Aragonite Sugar-Sized Sand: 0.2 – 1.2mm diameter grain size. Also known as “oolitic sand,” this grade is ideal for shallower beds allowing de-nitrification in little 1″ depth. The fine sand can pass easily through gills of gobies and other sand-sifting organisms. Smooth round grains are gentle to soft bellied sharks rays. White color metal free, no ash or silica. CaribSea Aragonite buffers to the highest pH and delivers more calcium, carbonate, and trace elements than any other substrate. Little or no rinsing required, aragonite keeps aquariums healthier, longer.
