1、注意天气变化,及时增氧换水。黄梅天常出现雷雨和闷热天气,气压较低,加上水温持续升高,鱼虾等摄食量增大,排泄物也增多,水质极易恶化,造成缺氧。因此,每天要及时开增氧机增氧。如碰到异常天气,应适当延长开机增氧时间,以保证池内有足够的溶氧量。同时,要勤换新水,隔天换去底层水10-15cm,促进池塘上下层水体交换,维持水质稳定。
1, pay attention to the weather changes, timely replacement of oxygen for water. Huangmei often appear thunderstorms and hot weather, low pressure, coupled with the water temperature continues to rise, fish and other food intake increases, excrement also increased, easily deteriorated water quality, resulting in hypoxia. Therefore, every day to open aerator oxygen. If you encounter abnormal weather, should be extended boot time oxygen to ensure that the pool has enough dissolved oxygen. At the same time, to diligently new water, the next day to the bottom of the water 10-15cm, to promote the exchange of water between the upper and lower ponds to maintain water quality and stability.
