Dupla Reef Ground Sand 0.5-1.2mm – 3L

Dupla Reef Ground is an ultra-pure natural aragonite of fossil origin, used as a substrate for all marine aquariums. Its purity makes it extremely bright with high light reflection, an advantage for light-hungry corals, and it is an environmentally friendly alternative to natural coral sand. This pack is 0.5-1.2mm grain, 3L.

Working out how much you need

To estimate the amount, multiply your tank’s length by its width in centimetres, then by the depth of sand you want, and divide by 1,000 to get litres. The 3L bag suits nano reefs, refugiums or topping up an existing bed, while the 20kg sack is the practical choice for larger systems. The 0.5-1.2mm grain is fine enough for sand-sifting gobies, wrasses that bury themselves at night and burrowing invertebrates. Dupla gives the composition as 99.2% calcium carbonate and 0.4% magnesium carbonate, with only a trace of iron, so it adds very little that you would not want in a reef tank.

Good to know

Rinse the sand thoroughly before adding it to the aquarium.
