My rockery pool is covered with white stones. Recently, it was found to be covered with moss. What should I do?

Common methods for removing moss are as follows:

1。 Plant ash method: Choose a sunny morning, use 25-30kg of plant ash (dry ash) per mu of water surface, stand on the bank of the upper air outlet of the fish pond and spread it, so that the plant ash will be evenly covered with green mud moss. Generally, green mud began to die after 3 days of application in plant ash, and all died and sank within 7 days.

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 30kg of maple leaf per mu of water surface, add 50kg ~ 100kg of water, 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。 Masson Pine Leaf Method: After soaking 20 kilograms of fresh Masson Pine 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 per cubic meter. You can sprinkle 7 grams of copper sulfate to eliminate moss.

6。 Blue alum elimination method: 2 kg ~ 3 kg of blue alum is used in 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.
