Reservoir silt and coral bleaching and seawater acidification have always been an important issue in Asia. We use the high permeability water of the reservoir to simulate the function of corals. Its function can be used to filter water quality and filter impurities into small fish food. The bony reefs that look like nature can not only help the fish to achieve the function of asylum, the natural holes can also make the eggs safely hatch, increase the hatching rate of the fish, and add the oyster shell powder, its alkaline characteristics are used to improve Acid and alkali in water, reducing the degree of acidification of seawater, while raw materials are natural waste sludge to achieve the goal of sustainable environment The attached factory is a reservoir mud that we promote together with local ceramic factories.
