Problems related to aquaculture in seas and lakes are solved with the heavy metal treatment agent 'TERRAST'.

A large amount of iron ions leaches out in water over a long period! It can also be easily applied to concrete structures.

The phenomenon of kelp bed degradation in Hokkaido, whitening of cultivated nori, and the death of seawater pearls are said to be largely caused by a lack of nutrients (phytoplankton) due to mass aquaculture production. Phytoplankton can be easily proliferated by iron ions. Our patented 'Iron Terrast (Fe-TERRAST)' can release iron ions stably, quantitatively, and in large amounts over a long period, and it can simply be spread in aquaculture areas or hung around cultivated products. If you have concerns related to aquaculture in the sea or lakes, our product can solve them. Please feel free to contact us when needed. 【Features】 ■ Manufactured using patented technology that binds iron and carbon ■ A large amount of iron ions is released over a long period in water ■ Can be easily applied to concrete structures like tetrapods ■ By rolling it as a tablet on the seabed and applying it to concrete structures, it is possible to promote the growth of seaweeds and also create good fishing grounds by serving as a reef. *For more details, please refer to the PDF materials or feel free to contact us.
