In J. Charles Delbeek's article Your First Reef Aquarium, [2] he states, The use of live rock immediately introduces into the aquarium numerous algae, bacteria and small invertebrates all of which contribute to the overall quality of the aquarium water. Live rock has just as much, if not more, surface area for bacteria than a trickle filter.
Calcarenite is a type of limestone that is composed predominantly, more than 50 percent, of detrital (transported) sand-size (0.0625 to 2 mm in diameter), carbonate grains. The grains consist of sand-size grains of either corals , shells , ooids , intraclasts , pellets , fragments of older limestones and dolomites , other carbonate grains, or ...
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. It occurs widely, often in association with limestone and evaporites , though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 ...
Limestone is the chief form of calcium carbonate rock, which is dissolved by water that contains carbon dioxide, forming a calcium bicarbonate solution in caverns. [5] The partial pressure of carbon dioxide in the water must be greater than the partial pressure of carbon dioxide in the cave chamber for conventional stalagmite growth.
Limestone is a geological rock formed primarily from calcium carbonate and in water. It is produced principally during periods when there is a high proportion of carbon dioxide in the atmosphere . It varies greatly in its hardness and in the materials included in it so its commercial uses vary.
Pellets and a brachiopod shell visible in a limestone thin-section; Bird Spring Formation (Carboniferous) of southern Nevada. Pellets are small spherical to ovoid or rod-shaped grains that are common component of many limestones. They are typically 0.03 to 0.3 mm long and composed of carbonate mud . Their most common size is 0.04 to 0.08 mm ...
