In an aquascape the art is in creating a piece that is inspired by, and replicating nature. Aquascaping sand and gravel are graded by size and positioned in the aquarium to emulate scenes found in nature. Homogeneity, 'composition from like parts, elements, or characteristics' is a very popular and visually appealing aspect of an aquascape.
The composition of sand is highly variable, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and nontropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz.

We have this magnetite black sand in 5 lb, 20 lb, and 50 lb weights, which is made up of magnetite and hematite. We do not know the exact composition but we do know that it can be either, or both with other natural materials.
Two things determine the size of sand on beaches: the energy (height) of the waves, and the size of the material furnished to the beach. Other things being equal, the higher the average waves on a beach, the coarser the sand. This is because higher waves tend to move the smaller grains offshore to quieter water.
On river systems, current creates sand drops that offer excellent places for bass looking to hide out of the current. Look for sand drops at the bottom ends of running sloughs, along mainchannel islands, and behind wing dams. Aerial photography websites like google earth are great for finding sand drops, as they are often easily viewable.

It is a substitute for River Sand, it is also known as fine aggregates which is manufactured by crushing either granite or basalt rock using 3 stage crushing process by some companies. This sand is manufactured in conformance to IS Codes and is an effective alternative to river sand also known popularly as M Sand.

Many times, play sand is made of crushed rock instead of beach or river sand. This crushed rock or crystalline silica is already a known carcinogen according to the EPA and OSHA. In California companies are required by law to label products (thanks to California's Prop 65) that contain carcinogens.
Bedforms associated with sandgravel mixtures appear on the river bed immediately downstream of Yaalstrick Bar in a sequence (sand ribbons, barchans, dunes) suggesting sand deposition from suspension. There is also a dramatic increase in bar amplitude downstream of Yaalstrick Bar, suggesting greater sand composition. Our fluid flow and sediment transport measurements do not indicate any .
Seawater Composition. The most important components of seawater that influence life forms are salinity, temperature, dissolved gases (mostly oxygen and carbon dioxide), nutrients, and pH. Each of these is discussed below along with how it varies (or does not vary) and its influence on marine life.

Our river sand is natural sand and not a byproduct of crushed rock. It is composed of natural quartz (silica) grains, so it is a silica sand. We test all our river sand to make sure it provides a higher degree of hardness and durability in comparison to other sand providers.
