This product is a highly efficient and non - toxic composite flocculant. It solves the technical problems that polyferric sulfate is difficult to solidify and granulate. It is for the first time applied to the new field of aquaculture in a breakthrough way. It is especially suitable for old ponds with excessive silt and ponds whose water turns black and stinks in the later stage of aquaculture. By evenly spreading it over the whole pond regularly, it brings unexpected effects of water purification, sterilization, iron supplementation, oxygenation, de - blackening, and deodorization to aquaculture users.

2. Scope of Application

Aquatic animal breeding ponds in marine and freshwater bodies, river treatment and restoration, especially suitable for old ponds with excessive silt and ponds whose water turns black and stinks in the later stage of aquaculture.

3. Usage and Dosage

Directly and evenly spread it over the whole pond.

Apply 1 kg for an area of 5 - 8 mu per meter of water depth. Increase the dosage as appropriate for poor bottom conditions. Halve the dosage for preventive bottom protection. It is recommended to use it once every 10 - 15 days.

4. Product Efficacy

4.1 Directly decompose organic matters such as residual bait, feces, animal and plant carcasses, and dead algae deposited at the bottom of the pond. At the same time, decompose the eutrophic bottom silt. After continuous use for 2 - 3 times, the black mud at the bottom of the pond is significantly improved.

4.2 Supplement iron elements to animals and plants, promote photosynthesis, enhance disease - resistance ability, strongly remove odors and other odor - causing factors, and inhibit and kill the growth and reproduction of odor - causing microorganisms.

4.3 Decompose the viscous substances in the aquaculture water body, reduce the surface tension of the water body, penetrate and regulate the water layer and dissolved oxygen layer, and increase the dissolved oxygen content at the bottom of the water body.

4.4 Degrade harmful substances such as ammonia nitrogen, nitrite, and hydrogen sulfide at the bottom, enhance the photosynthesis ability of the water body, and regulate and improve the water quality.

4.5 Regular use of this product can convert the sludge at the bottom of the pond into active silt, reduce the bottom heat, promote the well - developed root systems of aquatic plants in the breeding pond, purify the water quality, increase the dissolved oxygen, improve the appetite of aquatic organisms such as fish, shrimps, and crabs, and enhance their disease - resistance ability.
