How to raise the water temperature and water level in aquaculture in spring?

As the temperature drops, the water quality in many ponds becomes weak. The water quality of fish ponds should be fatter. In sunny weather, it is necessary to fertilize and cool the water to ensure sufficient dissolved oxygen and stabilize the water quality. Fish ponds can use chemical fertilizer first and then organic fertilizer.

If the water quality is unstable, photosynthetic bacteria should be used to stabilize the water body; If the water is thick and dark, Bacillus or lactic acid bacteria should be used to decompose organic matter and purify the water.

The water level in the shrimp pond should be deepened (1.6~ 1.8m), and the water should be fertilized to protect algae (transparency 30~40cm).
