In the early stage, the products of other companies were used to change the bottom and transfer water, but after many times of treatment, the effect was not obvious, and the water body was still red. Xiao Liu, a technician of the company, went to the scene to learn about the situation, and took water samples to test: the water quality index was normal and there were too many rotifers in the water. It is analyzed that the redness and foaming of water bodies are mainly caused by rotifers and other zooplankton. Treatment method: dry sprinkle soil with 2 mu per bag in the morning, sprinkle it with avermectin 2 hours later, sprinkle it with 2 mu rice water per bottle of detoxifying stress essence in the afternoon, and use half a bucket of ecological fertilizer and water ointment + Lvshui No. 1 (3 mu / bag) on the second day, the water body turns green obviously on the third day, and the effect is particularly good.
