How to treat green algae in lotus ponds? What to do if there is green algae in the pond

The lotus pond has the following measures for green algae extraction area:

1.Grass ash method: choose a sunny morning, each mu of water surface with 25 kg of grass ash (dry ash) 30 kg, standing on the shore of the fish pond tuyere throwing, so that the grass ash evenly covered on the top of the mud moss, generally apply grass ash 3 days after the mud began to die, 7 days of all death and sinking.

2.Pig manure elimination method: 250 kg of 300 kg of fresh pig manure per mu of fish pond, sprinkled in the dense place where the moss grows, and the moss is generally removed within 10 days.

3.Maple leaf juice method: 30 kg of maple leaves per mu of water surface, add 50 kg of water and 100 kg, boil for half an hour after boiling, and splash the boiled maple leaf juice in the whole pool. Generally, after 4 days, all the pond moss can be killed.

4.Masson pine leaf method: After soaking 20 kg of fresh Masson pine leaves in each mu of fish pond, grinding and adding water to form 25 kg of slurry, splashing the whole pool, once a day, using it for 2 days in a row and 3 days can be effective.

If it is particularly severe, it should be fished out by hand, put in the sun to die, and change the water. Just basically solve the problem. If you want to put some mussels, the effect is quite good.

1) Adsorption pretreatment (smell).

The establishment of powder activated carbon dosing device, the use of powder activated carbon at home and abroad to remove the color and odor substances in the water, has achieved successful experience to achieve the ideal treatment effect, the amount of powder activated carbon dosage and the turbidity of the water and the concentration of odorous substances are related, the dosage should be determined according to the water quality characteristics of the test. As a pretreatment method, powdered activated carbon has relatively high operating costs, and is generally used as an emergency measure to solve the sudden deterioration of water quality.

In Europe and the United States, powder activated carbon is widely used to remove the odor in the water in the water treatment, and the dosage is generally 2-5mg

<> Filling up new water: Filling the pond with new water, or replacing the pond water, or using micro-flowing water to breed aquatic animals.

Disinfection treatment: 10 kg of quicklime per mu is sprinkled in the whole pool, or bleaching powder with a concentration of 1ppm.

Manual removal: use nylon nets to catch green algae, and the green algae can be used as feed for livestock.

Biological control: Stock some black-shell shrimp, which will use green algae as food.

Deepening the water level: Deepening the pond water level will reduce the area where green algae can attach, speed up the sedimentation rate, and gradually die.

1. Fill with fresh water

1. When there is a lot of green algae, new water should be added, or the pool water should be replaced to improve the cleanliness of the water quality.

2. Usually add water regularly, or use micro-flowing water to breed aquatic animals, and the bad pond water can destroy the growth environment of green algae.

2. Disinfection treatment

1. Use 10 kg of quicklime per mu of pond to sprinkle the whole pond, or splash bleaching powder with a concentration of 1ppm.

2. Use organic fertilizer to avoid the aging of water quality and control the reproduction of filamentous green algae.

3. Splashing copper sulfate solution with a concentration can kill green algae.

3. Manual removal

Nylon nets are used to catch green algae from ponds, and the green algae can be used as feed for chickens, ducks, pigs and other livestock.

Fourth, biological control

1. Put an appropriate amount of black-shell shrimp, which will use green algae as food.

2. Put some fish with licking and scraping epiphytic eating habits.

Fifth, deepen the water level

1. Green algae are attached algae, and deepening the water level can reduce their attachment area and accelerate the sedimentation rate, so that they gradually die.

2. Set up aerators and wave machines in the pond to destroy the stability of the water body, which can also inhibit the reproduction of green algae.

Sixth, muddy mud water prevention

Add pig manure to the yellow clay (the amount of pig manure is about 30% of the yellow clay), mix it into a thin mud, and then splash it on the water surface, 1 time a day, 3-4 times in a row.

7. Combination of scrubbing and medicated bath

1. Scrub the green algae with waste polyethylene mesh, once every 2 months in spring and autumn, and only need to wash once in winter.

September is the peak season for the bloom of green algae, during which time it is washed once a month.

3. After scrubbing, soak it in copper sulfate solution with a concentration of 8ppm for 15-20 minutes, which can kill the residual algae species.

1. Use plant ash:

Each mu of water surface with grass ash (dry ash) 25 kg 30 kg, standing on the shore of the pond tuyere throwing, so that the grass ash evenly covered on the top of the green mud moss, generally apply grass ash 3 days after the green mud began to die, 7 days of all death and sinking.

2. Blue alum elimination method.

Each mu of fish pond is sprayed with 2 kg of blue alum 3 kg and 20 kg of water. Generally, moss can be removed within 5 days. However, the dosage of blue alum must not be too much, which will endanger the organisms in the pool and cause unnecessary losses.

3. Muddy mud water prevention.

Add an appropriate amount of pig manure with yellow clay (pig manure is about 30% of yellow clay), mix it into a dilute mud and splash it on the water surface, once a day, splash 3 times and 4 times, save labor and time, and the effect is good.

1. Part of the moss should be removed first, and 50% potassium bisulfate composite salt products can be used to kill locally at high concentration or by manual salvage.

2. Use sodium humate to shade and detoxify (it is best not to use it during the molting period), and deepen the water level to make the light not shine to the end and reduce the transparency.

