Common methods for bottom water adjustment include physical, chemical, and biological methods. Physical methods are usually time-consuming and labor-intensive, and their effects are not very significant; There are many limitations on the growth conditions of microorganisms in biological methods, which often fail to achieve the expected results; However, traditional chemical methods often result in the accumulation of highly irritating or toxic by-products in aquatic animals, affecting the quality of aquatic products and causing secondary pollution to water bodies. With the continuous development and progress of scientific research, the "fifth generation new disinfectant" potassium monopersulfate composite salt, which can be called "green chemistry" and integrates "safety and efficiency", has emerged. It not only has efficient antibacterial and detoxifying abilities, but its oxidative decomposition products are carbon dioxide, water, and inorganic salts, just like microbial degradation products. Unlike microorganisms that are limited by many growth factors, it has become a new favorite in aquaculture.

The potential value of potassium hydrogen persulfate is as high as 1.85V, and its oxidation ability exceeds most oxidants such as chlorine dioxide, potassium permanganate, strong chlorine, hydrogen peroxide, etc. This potential value can oxidize most organic matter, reduce oxygen consumption factors, and alleviate sediment oxygen debt; And it can oxidize divalent iron in water to trivalent iron, divalent manganese to manganese dioxide, nitrite to nitrate, hydrogen sulfide and other sulfides to sulfate, eliminate the harm of these substances to aquatic animals, and repair the black hair and odor phenomenon in sediment; At the same time, potassium persulfate can degrade the residual chloramine after the use of chlorine preparations, reducing toxic residues. It can be said that potassium hydrogen persulfate tablets are currently the best substrate improvement product and the main substrate improvement product promoted by mainstream manufacturers. They have great prospects in the breeding of benthic animals such as South American white shrimp, loaches, eels, yellow catfish, and crabs.

During the process of disease occurrence, farmers using multiple disinfectants are still unable to treat the disease, mainly due to the long-term use of the same disinfectant leading to drug resistance of pathogenic bacteria. Potassium persulfate, due to its unique bactericidal mechanism, does not cause bacteria or viruses to develop drug resistance. At the same time, due to its safe concentration for fish and shrimp being higher than 100mg/L, normal or 2-3 times the dosage will not cause any stress to fish and shrimp. Therefore, when stubborn diseases in fish and shrimp cannot be treated, potassium persulfate products can be used twice in a row to kill pathogens that cannot be killed by chlorine agents or surfactants, achieving the goal of disease treatment. At the same time, in the breeding process of precious aquatic products such as special fish, shrimp, and fish fry, the use of potassium hydrogen persulfate composite salt products can achieve good preventive effects for various diseases such as Vibrio and bleeding, without causing drug resistance to pathogenic bacteria, and has a good effect on water quality improvement.

Potassium persulfate can not only kill plankton such as algae, but also eliminate biotoxins such as algal toxins. It is often used in the treatment of drinking water for humans and livestock, with mild properties and good safety. In pond aquaculture, the water body is not only a living place for fish, but also a place for the disposal of "garbage" such as feces and leftover bait. Due to the high density of aquaculture, the self purification capacity of the water body is limited, and the water quality often exhibits abnormalities, such as black and odorous water, concentrated green water, and algae deposition. Potassium hydrogen persulfate has strong oxidizing properties and can supplement the lack of reactive oxygen species in water bodies. At the same time, it oxidizes organic matter, ammonia nitrogen, sub salts, hydrogen sulfide and other substances that are harmful to fish health due to insufficient oxygen supply, achieving the goal of water quality control. In addition, potassium hydrogen persulfate has a good degradation effect on the large amount of algal toxins released under conditions of algal blooms and algal blooms. Therefore, after using potassium bisulfate, the water quality generally becomes noticeably fresher. If fish loss of appetite is caused by water quality issues, using potassium bisulfate composite products has excellent effects. The functions of these aspects are gradually being discovered by users, coupled with their excellent bactericidal effect, therefore, potassium hydrogen persulfate composite products are receiving increasing popularity.
