Review: Dénomination granulométrie grossière inexacte - Ce sable n'est absolument pas adapté aux aquariums récifaux où le brassage est fort à cause de sa granulométrie trop fine. La dénomination "Grossière" porte à confusion et mensongée, puisque la granulométrie est d'environs 1 à 1,5 mm. Je dois renvoyer l'article.
