Natural river gravel for universal use in aquariums and gardens of the “forest in a jar” type.
The product has a fraction of 2 to 4mm. It is perfect as decorative gravel, as an aquarium substrate for plants, and as a drainage of water in vases.
River gravel is the safest aquarium and gardening substrate, because it does not change the pH of water and soil, does not introduce a surplus of macro and microelements, is completely resistant to water, and does not change its properties over time.
