[Scope of application] Shrimp, crab, sea cucumber, eel, turtle, yellow croaker, sea freshwater fish, etc.
[Usage and Dosage] 1. This product is highly active and does not need to be soaked.
2. The reduction of nitrite is 200-250 g / mu / m, which can usually be solved once. This product is matched with ammonia nitrogen-effective bacteria 20 g / mu / m. The nitrite is particularly serious, and it should be used again every other day.
[Main functions and features]
1. This product is live bacteria, does not contain any chemical ingredients, and the effect of reducing nitrite is not rebounded; the effect of reducing nitrite is significant.
2. Under the action of mixed flora, the source substances of malodor-ammonia, nitrogen, etc. are difficult to synthesize
3, this product has a significant water regulating effect, not only lowered the nitrite, but also adjusted the algae phase, bacteria phase, the water color after use is beautiful and fresh.

Details

The levels of nitrite, ammonia nitrogen, hydrogen sulfide, ph value, and chemical oxygen consumption in the aquaculture water body will determine the quality of the aquaculture water. During the aquaculture process, if the nitrite, ammonia nitrogen, hydrogen sulfide, ph If the value is too high, it will bring great harm to the aquatic animals that are farmed. How to solve such a water quality problem? What if the degradation of nitrite decomposes ammonia nitrogen and regulates water quality?

Performance of fish and shrimp nitrite poisoning

Nitrite is highly toxic to fish and shrimp. The mechanism of action is mainly to reduce the ability of fish blood to transport oxygen. Nitrite can promote the conversion of hemoglobin in the blood to methemoglobin and lose the ability to combine with oxygen. Brown blood disease. " In the early stage of poisoning, the appetite of the fish decreased, anorexia, slow response to avoidance, shortness of breath, and floating heads (most of the anoxic floating-head fish can be clustered, but nitrite poisoning is different, and fish are unevenly distributed throughout the pond, everywhere); In the later stage of poisoning, the body color becomes darker, the turbulence or the unresponsive liver changes, such as vacuoles, lesions in the gill tissue, swelling and proliferation of the gills, and dark red gill filaments, making it difficult to breathe.

Main causes of excessive nitrite levels in fish ponds
1. Unreasonable feeding
If the amount of bait is too large, the fish will be over fed, and some of the feed will be excreted into the water before it can be digested. In addition, some feeds will fall directly into the water. The decomposition of these excreta and baits in the water will produce a large amount of ammonia and Toxic substances, after the action of nitrosating bacteria and photosynthetic bacteria, are quickly converted into nitrous acid, which is combined with some metal ions to form nitrite.
2. Unreasonable fertilization
In many farming areas, fish is still farmed using a combination of feeding and fertilization. Unfermented organic fertilizers and fertilizers such as ammonium bicarbonate are used. These fertilizers produce a large amount of ammonium nitrogen in the water body. Converted into nitrite under action.
3. Silt at the bottom of the pool
The sludge at the bottom of the pond is not cleared for a long time. The sludge is decomposed and fermented during the breeding process, consumes oxygen, and generates a large amount of nitrite in the fermentation process.
4. The breeding density is too large, and the amount of feed fed is also large, which is likely to cause hypoxia in the water body and the decomposition of nitrogen-containing organic substances to produce ammonia.
Method for degrading nitrite functional bacteria in Zhengzhou Bangheng
Functional bacteria that degrade sub-salts directly splash water on the fish pond. A variety of probiotics quickly dominate the water body, killing and inhibiting harmful bacteria and viruses in the fish pond, and purifying the water quality. At the same time, the probiotics quickly deposit bait and Fish manure is transformed and decomposed into nitrogen-containing organic matter and small molecule organic matter, which can provide zooplankton and beneficial reabsorption, prevent oxygen consumption of fish manure from decomposing and decomposing, gradually increase the dissolved oxygen content in the water body, and fundamentally inhibit the generation of nitrite. The nitrite produced in the fish pond is transformed by nitrifying bacteria into non-toxic and harmless substances such as nitrate under aerobic conditions; denitrifying bacteria reduce nitrite to N2 or nitrogen oxide compounds under anoxic conditions Non-toxic and harmless substance, effectively reduce the content of nitrite and adjust the stable pH value.
Nitrite in fish ponds is an intermediate product in the process of ammonia conversion to nitrate. Residues left by a large number of baits in aquaculture water, accumulation of large amounts of excreta from aquatic animals in water, and regular disinfection of use. Pharmacy, killing harmful and beneficial bacteria, insufficient supply of oxygen, causing a large amount of accumulated nitrogen nitration process to be blocked, forming high levels of ammonia nitrogen and nitrite nitrogen in the culture water, but due to the rapid conversion rate of ammonia nitrogen, The problem of nitrogen nitrate is the most prominent.
