Please check the following based on your intended use↓

【For use as aquarium substrate】
The material is natural clay fired at high temperatures, making it highly porous and excellent for bacterial colonization, thus purifying water.
It has a proven track record of being used as a filter medium for breeding Red Bee Shrimp, which require careful water quality management, so it will not negatively affect water quality. However, we cannot take responsibility, so if you are concerned, please perform water quality checks before use as a precaution.
*When using in an aquarium, the powder from friction during transport may cause cloudiness, so please rinse thoroughly before use.

【For use as decorative sand for houseplants】
Its porous nature and excellent water retention allow it to be used similarly to specialized hydroponic media or hydro-balls for houseplants?

【For use as gravel in your garden】
10kg will cover an area of approximately 1m x 1m with a depth of just under 1cm.
If using for weed prevention, we recommend a depth of 5cm or more.
Combining with weed-blocking sheets can further enhance the weed prevention effect.

【Product Condition】
