Case four: Fujian Longhai Jiao Mei, a 6.5 acres of shrimp pond, density of 55,000 tails / acre, 10 days after the seedling, began to use the "Fordyce Ann" 6.5 mu / bottle, every 4 days to change the bottom, a month later, the bottom of the bottom is not black, does not smell, no sludge, nitrite has been very low, 65 days of aquaculture, shrimp specifications to achieve 55 tails/catty, mu yield of 1000 pounds.
Case 1: Liaoning Donggang Zaogou Zhang boss of 50 acres of sea cucumber circle, found in June around the net reef sea cucumbers have "swollen mouth", "skin" phenomenon. He went down to observe and found that the bottom mud had been blackened and stinking, and the sea cucumbers were dead. "Fudian II" 3mu/bottle, used for three days, a week later, "swollen mouth", "skin" phenomenon is obviously reduced. Ten days later, we went down to observe, the bottom mud was yellow, no fishy odor, no dead sea cucumbers were found. (Note: The dosage of "Fudian" in this case is too large, and the deterioration of the substrate, the organic matter is too much and the seawater aquaculture is related, the next two cases are the same situation).
Case 2: There is a sea cucumber circle in Donggang, Liaoning, during the high temperature period in summer, the moss is rotting, the bottom of the pool is black and stinky, the sea cucumbers crawl abnormally, and some of them "spit out their intestines" (dirty) and "turn into skin". Use "Fudian II" 3mu/bottle+Bottom Oxygen (Enhanced) 3mu/bag, localized dosage, once a day, for three consecutive days. The sea cucumber basically returned to the reef, no more "spitting", "skin" phenomenon.
Case 3: Liaoning Linghai, sea cucumber circle, 50 acres. 2014 March ice period, pool water black, dark, a lot of rotting moss at the bottom of the pool, water quality, substrate aging, sea cucumbers "swollen mouth", "black mouth". Using "Fudian II" 1~2mu/bottle, the phenomenon of "swollen mouth" and "black mouth" of sea cucumber is obviously relieved.
Case 1: Hubei Xiantao Shahu town clamped the river village Zhu master a 17 acres of 2-year-old grass carp adult ponds, in mid-August, the pond began to appear in the evening every day back to the bubbles, to the next morning, the entire pond covered 2/3, after observing the bottom of the anoxic fermentation formation, the use of "Fordyce Ann" to change the bottom, for two consecutive, and with the opening of the aerator, three days, the bottom of the pond, the bottom of the pond, and the bottom of the pond, and the bottom of the pond. With the opening of the aerator, 3 days later, this symptom is reduced, and then adhere to the use of "Fudian" every 7 days to change the bottom, and then no longer this situation occurs.
Case 2: Tianjin Beichen Lixinhe a carp farmers, many years do not clear the pond, the bottom of the pond silt is very thick. Summer high temperature period, reflecting the feeding table under the "bubbles", people walk around bubbles bubbles more, the use of "Fudian" 5 mu / bottle, feeding table under the more thrown a few pieces, with the second day after the bottom of the pool is not bubbling, after seven days and started bubbling.
Case 3: Hainan will Wen Qingge Li boss high pool culture of large gentian (grouper), due to the daily feeding of a large amount of fish feces a lot of often encountered can not be discharged, the use of "Fudian Ⅱ" half a bottle, only sprinkled in the middle of the sewage outlets, generally 2 to 3 days after the sewage can be smooth. He also specializes in bringing a water mirror down to the outfall to see, row before the very black, sprinkled with "Fortean Ⅱ" after the sewage, the sand around the white."
Case: Hubei Xiantao area, net box farming eels, a large number of feeding chilled material, net box in the dirty especially more, residual bait is easy to odor, in each net box into the "Fortean Ⅱ" 3 to 4 tablets, used 2 to 3 times a week, eel feeding good. Long-term use of the fish found in the net box under the silt is very thin.
Case: A village in Wubao Town, Jiangdu, Jiangsu Province, because of continuous cloudy days, the water body became muddy after the "inversion of algae".

Case: Hebei Tanghai County, ten farms, Li boss, 10 acres of ponds, water depth of 1.4 meters, breeding South American white shrimp. August 3, 2013 customers reflect the shrimp eating poorly recently, the pond side to observe the color of the water for the soy sauce color, the bottom of the pond appeared to be a large area of the "white film", with a triangular mesh to observe the bottom of the mud black and viscous, there is a bad smell. The use of "Fortean Ⅱ" 5 mu / bottle, the beginning did not feel the "white film" to reduce how much, but the deodorant effect is very good, the shrimp eating significantly better, with the third time, the white film began to decrease.
Case 1: Tianjin Ninghe Panzhuang Meng boss, elite South American white shrimp pond, an area of 20 acres, water depth of 1.8 meters. One night "inverted algae", shrimp floating head, the use of oxygenator (sodium percarbonate) effect is not obvious, the bottom layer of dissolved oxygen has never come up in 2 to 3mg / L or so, followed by the use of the "Fordyce Ann" 5mu/bottle, the bottom layer of dissolved oxygen to reach 3mg / L or more, floating head! The phenomenon of floating head is obviously alleviated.
