Suitable for raising hermit crabs, saltwater fish, and fish that prefer alkalinity.

Coral sand dissolves minerals into the aquarium water, maintaining a neutral to alkaline pH. This stabilizes water quality, making maintenance easier.
It also suppresses the growth of harmful bacteria and actively promotes the decomposition of ammonia nitrogen from fish waste.
Biological filtration fosters the growth of beneficial bacteria, creating a healthy environment.
For freshwater tanks, it's commonly used as substrate for African cichlids and hermit crabs.
Guppies and platies prefer slightly alkaline water, so they are compatible with coral sand.
It is not recommended for use with many medaka or goldfish. If using for medaka or goldfish, a small amount is recommended.
Using it without washing can cause cloudiness in the aquarium water, so we recommend washing it before use.
Origin: Coastal areas of Japan, such as Okinawa and Kagoshima.
