Please note that unfortunately many suppliers often sell supposedly harmless, fine black sand. Such sand is not a natural product but rather broken, finely ground slag, i.e. a waste product from the blast furnace industry. Many shrimp farmers report that with this "sand" they unfortunately repeatedly have shrimp die and lose many animals. To protect yourself and your animals from such surprises, make sure when buying that the sand has no sharp edges and is not shiny like glass.
