It should be noted that the amount of compound iodine should not be too large. It should be used according to the dosage in the instruction manual. Generally, the concentration should be controlled to 0.1 ppm. The excessive concentration of iodine will not only prolong the active time of iodine in the pond, but more importantly, the excessive dosage of such iodine preparation will also be toxic to aquatic products.
Compound iodine can also be used to treat bacterial or viral diseases. In this regard, compound iodine has extraordinary efficacy. For example, some stubborn rotten gills can be well controlled as long as you stick to using compound iodine for half a month. However, when you use it, you should pay attention to that the iodine concentration should be lower than 50ppm, otherwise it is toxic to fish, In addition, the disinfected water [purple solution is 2% methyl violet solution, which is also called gentian violet.
Can compound iodine be used in shrimp ponds in rainy weather
The compound iodine in shrimp ponds cannot be used in cloudy and rainy weather. Generally, the compound iodine preparation is used in the morning or evening, because the compound iodine preparation is easy to decompose after encountering light, and the light is usually weak in the morning or evening, which is conducive to the efficacy. 2 It is not allowed to use compound iodine preparation in rainy days to avoid hypoxia, and it is also not suitable to use it at noon, because there is strong sunlight at noon, which is easy to reduce the efficacy.
Disinfection time of compound iodine aquatic products
Generally, on the second day after the second insecticidal treatment, the whole pond mouth is disinfected with compound iodine solution. The best disinfection time is in the sunny morning. In addition, use Jifukang to prevent the occurrence of gill rot disease at the pond mouth
What surfactants are used in the preparation of complex iodine solution
What surfactants are used in the preparation of complex iodine solution
Surfactant refers to the addition of a small amount of substances that can make the interface state of its solution system change significantly.
Surfactant function: the molecular structure of the surfactant is amphiphilic: one end is a hydrophilic group, the other end is a hydrophobic group; Hydrophilic groups are often polar groups, such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amino groups and their salts, and hydroxyl, acylamine, ether bond, etc. can also be used as polar hydrophilic groups; The hydrophobic groups are often non-polar hydrocarbon chains, such as those with more than 8 carbon atoms.
Surfactants are divided into ionic surfactants (including cationic surfactants and anionic surfactants), non-ionic surfactants, amphoteric surfactants, compound surfactants, other surfactants, etc.
