A colorless or white crystalline compound, CaCO, occurring naturally as chalk, limestone, marble, and other forms and used in a wide variety of manufactured products including commercial chalk, medicines, and dentifrices
Scale that forms from calcium compounds when pool water is too alkaline, calcium hardness is too high or Total Alkalinity is too high These hard deposits accumulate on pool surfaces and equipment
Chemical compound with the formula CaCO3, a k a chalk Tends to raise pH; food grade calcium carbonate may be added in small amounts to brewing water if the pH is too low
is found in nature in the form of calcite, chalk and limestone It can be used in the production of cement, houses, pools, and various durable structures
(CaCO3)- Scale that forms from calcium compounds when pool water is too alkaline, calcium hardness is too high or total alkalinity is too high These hard deposits accumulate on pool surfaces and equipment
a molecule consisting of calcium, carbon and oxygen secreted by corals to their skeleton It is also secreted by mollusks to form their protective shells
CaCO3, one of the most stable, common, AND widely dispersed materials It occurs in oyster shells, chalk, limestone, marble and travertine, and is a major cause of boiler scale when hard water is used in heating systems It can be mined from natural surface deposits or precipitated (made synthetically) by reaction of calcium chloride and sodium carbonate in water solution, or by passing carbon dioxide through a suspension of hydrated lime (Ca(OH)2) in water It is soluble in acids with evolution of carbon dioxide [2]
A chemical combination of calcium, carbon, and oxygen the main constituent of limestone It forms a tenacious scale in water-handling facilities and is a cause of water hardness Chemical symbol is CaCO3
` White rhombohedrons or a white powder; occurs naturally as calcite; used in paint manufacture, as a dentrifice, as an anti-caking medium to table salt, and in the manufacture of rubber tires Chemical formula CaCO3
Crystalline compounds formed in swimming pool and spa water when the calcium, pH and total alkalinity levels are too high Once formed, the crystals adhere to the plumbing, equipment, pool walls and bottom These crystals are better known as scale
(CaCO3) The principal hardness and scale-causing compound in water A white precipitate that forms in water lines, water heaters, and boilers in hard water areas; also known as scale Also the principal chemical composition of Tufa, a calcareous and siliceous rock deposit of springs, lakes, or ground water
crystalline deposits that can form on all under water surfaces, if the water is excessively high in calcium hardness High pH and high total alkalinity can worsen the problem
