Calcium Carbonate Powder For Aquaculture

Our Calcium carbonate powder for aquaculture is specially developed and produced for aquaculture scenarios, using natural high-purity calcite and low-impurity limestone as raw materials, processed through fine grinding, impurity removal classification and hygiene control. The product has no harmful impurities and high safety, can release calcium slowly, regulate the pH of aquaculture water, and improve the sediment environment. It is an essential water quality conditioning and nutritional supplement raw material for shrimp, crab, shellfish, fish and other aquaculture.

In view of the application characteristics of aquaculture, we have specially optimized the particle size and purity of Calcium carbonate powder for aquaculture: the product has fine and uniform particles, good dispersibility after full-pond sprinkling, can be uniformly suspended in water and released slowly, avoiding local concentration surge that stimulates cultured organisms; meanwhile, harmful elements such as heavy metals, arsenic and fluorine are strictly controlled, which will not poison water, destroy algae balance, or accumulate in aquatic animals. Verified by years of field application in aquaculture, our Calcium carbonate powder for aquaculture can effectively promote shell hardening after molting of shrimps and crabs, reduce soft shell disease, stabilize water pH value, reduce breeding risks, and improve hatching rate and breeding density.

● Shrimp and crab aquaculture: Supplement water calcium ions, promote shell hardening after molting, and reduce problems such as soft shell disease and unsuccessful molting.

● Shellfish and marine aquaculture: Regulate water alkalinity and calcium concentration, promote shell development of shellfish, and increase breeding output.

● Water pH regulation: Stabilize the pH of aquaculture water, buffer water quality fluctuation, and maintain the balance of beneficial algae and bacteria.

● Sediment improvement: Improve aged pond bottom, alleviate sediment acidification, decompose harmful substances, and improve the breeding bottom environment.

● Aquafeed addition: Added as a calcium source to compound feed to supplement calcium nutrition for aquatic animals.

We take safety as the core control indicator of Calcium carbonate powder for aquaculture, and have established exclusive screening standards for aquaculture-grade raw materials. Heavy metals and harmful elements are tested from the raw ore stage, and high-impurity ore sources are rejected; dedicated production lines are used during production to avoid cross-contamination with industrial-grade products; each batch of finished products is tested for harmful components such as lead, arsenic and cadmium before leaving the factory to ensure that the products meet aquaculture safety requirements and will not cause secondary pollution to cultured organisms and water environment. Safety inspection reports are available for each batch of products.

We not only provide products, but also have a professional aquaculture technical team to provide full after-sales service. We can recommend the dosage and application scheme of Calcium carbonate powder for aquaculture according to customers' cultured species, breeding modes and water quality test data; provide targeted water quality adjustment suggestions for different scenarios such as earthen ponds, high-level ponds and industrial aquaculture. We can follow up water quality changes during the breeding cycle and provide adjustment guidance to help customers achieve the optimal balance between water quality stability and breeding benefits.

Adopt special moisture-proof packaging for aquaculture: 25kg film-coated woven bags (lined with double-layer PE film) or 500kg sealed ton bags to prevent moisture absorption, caking and impurity ingress during transportation. Products are stored in an independent dry warehouse, away from pollutants such as pesticides and fertilizers to avoid cross-contamination. Rain and dust protection are implemented throughout transportation to ensure products are clean and dry; the shelf life is 12 months under proper storage conditions. After opening, it is recommended to seal and use as soon as possible to avoid moisture absorption affecting the use effect.
