How to remove algae from fish ponds, how to remove algae from fish tanks

1.Apply plant ash.

Method: Choose a sunny day in the morning, use 25 kg of grass ash (dry ash) 30 kg per mu of water surface, stand on the shore of the wind outlet of 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: 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.

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.

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 grass and wood ash fiber burial method: choose a sunny morning, use 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 vertical wood ash on the grass mountain, and all the dead sink within 7 days.

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

The use of nitrifying bacteria can be more effective in the passage (some very stubborn ones need to be removed by hand). It only takes about 3-7 days to remove all the algae and restore the clarity of the water. Of course, the cause is not 1-2 days, don't rush to give nitrifying bacteria some time, but also improve the filtration system and the overall water indicators (increase the frequency of water change and resale rate, strengthen physical and biochemical filtration, reduce feeding, change filter cotton, strengthen oxygenation), so that you can get twice the result with half the effort.

Summary. Hello dear, I'm glad to answer for you; The method of dealing with the green algae in the fish pond is: the reason why the green algae will grow in the fish pond is essentially because the water body is too fertile, and the nitrogen, phosphorus and potassium elements in the pond are too high.

Usually soak in water with copper sulfate or mix with quicklime and bleaching powder, and splash the whole pond once a month, which can not only eliminate green algae, but also disinfect and sterilize.

Usually soak in water with copper sulfate or mix with raw stone macro oak ash and bleaching powder, and splash the whole pond once a month, which can not only eliminate green algae, but also disinfect and sterilize.

My fish finger posture is not big, probably.

Six or seven cubic meters of water only before, originally crystal clear, during the National Day, no one at home, it just so happened that the water pound was broken, there was no circulating water for a few days, the water quality was rapidly poor, how to make the water quality change this good? What medicine to use and how much?

If you want to make the water quality of the fish pond better, you can change the water, top dressing, aeration, and bottom change.

1) Inject new water frequently. (2) Reasonable application of organic fertilizer and chemical fertilizer in closed land. (3) Scientifically use an aerator to agitate the water layer into a simple crack to increase oxygenation. (4) For blue-green water and brick-red water, copper sulfate, complexed iodine and insecticides can be used locally if necessary.

Medication ratio: 500 g of copper sulfate, 10 kg of quicklime, 30 4okg of water (or prepared with ketone sulfate, quicklime, water in a ratio of 1:20:(60 80)).