3. Cultivating water, cultivating beneficial algae, and reducing light transmittance, so that the dominant population of moss is replaced by beneficial algae, using fertilizer water em bacteria (1-2 mu for 1 kg) + water beauty (phosphate fertilizer, per mu. 100 grams of rice and water) + 100 grams of algae per mu.

When the pond green algae is removed, it can be dissolved in copper sulfate soaked in water, and splashed once every month, and regularly disinfected and sterilized.

It is washed every two months in spring and autumn, and only once in winter, and is washed once a month from May to September, when the green algae bloom is at its peak, or the pond is stocked with fish that lick and scrape epiphytic food. Manual removal of green algae is laborious and incomplete, and at the same time of manual removal of green algae, some water ducks and black shell shrimp can be placed in the fish pond to prey on green algae, so as to control the large-scale reproduction of green algae.

Hello, the most effective is to use quicklime to completely clean the pond, and the source can effectively prevent moss breeding after killing the spores. It is suitable for ponds without shrimp, which is generally limited by the breeding mode, and this method is not easy to operate. 3. The most commonly used method is to maintain the water color by fertilizing water and inhibiting the photosynthesis of moss, thereby inhibiting its growth.

The difficulty lies in how to maintain the color of the water, too much fertilization in the early stage, which will cause the water quality of the pond to be too concentrated in the later stage, which is not conducive to breeding. In winter or the water temperature is low, it is difficult to fertilize with clean water, so it is not recommended to use phosphate fertilizer often in the breeding process.

1. Apply grass and wood ash method.

Choose a sunny day in the morning, 25 kg of grass ash (dry ash) 30 kg per mu of water surface, stand on the shore of the wind outlet on the fish pond and throw it, so that the grass ash is evenly covered on the top of the green mud moss, and the green mud begins to die after 3 days of grass and wood ash, and all die and sink within 7 days.

2. Pig manure elimination method.

Each mu of fish pond with 250 kg of 300 kg of fresh pig manure, sprinkled in the moss growth dense place, generally within 10 days to remove the moss.

3. Apply maple leaf sap method.

Use 30 kg of maple leaves per mu of water surface, add 50 kg of water and 100 kg, boil for half an hour after boiling, and take the boiled maple leaf sap and splash it on the whole pool. Generally, after 4 days, all the pond moss can be killed.

1. Apply plant ash: sprinkle the plant ash evenly on the green algae, and wait for about a week before it disappears. 2. Apply leaf sap:

Sprinkle the masson pine juice or maple leaf juice in the jar. 3. Raising animals: Raise scavengers, algae shrimp and other animals that feed on green algae in lotus tanks.

4. Improve the environment: shade the lotus pot and change the water every 3-4 days.

1. Apply grass and wood ash

Choose a sunny morning, cover the grass ash evenly on the green algae, after 3 days, the green algae will start to die, wait for a week before all sink and disappear, and try to avoid doing it on a rainy day, otherwise it will weaken the effect of removal.

2. Apply leaf sap:

Put the fresh masson pine leaves into the lotus pot to soak, after removing it, grind it into a pulp, splash the whole tank every day, and use it continuously for 2-3 days to be effective, in addition, you can also add water to boil the maple leaves, and then spray the maple leaf juice in the tank.

3. Raise animals

Scavengers, golden moss rats, algae shrimp and other animals can be raised in lotus tanks, they feed on green algae, which can effectively control the number of green algae, although it takes a long time, but it is safer and less labor-saving than applying algaecides.

4. Improve the environment

Green algae will grow very vigorously in a sunny environment, so proper shading can effectively curb its growth, and it is necessary to clean up the weeds and dead leaves in the lotus jar in time to avoid polluting the water body, and replace the water every 3-4 days to ensure that the water quality is clean.

1. Physical removal: Use a brush to clean the green algae on the wall of the pot, and then change the water for the lotus. 2. Chemical removal:

Dilute the algaecide with water and pour it into a lotus pot. 3. Biological removal: breeding black-shell shrimp, pipa rats, snails and other algae removal animals.

4. Precautions: Change the water quality for the lotus every half month to ensure that the water quality is clean.

1. Physical removal

After the green algae grows in the lotus pot, it can be eliminated by physical removal method, first remove the plant from the pot, and then use a brush to brush the green algae on the wall of the pot, and replace it with fresh and clean water, the disadvantage of this method is that the removal is not comprehensive.

2. Chemical removal:

For the green algae that is not easy to remove in the lotus pot, the algaecide can be diluted with water and poured into the pot, this agent has a strong effect on any algae, and the disadvantage is that it has a certain degree of impact on the ecological balance in the lotus pot.

3. Biological clearance

The green algae in the lotus pot can also be removed by biological control, that is, the cultivation of algae killers, such as white jade flying fox, pipa rat, snail, black shell shrimp, Yamato algae shrimp, etc., can be used to control the number of green algae.

4. Precautions

In order to prevent a large number of green algae from appearing in the middle and late stages of the lotus pot, the water quality needs to be changed every half a month during the maintenance period, and the water layer is controlled at about 3 cm in the early stage of growth, and phosphorus and potassium fertilizers are supplemented in time in the peak growth season to enhance the disease resistance of the plants.

The green algae you mentioned comes from moss, which has the effect of improving water quality, reducing toxicity and turbidity in the water. So as long as it's not a mass breed, some should be kept.

Ways to remove moss.

1 Manual cleaning, which is currently the most effective and direct method.

2. Feeding lichen fish and shrimp has a certain effect on moss removal.

3 Chemical killing, moss remover can be purchased from the aquarium store for chemical killing.
