JBL Sansibar Dark is a natural substrate for any aquarium. JBL Sansibar Dark is a fine, rounded dark sand of volcanic origin. It is gentle on the sensitive barbels of bottom-feeding fish such as cory catfish and loaches. The black gravel prevents light reflections. It makes easily frightened fish feel visibly more comfortable and display their full natural brillant colours. JBL Sansibar is ideal for plant care. The fine grain size and dense layering prevent sludge and other debris from seeping in, thereby preventing decay processes which could hamper plant growth. JBL Sansibar Dark does not release hardness-producing substances or undesired silicates into the aquarium. Grain size: 0.2 - 0.5 mm.Aquarium Substrat Calculator

very nice. Not totally black, a bit more to dark gray. Nice, _a bit_ glimmering / shiny effect from the light.Markus B. at 03.01.2016:
Super Sand, schön schwarz, sieht nicht künstlich aus!Es fehlt allerdings der Hinweis dass der Sand magnetisch ist. Davon wusste ich nämlich nichts, ich habe ohne weiteres Wissen meinen Klingenmagnet genutzt und mir ein paar schöne Kratzer in die Scheibe gemacht.

I bought JBL Sansibar Black. Is this necessary to clean it or rinse it with water before putting in Acquarium or we can put directly in the aquarium? Because when I bought it store person said no need to clean it it's already is. Just want some clearification.
Aquaristikshop.com: The gravel is very clean, but during the transportation there are some worn with fine particles, which can be removed by rinse the gravel.- Jussi K. wrote about JBL Sansibar Dark (Black) in 2016:
