How to remove green algae in fish ponds

Moss in fish ponds is the general name of several filamentous green algae such as Spirogyra. The growth of moss in fish ponds seriously affects the water quality of ponds, leading to the decrease of plankton, slow growth of fish and even the death of fish species. So there are several common methods to remove pond moss: 1. Plant ash Method: Choose sunny morning, and use 25-30 kg of plant ash (dry ash) per mu of water surface. 2. Pig manure removal method: 250 kg ~ 300 kg of fresh pig manure is used in each mu of fish pond, and moss is scattered in dense areas, and the moss is generally removed within 10 day. 3. Application method of maple leaf juice: use 30 kilograms of maple leaf per mu of water surface, add 50 kilograms of water to 100 kilograms, boil for half an hour, and sprinkle the cooked maple leaf juice all over the pool water. Generally, pond moss can be completely killed after 4 days. 4. Pinus massoniana leaf method: soak 20 kilograms of fresh Pinus massoniana leaves in each mu of fish pond, grind and add water to make 25 kilograms of pulp, and spread it all over the pond once a day for 2-3 days. 5. Copper sulfate elimination method: 0.7 grams of copper sulfate per cubic meter can eliminate moss. 6. Blue alum elimination method: 2 kg ~ 3 kg of blue alum is used for each mu of fish pond, and 20 kg of water is sprayed between ponds. Generally, moss can be eliminated in 5 days. However, the dosage of blue alum should not be too much, so as not to kill fish and cause unnecessary losses.
