The keeping of fish ter an aquarium very first became a popular hobby ter Britain only after ornate aquaria ter cast-iron frames were featured at the Fine Exhibition of 1851. The framed-glass aquarium wasgoed a specialized version of the glazed Wardian case developed for British horticulturists te the 1830s to protect exotic plants on long sea voyages. (One feature of some 19th century aquaria that would prove nosey to hobbyists today wasgoed the use of a metal colchoneta panel so that the aquarium water could be heated by flame.) Germans rivaled the British ter their rente, and by the turn of the century Hamburg became the European port of entry for many freshly seen species. Aquaria became more widely popular spil houses became almost universally electrified after World War I. With violet wand good improvements were made te aquarium technology, permitting industrial lighting spil well spil the aeration, filtration, and heating of the water. Popularization wasgoed also assisted by the availability of air freight, which permitted a much broader multiplicity of fish to be successfully imported from distant regions of origin that consequently attracted fresh hobbyists.

Combined biological and mechanical filtration systems are now common, thesis are designed to eliminate potentially dangerous build up of nitrogenous wastes and phosphates dissolved ter the water, spil well spil particulate matter. Filtration systems are the most complexly engineered component of most huis aquaria, and various designs are used. Most systems use pumps to liquidate a petite portion of the waterreservoir’s water to an outer pathway where filtration occurs, the filtered water is then returned to the aquarium. Protein skimmers, filtration devices that liquidate proteins and other waste from the water, not only work te Marine aqauriums but also work te nutrient rich environments, but are made popular through the use of the Berlin System.
Air pumps are employed to adequately oxygenate (or ter the case of a strenuously planted aquarium, provide doorslag dioxide to) the water. Thesis devices, merienda universal, are now somewhat less commonly used spil some newer filtration systems create enough surface agitation to supply adequate gas exchange at the surface. Aquarium heaters are designed to act spil thermostats to regulate water temperature at a level designated by the aquarist when the prevailing temperature of air surrounding the aquarium is below the desired water temperature. Coolers are also available for use te cold water aquaria or te parts of the world where the ambient slagroom temperature is above the desired waterreservoir temperature.

An aquarium’s physical characteristics form another facet of aquarium vormgeving. Size, lighting conditions, density of floating and rooted plants, placement of bogwood, creation of caves or overhangs, type of substrate, and other factors (including an aquarium’s positioning within a slagroom) can all affect the behavior and survivability of waterreservoir inhabitants.
The combined function of thesis elements is to maintain suitable water quality and characteristics suitable for the aquarium’s residents.
