Dry sugar sized aragonite sand substrate for marine aquariums
Functional marine substrate buffers aquariums from pH swings
Fine grains pass easily through sand sifting aquarium inhabitants
This super-fine sand (0.2 to 1.22 mm grain size) is ideal for shallow static beds and bottom covering of up to 1" in depth. Also known as "oolitic" sand, this sugar-sized sand naturally aids in the reduction of nitrates. Its fine round grains pass easily through the gills of gobies and other sand-sifting organisms. The smooth, round grains are gentle on soft-bellied sharks and rays. Pure and safe - metal, ash, and silica free. White in color. 30 pounds.
Determining how much substrate to buy for your new aquarium depends on the size and shape of your tank, as well as the depth of the substrate bed you wish to achieve. Another factor is the type of aquascaping structure you're planning.
Refugiums, small aquariums that either sit next to or hang onto an existing saltwater or reef aquarium, are used by a growing number of aquarists to continually cycle water into and out of the existing tank.
