Diatoms form brown algae layers that classically appear in a newly set-up tank after about one to three weeks. These algae coat every surface in the tank, like the substrate, technical equipment, plant leaves and the decoration. They can form very stubborn brown coats on the glass of low-light tanks. Diatoms are also called Bacillariophyta.
Indeed, despite several studies, potential species-habitat associations between epiphytic diatoms and different macrophyte species have remained relatively elusive, and it is probable that species-specific plant-diatom relationships are rare (Eminson and Moss 1980). There are some studies which do show strong host-plant links, however.
Within the cytoplasm, like other eukaryotic cells, diatoms contain organelles.There is a nucleus, Golgi complex, mitochondria, chloroplasts, and vacuoles that contain oil.Structurally, diatoms are generally made of two valves, which are flat, connected by a girdle band structure. One valve plate, the epitheca, is slightly larger than the other valve plate, called the hypotheca.

Identification of a species is important in the identification of drug-producing plants, toxic plant species, or illegally transported plants. Diatoms in stomach contents, lungs, or other tissues can be used in suspected drowning victims and may even be localized to a given body of water. They also are associated with many cleansers and polishes.
Diatoms are ubiquitous primary producers in marine ecosystems and freshwater habitats. Due to their complex evolutionary history, much remains unknown about …
Taking diatom samples is done by grinding the surface of seagrass leaves using a brush, while sampling nitrates, phosphates and silicates is done using a water sampler. The results of this study indicate that nitrate concentrations ranged from 1,250-1,255 mg / l, phosphate 0,031-0,570 mg / l and silicate 1,180-1,700 mg/l.

Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement. Fly ash can be used as prime material in many cement-based products, such as poured concrete, concrete block, and brick.
