Aquael Basalt Gravel 2 - 4 mm[Weight - 10kg]

Aquael's basalt substrate is a soft and natural substrate distributed in the aquarium. The black basalt gravel creates wonderful contrasts in the tank due to its dark color.
The natural substrate is characterized by containing no additives or industrial coatings, making it behave neutrally in water and not release any pollutants. The substrate features a very fine grain size ranging from 2 - 4 mm, and it is also ideal for aquariums containing shy fish that prefer a dark substrate for camouflage purposes.
Natural sand and gravel are available in a wide range of grain sizes and colors. They are carefully washed and free of impurities. Sold in durable plastic bags weighing 2 kg or 10 kg. They do not affect aquarium water standards (the above does not apply to dolomite gravel, intended for tanks that save native fish from Lake Malawi and Tanganyika).
