There are four main sources of ammonia nitrogen in ponds: fish, shrimp and crab manure, fertilizer, bait, and animal and plant carcass decomposition and ammonia nitrogen in underground sediment water.

[Scope of application] shrimp and crab, fish, sea cucumber, shellfish, turtle, frog and other aquatic animals.
[Main functions and features]
1. The effect of reducing ammonia and nitrogen is not rebounded significantly: This product is a living bacteria and does not contain any chemical components. Under the action of mixed flora, the source materials of malodor-ammonia, nitrogen, etc. are difficult to synthesize.
2. Prevent ammonia nitrogen, nitrite and stable water, and keep "fat and tender".
3. The effect of lean water is remarkable.
[Usage and dosage] This product is best immersed in a small amount of brown sugar (molasses) for 2-12 hours.
1. When ammonia nitrogen is less than 1.0: 50 g / mu • m for 2 consecutive days, a total of 100 g / mu • m.
2. Ammonia nitrogen is in the range of 1.0-2.5: the dosage is 70-100 g / mu • m, used twice.
3. In the case of thin water, ammonia nitrogen exceeds the standard: it should be used with molasses (brown sugar) and a small amount of fertilizer and aquatic products. In the case of water and fertilizer, it can be used alone.

Details
The ammonia nitrogen in fish ponds comes from bait, aquatic animal excrement, fertilizers and animal carcass decomposition, etc. The ammonia nitrogen content is too high, which will affect the growth of fish. If it is too high, it will cause fish poisoning and death, which will cause significant losses to production.
In the aquaculture process, high levels of ammonia nitrogen in ponds often occur. Excessive ammonia nitrogen will cause the immunity and resistance of farmed fish and shrimp to decline, reduce food intake, slow growth and be prone to disease. This article discusses the formation of ammonia nitrogen in ponds, the harm of ammonia nitrogen, and the control methods of ammonia nitrogen for farmers to effectively prevent and control the production of ammonia nitrogen in aquaculture production.
First, the ammonia nitrogen in the pond mainly comes from four sources, fish and shrimp manure, fertilizer, bait and animal and plant carcass decomposition and ammonia nitrogen in underground sediment water.
Second, the harm of ammonia nitrogen to aquatic animals. The harm of ammonia nitrogen to aquatic animals is divided into acute and chronic. The hazards of chronic ammonia nitrogen poisoning are reduced food intake, slowed growth, molting failure, tissue damage, and reduced oxygen transport between tissues. Fish, shrimp, and crabs must be ion-exchanged with water. Ammonia nitrogen can increase the permeability of gill filaments, damage the ion-exchange function of gills, keep aquatic organisms in a state of stress for a long time, and increase the susceptibility to animal diseases. It most often causes rotten gills and black gills in river crabs, slowing down growth and eventually dying. Acute ammonia nitrogen poisoning is manifested by aquatic organism excitement, loss of balance, convulsions in water, and severe death.
Ammonia nitrogen degrading agent capable of degrading ammonia nitrogen function bacteria
Zhengzhou Bangheng Biotechnology Co., Ltd. is committed to solving the water quality problems of aquaculture water, microbial water purification agents, functional bacteria that degrade ammonia nitrogen, and functional bacteria that degrade nitrite. Aiming at the excessive ammonia nitrogen in fish pond water, the company has a probiotic formula for degrading ammonia nitrogen-functional bacteria that can degrade ammonia nitrogen, which can reduce ammonia nitrogen exceeding standards, prevent subsalts and stabilize water, improve water quality, stabilize algae, and significantly reduce lean water.
This product is a live bacteria without any chemical ingredients. Under the action of mixed flora, the source material of malodor, ammonia and nitrogen, is difficult to synthesize. It can also prevent ammonia nitrogen, nitrite and stable water, and maintain "fat, lively and tender". And the effect of lean water is significant!
This product is effective when soaked with a small amount of brown sugar (molasses) for 2-12 hours.
1. When the ammonia nitrogen is less than 1.0: 50 g / mu · m for 2 consecutive days, a total of 100 g / mu · m.
2. Ammonia nitrogen is in the range of 1.0-2.5: the dosage is 70-100 g / mu · m, used twice.
3. In the case of thin water, ammonia nitrogen exceeds the standard: it should be used with molasses (brown sugar) and a small amount of fertilizer and aquatic products. In the case of water and fertilizer, it can be used alone.
4. When the amount of ammonia nitrogen exceeds 3.0 and the input is too large, it should be comprehensively treated: material cut-off, ammonia nitrogen reduction, fertilizer water, and bottom modification can be effective, or guide customers to use this product for prevention.
5. Prevent ammonia nitrogen, nitrite and stable water, and keep "fat and tender": the success rate is more than 80% (use once every 5-7 days, the dosage is 30-40 g / mu · m, when the water is thin, use a small amount of fertilizer and water Products; when water and fertilizer, use this product alone).
6. Significant lean water effect: (67 g / mu · m)
7. This product can be used in combination with the bottom modification bacteria for 2 days to effectively solve the problem of black water (this product is 50 g / mu · m + bottom modification bacteria 67 g / mu for 2 days).
8. For the ammonia nitrogen produced by the blackened sludge fish pond, it is recommended to use potassium persulfate to change the bottom to oxidize the bottom, and then reduce the ammonia.
9. This product can be pressed with Yuanming powder, citric acid, and adhesive to form bio-bottomed tablets.
