Soil texture refers to the proportions of sand (2.0 – 0.05 mm in diameter), silt (0.05 – 0.002 mm), and clay (less than 0.002 mm). The relative proportions determine the textural class. Soil texture influences nearly every aspect of soil use and management.

In typical rivers the largest carried sediment is of sand and gravel size, but larger floods can carry cobbles and even boulders. In a stream, the most easily eroded particles are small sand grains between 0.2 mm and 0.5 mm. Anything smaller or larger requires a higher water velocity to be eroded and entrained in the flow.
ASTM E11 specifies technical requirements for standard, alternative, and supplementary sizes of woven wire sieve cloth, sieve construction, frame sizes, and inspection of sieves and sieve cloth for sieves from 125mm to 20µm (5.0 to No. 635).

In addition, the quartz sand can also be used in soft water tanks, as it does not harden the water. The quartz sand is available in two different grain sizes. For large aquascapes, we recommend the 0,4 to 1,2 mm grain size. Both grain sizes are available in 2 kg or 10 kg bags. For small aquascapes, we advocate a 0,1 to 0,3 mm grain.
Sieve opening sizes are determined using imperial units for apertures 1/4in (6.3mm) or larger, and the indicated range of these openings varies from 5 inches (125 mm) to 635 mesh (20 microns). This establishes …
