Akadama stone from the island of Sado in Japan has been known as one of Japan's three famous stones - one of the other fabled types is known as the famous "bug-eaten rock" or Hakkai Stone.

Sado-Akadama stone comes from a special part of Sado island, where Mr. Takashi Amano composed a book about the island, labeling it "Japan's last wilderness." With special permission from the Japanese government, a limited quantity of this stone has been made available for the Nature Aquarium - and once supply in Japan runs out, it will never be harvested again.

Featuring red and yellow coloration, this stone gives a very raw and dramatic iwagumi or driftwood layout. You won't want to miss out on this one.

• Price is per pound, where 1 quantity = 1 lb, it is recommended to have 5 lbs for Mini S and Mini M series aquarium, 10 lbs for Mini L and 45-P series, and 20 for 60-P series.