Case 2: Hunan Changde rock mouth village Li boss, a 5 acres of new pond, aquaculture grass carp. July 23rd at three o'clock in the morning, the grass carp floating head serious, the morning of the use of "Fortean Ⅱ" one and a half bottle (3 acres/bottle), 24th morning, the grass carp floating head significantly reduced.
Case 3: Nantong City, Jiangsu Province, Rudong County, Weihai Village, Pan boss, 50 acres of soil ponds, in the breeding process is very important to the dissolved oxygen, the home is equipped with two sets of dissolved oxygen meter, every day to observe the daily changes in dissolved oxygen, generally high during the day, the night to reduce. After using several times "Fudian II" 5 mu/bottle, I found that the rate of dissolved oxygen reduction at night slows down, and after half an hour of using the drug, the dissolved oxygen does not go down.
Case 1: Doumen, Zhuhai, Guangdong, a shrimp pond, the water depth of 1.2 ~ 1.3 meters, pH value of 8.0 ~ 8.3, nitrite higher than 0.3mg / L, more than a month. After the daily use of "Fudian" 6 to 8 mu / bottle, the night with "Oxygen Speed Protection", 5 to 7 days after the nitrite down to 0.1 to 0.2mg / L. Local experience, the frequent use of "Fudian" ponds, although the nitrite is not as high as 0.2mg / L. Local experience, often use "Fudian" ponds. Local experience, the regular use of "Fortean" pond although nitrite is also high, but reduced the bottom of the oxygen-consuming substances, so there will be no dead shrimp. The same conditions without the use of "Fortean" other ponds, it is easy to die shrimp.
Case 2: Jiangsu Sheyang Chen boss, there is a 110 acres of main silver carp pond. Starting in May with "Fordyce Ⅱ" 5 mu / bottle, every 7 days with a breeding process, nitrite from no more than 0.1 mg / L, at the end of June when the local nitrite is generally very high, the boss of the pond nitrite is also 0.1 mg / L, and the breeding process basically did not use fertilizer, 10 days with a "three times a day", "three times a day", "three times a day", "three times a day", "three times a day", "three times a day", "three times a day", "three times a day", "three times a day". The owner of the pond also had a nitrite of 0.1 mg/L at the end of June when the local nitrite was generally high, and basically did not use any fertilizer during the breeding process.
Case: Jiangsu Sheyang Wu boss 160 acres of grass carp, crucian carp mixed ponds, in previous years will be outbreaks of cyanobacteria, in April this year has been full of cyanobacteria, and the water is black. Started to use "Fudian II", 5 mu / bottle, used twice, the water color from black to green, cyanobacteria also significantly reduced, and then insisted on 7 days once, 12 mu / bottle, June cyanobacteria on the absence of, until the beginning of August have not found a large number of cyanobacteria. Introduced to the neighbor Sun boss with, cyanobacteria is also no longer.
Case: Shandong Haiyang area, car shrimp, pike crab mixed pond. In the middle and late aquaculture often appear algae red tide, when serious, can cause shrimp and crab hypoxia, poisoning, death, loss is very large. In this case, many farmers use "Fudian Ⅱ" 5 mu / bottle, "Bishui An" 3 mu / bottle treatment, according to farmers reflected: through this treatment, no stimulation of shrimp and crab, does not affect the growth, but also effective in improving water quality, red tide is much less harmful.
Case 1: Shandong Laizhou area, the old pond of marine aquaculture turbot is often fed fresh fish, organic matter, a lot of moss in the pond, and more than the inlet and outlet, the use of "Fortean Ⅱ" 4 to 5 mu / bottle and "bottom of the house" control moss! The effect is obvious. After the moss dies in the pond, use "Fortean" 5mu/bottle, and the dead moss will float to the surface. Long-term use of "Fudian" 4-5 mu/bottle, the original long moss pond no longer long moss, after two years of continuous use, the bottom of the pond no longer moss growth.
Case 2: Shandong Wendeng Chen boss sea cucumber breeding pond, area 20 mu, water depth 1.4 m. In early May 2015, the water temperature 15 ℃, moss (yellow tube vegetable) a lot of decay, the bottom of the pond black, stink, dissolved oxygen 3.3mg / L, rotting moss sea cucumber appeared "swollen mouth", The sea cucumber at the rotten moss had "swollen mouth", "spitting intestine" and "skin melting". Use "Fordycean Ⅱ" mu/bottle + "Bottom dwelling safety (strengthened)" 4 mu/bag + "Bottom oxygen (strengthened)" 4 mu/bag, use 2-3 times for serious cases, and find that the blackened bottom becomes yellow obviously. The bottom of the pond turns yellow, and the sea cucumbers have less "swollen mouths", "spitting intestines", and "skinning", and the ponds that are not treated have less "swollen mouths", "spitting intestines", and "skinning". "The pond without treatment, the sea cucumber "swollen mouth", "spitting intestine", "skin" is very strong.
Case: Hebei Huanghua, a pike crab set car shrimp pond, pike crab just put seedlings soon, the customer reflects the pond downwind water glowing, pond observation downwind a large number of deaths of copepods, sampling and inspection, copepods surface a large number of fluorescent Vibrio vulnificus, the use of "Fotilette Ann Ⅱ" 5 acres/bottle, the whole pool sprinkler, downwind threw more than a few pieces, the next day disappearance of the water body. The next day the water body luminous phenomenon disappeared.
