Soil preparation for creating a suitable environment for bivalve growth: "Clear Water"
The main component is a highly safe, seawater-derived magnesium ingredient! To improve the growth rate of bivalves, we propose enhancing the bottom quality of the release site.
By applying the sediment improvement agent "Clear Water," we suppress the generation of hydrogen sulfide and contribute to creating a soil environment where bivalves can safely inhabit after release. This product mainly consists of magnesium extracted from seawater, and its safety for scallops has been confirmed. It also has a high safety profile for humans, plants, and fish. The effectiveness of this product in suppressing hydrogen sulfide and reducing benthic organisms has been verified by the Ministry of the Environment's ETV program. ★Usage location: Bivalve release sites and others 【Features】 ◆ Weakly alkaline … Maintains a weakly alkaline pH of around 9 to 10 ◆ Long-lasting effect … Slowly dissolves in water, providing sustainability ◆ High safety … Safety has been confirmed through safety tests (OECD standards, etc.) ◆ No special equipment required … Can be applied directly from above the water surface without special equipment 【Mechanism】 ■ By maintaining the sediment in a weakly alkaline state, we suppress the activity of sulfate-reducing bacteria that cause hydrogen sulfide generation. ■ Reduces hydrogen sulfide damage to bivalves and contributes to improved survival rates. ■ Maintains a pH conducive to the activity of organisms that decompose sludge, promoting sludge decomposition. *For more details, please feel free to contact us.

Company information
Ube Materials Corporation is a manufacturer of specialty inorganic materials based in Ube City, Yamaguchi Prefecture. Using limestone, which is abundantly produced in Mine City, as raw material, the company produces calcium-related products such as quicklime and hydrated lime, as well as extracting magnesium from seawater using quicklime as a raw material to manufacture products like magnesium hydroxide and magnesia clinker (refractory material). Additionally, as a unique business, the company has developed a healthcare division that directly serves consumers by selling lime as a dehumidifying agent, and now offers products such as toothpaste, bath cosmetics, and other cosmetics through co-ops, mass retailers, mail order, and online sales.
