Does this sand suit your tank?
Four configurations are what this bag is made for: refugiums, plenum systems, fish tanks and reef tanks. Check that your tank is one of these before you buy, since the manufacturer lists no other uses for it.
The ooids run from 0.4 to 0.9 mm, and the manufacturer notes that the sizing may vary slightly from bag to bag. If your set-up needs a single fixed grain size, measure a sample first. One bag weighs 20 lb (9 kg, 320 ounce), so the number of bags you need depends on the footprint and depth of your own tank.

Grains, surface area and pH
The sand consists of ooids sized 0.4 to 0.9 mm, which the manufacturer says may vary slightly. Each kilogram of this material offers more than 1 million sq. cm of surface area, so a 20 lb bag carries that figure across roughly nine kilograms.
The material buffers and helps maintain a pH of 8.2, a stated property of the aragonite. It is also free of harmful tar, organics or impurities, according to the manufacturer. Grains in the 0.4 to 0.9 mm range are the fine grade the bag is sold as.
What the sand is made of
The grains are oolitic aragonite collected from the oceans of The Bahamas, and the material is 98% pure calcium carbonate. Aragonite is one of the crystal forms calcium carbonate takes.
