The water trickles through the trays, keeping the filter wool wet but not completely submerged, allowing aerobic bacteria to grow and aiding biological filtration. The water returns to the aquarium like rain. [14] Alternatively, the wet/dry filter may be placed below the tank. In this design, water is fed by gravity to the filter below the ...
Oatmeal's health benefits Oatmeal is made from oats — a whole grain that is a great source of fiber, carbohydrates and protein, plus vitamins and minerals including B vitamins, magnesium and iron.
Reoxygenating the system water is a crucial part to obtaining high production densities. Fish require oxygen to metabolize food and grow, as do bacteria communities in the biofilter. Dissolved oxygen levels can be increased through two methods, aeration and oxygenation. In aeration air is pumped through an air stone or similar device that ...
Roman plebeians "ate the staple gruel of classical times, supplemented by oil, the humbler vegetables, and salt fish" [5] for gruel could be prepared without access to the communal ovens in which bread was baked. In the Middle Ages, the peasant could avoid the tithe exacted by paying in grain ground by the miller of the landowner's mill.
For freshwater aquaria, gravel is the most common substrate. To prevent damage to fish, gravel should not be sharp. Aquarium gravel can be as coarse as pea-sized or as fine as 1–2 mm. [1] It is available in a number of colors, and may be naturally colored or dyed, and may have a polymer seal to ensure it does not affect water chemistry. [1]

Cereal β-glucans – including β-glucan from oat, barley and wheat – are linear polysaccharides joined by 1,3 and 1,4 carbon linkages. The majority of cereal β-glucan bonds consist of 3 or 4 beta-1,4 glycosidic bonds (trimers and tetramers) interconnected by 1,3 linkages.
