxygen in the pool water at a high level, and create a good environment for the growth of aquatic animals .
