Artificial seawater (abbreviated ASW) is a mixture of dissolved mineral salts (and sometimes vitamins) that simulates seawater. Artificial seawater is primarily used in marine biology and in marine and reef aquaria , and allows the easy preparation of media appropriate for marine organisms (including algae , bacteria , plants and animals ).
Saltwater aquaponics (also known as marine aquaponics) is a combination of plant cultivation and fish rearing (also called aquaculture), systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater. In some instances, this may be diluted saltwater.
Marine aquariums can range in volume from less than 80 litres, (< 20 US gal) to over 1,200 litres (300 US gal). Small volumes are more difficult to maintain due to the more rapid changes in water chemistry. The majority of saltwater aquariums are between 160 and 400 litres (40 and 100 US gal). Nano reef aquarium maintained at home
An aquarium may have freshwater (salinity below 500 parts per million), simulating a lake or river environment; brackish water (a salt level of 500 to 30,000 PPM), simulating environments lying between fresh and salt, such as estuaries; and salt water or seawater (a salt level of 30,000 to 40,000 PPM), simulating an ocean environment. Rarely ...
Protein skimming removes certain organic compounds, including proteins and amino acids found in food particles and fish waste, by using the polarity of the protein itself. . Due to their intrinsic charge, water-borne proteins are either repelled or attracted by the air–water interface and these molecules can be described as hydrophobic (such as fats or oils) or hydrophilic (such as salt ...
Bear in mind that a saltwater aquarium is more expensive and difficult to set up and maintain than freshwater even if you chose one of the best fish tanks. Some of the fish, too, can fetch eye ...
Some freshwater species (and the blacktip shark, a marine species) are hardy enough or survive better in brackish water, such as Polypterus bichir, certain loaches, Danio rerio, all kinds of mollies but especially the Yucatán molly, and some gobies. All can tolerate the same amount of salt in aquaria, but should be acclimated slowly.
Reactors may be used in elaborate freshwater and brackish aquariums where freshwater clams and other invertebrates need a constant supply of calcium. Calcium reactor. In marine and reef aquariums, a calcium reactor dissolves a calcium carbonate media in order to balance alkalinity and introduce other trace elements.
