对虾养殖场必备品（Essential for prawn farm） Essential for prawn farm Lime, zeolite powder, tea meal, activated carbon, molasses Environmental conditions are closely related to the success or failure of shrimp aquaculture, and extreme environmental conditions and rapid changes in environmental factors are not conducive to the survival and growth of tang shrimp. Therefore, the management of water quality in the management of shrimp is very important. Water quality management includes water quality testing and water quality control. How to prevent water quality to change rapidly, how to respond appropriately when the water quality changes rapidly, is an important but difficult problem in aquaculture. This paper will recommend some of the essential products for shrimp farms, their use and usage. If prawn farms can be used in a good way, they will have an unexpected effect on stabilizing water quality and solving water quality problems. A, lime 1. Lime use There are four main types of lime: (1) quicklime Calcium oxide (CaO) is produced after combustion of natural limestone. Add calcium oxide to water and it will heat up and the pH of water will rise. (2) slaked lime Calcium hydroxide Ca (OH) 2 is produced after hydrolysis of calcium oxide. (3) general lime (agricultural lime) Calcium carbonate CaCO3, made of natural limestone ground. (4) bitter soil Calcium carbonate Ca. MgCO3, made of natural dolomite. 2. The function of lime (1) sterilization and sterilization, using raw lime. (2) improve the pH of the pool water and use slaked lime. (3) improve the total Alkalinity of the pool water and use regular lime, bitter soil or lime. The use of lime and the timing of its use (1) sterilize the shrimp after harvest Use quicklime. Add 10 to 20 cm of shrimp water, spread lime on the pond evenly, stir to mix the lime and water and bottom soil. If you can sprinkle lime water on the pool wall, it is best. Usage is 150 to 300 kilograms per mu. (2) improve the total Alkalinity of pool water The
