Fish first raise water
Water is the environment for fish to survive. Better water quality can reduce the occurrence of fish diseases and is more conducive to the growth and survival of fish. In actual production, water quality can often be judged by changes in water body color, ammonia nitrogen content, and sediment color.
1. The red water color of the red water pond is mainly caused by diatoms or golden algae becoming the dominant species. Usually, there is no serious problem, but once the weather suddenly changes and causes a large number of algae to die, toxins will be produced and the water body will deteriorate, and even directly cause Fish poisoned and died. Therefore, once the pool water turns red, it must be improved in time. When the weather is fine, first use Siji'an or quaternary ammonium salt iodine, etc. to spray and disinfect, and then spray with hydrogen peroxide, strong chlorine essence, etc. on the second day, and then top dress the fertilizer once after 3 days depending on the situation.
2. Black water When the pool water is black, it indicates that more organic matter in the pool has not been transformed in time, such as residual bait, animal remains, excrement, and humus at the bottom of the pool. Hydrogen, ammonia nitrogen, nitrite and other harmful substances endanger the health of aquatic animals, reduce their immunity, lead to the infection of pathogenic microorganisms, and even cause fish flooding in ponds. Once this kind of black water is found, apply chlorine-containing drugs such as dioxychloride once on the first day to the second day to oxidize too much organic matter. After 3 days, use Baifeng Vitality Water Purification Wang Quanchi to splash once.
3. White turbid water When the pool water is white and turbid, it indicates that there are too many organic oxygen-consuming substances in the pond. Relatively speaking, there are few microorganisms that decompose large-scale organic matter into nutrient salts. The material circulation in the pond is destroyed, the water in the pond is close to aging, and there is a severe lack of oxygen. The fish in this kind of pond are generally prone to floating heads from early morning to dawn before the sun rises. When the pool water is found to be cloudy, apply "Shui bao Oxygen Pack" on the first day to oxidize the organic matter in time after flocculation. On the second day, apply Bai feng Aquatic Bao once to the whole pool to increase the active microorganisms in the pool and promote water body circulation.
4. Water with high ammonia nitrogen content is fed with high-protein feed, chilled meat, or intensive fish ponds that feed on live fish, such as crab ponds, prawn ponds, snake head ponds, and mandarin fish ponds. After adding high-protein bait, the content of ammonia nitrogen in the metabolic products is too high, which will affect the feeding and growth of aquatic animals, reduce their immunity, and easily cause parasite or pathogenic microorganism infection. Therefore, for intensive ponds that feed on high-protein feed, chilled meat or live fish, apply ammonia or bottom net once every 10 to 15 days to degrade ammonia nitrogen in time. If through the water quality test, if the ammonia nitrogen content in the pool water is found to be seriously exceeding the standard, you should apply ammonia net and oxygen treasure to the pool in time, and then use fertilizer water element and fertilizer water treasure once on the third day to increase the active microorganisms in the pool and promote plank tonic The reproduction and growth of organisms enhance the material circulation capacity of the water body.
5. Due to the deposition of humus in the pool water, animal residues, bait, and feces sink to the bottom of the pool and then decompose, causing the bottom mud of the pond to turn black and stinky, which easily produces harmful substances such as methane, hydrogen sulfide, and nitrite. It is very easy to pose a threat to aquatic animals living in the middle and lower layers, such as crucian carp, grass carp, herring, crab, shrimp, mandarin fish and other species. When the situation is serious, the aquatic animals in the middle and lower layers of the pond often float in the middle and upper layers, and do not want to go to the normal living water layer. If the above situation occurs, apply Baifeng Aquatic Po every 10 days to 15 days to increase beneficial microorganisms, accelerate the transformation of organic matter or humus that sinks to the bottom of the pool, and avoid blackening and odor of the bottom mud and the production of methane, Harmful substances such as hydrogen sulfide and nitrite. If you find that the bottom mud in the pond is black and the water is stinky, you should immediately take measures to change the water. After changing the water, apply Vitality Clean Water King on the first day, and quick-acting fertilizer Shuibao on the second day to adjust the water quality.
