Tropical River Sand by DOOA is a substrate for aquariums. It is a natural product from rivers and thus doesn't contain pices of corals. As a result the sand does not raise the hardness of the water. This sand is especially interesting due to the natural colour and gives a natural look to the aquarium, as it includes different grain sizes.
