Aquarium filter. Air-driven corner filter. Aquarium filters are critical components of both freshwater and marine aquaria. [1] [2] [3] Aquarium filters remove physical and soluble chemical waste products from aquaria, simplifying maintenance. Furthermore, aquarium filters are necessary to support life as aquaria are relatively small, closed ...
When fish are put into an aquarium, waste can quickly reach toxic concentrations in the enclosed environment unless the tank is cycled to remove waste. [page needed] The process. A well-balanced tank contains organisms that are able to metabolize the waste products of other aquarium residents, recreating a portion of the nitrogen cycle.
Recirculating aquaculture system. Recirculating aquaculture systems ( RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a ...
Ammonia poisoning is a common fish disease in new aquariums, especially when immediately stocked to full capacity. Ideally, the level of ammonia (NH 3) and ammonium compounds (i.e. those containing NH 4+) in fish tanks should be zero. Although trace amounts are generally harmless, they can still lead to problems over time. [1]
Septic tank. A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater ( sewage) flows for basic sewage treatment. [2] Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). [2]
A marine aquarium is an aquarium that keeps marine plants and animals in a contained environment. Marine aquaria are further subdivided by hobbyists into fish only ( FO ), fish only with live rock ( FOWLR ), and reef aquaria. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical ...
There are many causes of fish kill, but oxygen depletion is the most common cause. The term fish kill, known also as fish die-off, refers to a localized die-off of fish populations which may also be associated with more generalized mortality of aquatic life. [1] [2] The most common cause is reduced oxygen in the water, which in turn may be due ...
Solid waste can be recycled in fish meal plants or it can be treated as municipal waste. Liquid wastes: include bloodwater and brine from drained storage tanks, and water discharges from washing and cleaning. This waste may need holding temporarily, and should be disposed of without damage to the environment.
