[Features] This product is yellow spherical particles, mainly due to the physical and chemical sediment ponds deterioration caused by elevated increase in the phenomenon of harmful substances. It can be used directly to throw in the bottom of the pond disinfection reaction, while taking advantage of the characteristics of the surfactant, on the water, the water turbid, the film too much dirt, water, suspended solids and other gum played clarify water, eliminate oil The role of aquatic plants for photosynthesis normally help. But also through the unique multi-micellar complex with water ammonia, nitrite, hydrogen sulfide and toxic amines combined into harmless compounds strong stability, control over time and irritation. The main components of four hydroxymethyl sulfuric acid phosphate, adsorbents, synergists, HA salt, chelates such as yellow granules [character] [] a functional use, rapid degradation of water bodies ammonia, nitrite, hydrogen sulfide and other harmful substances . Complete elimination of black sediment, fever, smelly, fishy acid corruption; promote self-healing capabilities bottom, prevent temperature stratification and bottom heat; 2, activation bottom, regulate water quality. Type of compaction, salinization and other aging-type and stench type a fundamental change in the bottom of the pond and improve water clarity, providing effective protection for the necessary prerequisites for plankton photosynthesis. 3, it is particularly suitable for water quality mutation, sediment during bad weather and the onset of improvement, can significantly improve the ability of anti-stress aquatic animals. 4, frequent use of the product can effectively improve the bottom self-healing capacity to prevent the deterioration of the bottom, water aging; also prevents moss formation. 5, a stable pH value of the bottom to prevent growth of pathogenic bacteria. Thereby reducing the incidence of the probability of yellow shrimp gills, dark spots, whitish muscle and other bacterial diseases. [Object] to adapt the product to adapt to sea, freshwater aquaculture species, fish, shrimp, crabs, eels, turtles, shellfish farming water. Dosage evenly spilled directly. 1. Prevention: 100g / 1-2 mu / m. 2. Deterioration of water quality: 150g / mu / m, every other day, consolidate, use once every 7-10 days. 3. Water stratification: first FDA 200 g / acre dry sprinkle the next day and live with algae fertilizer products, so in the end the Ministry of algae fertilizer. 4. Low rainy days and hot weather: FDA 250 g / acre dry shake, 6-7 days once, should increase dissolved oxygen, changing the bottom of the anaerobic environment. [Note] 1, when used to keep the water of dissolved oxygen in the 3mg / L or more; 2, should be used as soon as possible after opening; 3, in case of agglomeration, the product does not affect the results. Save [Storage] dark, sealed, dry place [Packing] 25kg / bag or 50kg / barrel [validity] years
