algae shrimp
Somewhat misleading vernacular name for the freshwater shrimp Caridina multidentata Stimpson 1860, a popular addition to freshwater aquaria due to its reputation for consuming algae, though in reality it is unable to survive on a diet of algae alone. Formerly referred to as C. japonica De Man 1892 (that name is now regarded as a junior synonym of C. multidentata) and also known as the Amano shrimp. Exhibits an amphidromous life cycle in nature and is thus difficult to breed in captivity, though it has been achieved.
carbonate hardness
Measure of the alkalinity of water as dictated by the presence of bicarbonate and carbonate ions. Usually expressed as parts per million, milligrams per litre, or degrees (dKH) of which 1 dKH corresponds to 17.848 ppm. Sometimes used a synonym for, but not equivalent to, temporary hardness.
