Natural Aquarium World: Natural Aquarium World Vol. About this product. Make an offer: Appropriate handling of the nitrogen cycle , along with supplying an adequately balanced food supply and considered biological loading, is enough to keep these other nutrient cycles in approximate equilibrium.
An aquarium must be maintained regularly to ensure that the fish are kept healthy. Daily maintenance consists of checking the fish for signs of stress and disease.
A good habit is to remove the water being replaced by "vacuuming" the gravel with suitable implements, as this will eliminate uneaten foods and other residues that settle on the substrate. Tap water from those areas must be treated with a suitable water conditioner, such as a product which removes chlorine and chloramine and neutralizes any heavy metals present. The water conditions must be checked both in the tank and in the replacement water, to make sure they are suitable for the species.
The solute content of water is perhaps the most important aspect of water conditions, as total dissolved solids and other constituents dramatically impact basic water chemistry, and therefore how organisms interact with their environment. Salt content, or salinity , is the most basic measure of water conditions. Rarely, higher salt concentrations are maintained in specialized tanks for raising brine organisms. Saltwater is typically alkaline, while the pH alkalinity or acidicity of fresh water varies more.
Hardness measures overall dissolved mineral content; hard or soft water may be preferred. Hard water is usually alkaline, while soft water is usually neutral to acidic. Home aquarists typically use tap water supplied through their local water supply network to fill their tanks.
Straight tap water cannot be used in localities that pipe chlorinated water. In the past, it was possible to "condition" the water by simply letting the water stand for a day or two, which allows the chlorine time to dissipate.
Additives formulated to remove chlorine or chloramine are often all that is needed to make the water ready for aquarium use. Brackish or saltwater aquaria require the addition of a commercially available mixture of salts and other minerals.
Some aquarists modify water's alkalinity, hardness, or dissolved content of organics and gases, before adding it to their aquaria.
This can be accomplished by additives, such as sodium bicarbonate, to raise pH. In contrast, public aquaria with large water needs often locate themselves near a natural water source such as a river, lake, or ocean to reduce the level of treatment. Some hobbyists use an algae scrubber to filter the water naturally. Water temperature determines the two most basic aquarium classifications: Cold water aquaria are for fish that are better suited to a cooler environment.
More important than the range is consistency; most organisms are not accustomed to sudden changes in temperatures, which can cause shock and lead to disease.
Water movement can also be important in simulating a natural ecosystem. Aquarists may prefer anything from still water up to swift currents , depending on the aquarium's inhabitants.
Water movement can be controlled via aeration from air pumps, powerheads, and careful design of internal water flow such as location of filtration system points of inflow and outflow.
Of primary concern to the aquarist is management of the waste produced by an aquarium's inhabitants. Fish, invertebrates, fungi , and some bacteria excrete nitrogen waste in the form of ammonia which converts to ammonium , in water and must then either pass through the nitrogen cycle or be removed by passing through zeolite.
Nitrogen waste products become toxic to fish and other aquarium inhabitants at high concentrations. 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.
A well-balanced tank contains organisms that are able to metabolize the waste products of other aquarium residents. This process is known in the aquarium hobby as the nitrogen cycle. Bacteria known as nitrifiers genus Nitrosomonas metabolize nitrogen waste.
Nitrifying bacteria capture ammonia from the water and metabolize it to produce nitrite. Another type of bacteria genus Nitrospira converts nitrite into nitrate , a less toxic substance. Nitrobacter bacteria were previously believed to fill this role. While biologically they could theoretically fill the same niche as Nitrospira , it has recently been found that Nitrobacter are not present in detectable levels in established aquaria, while Nitrospira are plentiful.
In addition to bacteria, aquatic plants also eliminate nitrogen waste by metabolizing ammonia and nitrate.
When plants metabolize nitrogen compounds, they remove nitrogen from the water by using it to build biomass that decays more slowly than ammonia-driven plankton already dissolved in the water. What hobbyists call the nitrogen cycle is only a portion of the complete cycle: The aquarium keeper must remove water once nitrate concentrations grow, or remove plants which have grown from the nitrates.
Hobbyist aquaria often do not have sufficient bacteria populations to adequately denitrify waste. This problem is most often addressed through two filtration solutions: Activated carbon filters absorb nitrogen compounds and other toxins , while biological filters provide a medium designed to enhance bacterial colonization.
Activated carbon and other substances, such as ammonia absorbing resins, stop working when their pores fill, so these components have to be replaced regularly. New aquaria often have problems associated with the nitrogen cycle due to insufficient beneficial bacteria. There are three basic approaches to this: In a fishless cycle , small amounts of ammonia are added to an unpopulated tank to feed the bacteria. During this process, ammonia , nitrite , and nitrate levels are tested to monitor progress.
The "silent" cycle is basically nothing more than densely stocking the aquarium with fast-growing aquatic plants and relying on them to consume the nitrogen , allowing the necessary bacterial populations time to develop. According to anecdotal reports, the plants can consume nitrogenous waste so efficiently that ammonia and nitrite level spikes seen in more traditional cycling methods are greatly reduced or disappear.
This method is usually done with a small starter population of hardier fish which can survive the ammonia and nitrite spikes, whether they are intended to be permanent residents or to be traded out later for the desired occupants.
The largest bacterial populations are found in the filter, where is high water flow and plentiful surface available for their growth, so effective and efficient filtration is vital. Sometimes, a vigorous cleaning of the filter is enough to seriously disturb the biological balance of an aquarium. Therefore, it is recommended to rinse mechanical filters in an outside bucket of aquarium water to dislodge organic materials that contribute to nitrate problems, while preserving bacteria populations.
Another safe practice consists of cleaning only half of the filter media during each service, or using two filters, only one of which is cleaned at a time.
The biological load, or bioload, is a measure of the burden placed on the aquarium ecosystem by its inhabitants. High biological loading presents a more complicated tank ecology, which in turn means that equilibrium is easier to upset. Several fundamental constraints on biological loading depend on aquarium size. The water's surface area limits oxygen intake. The bacteria population depends on the physical space they have available to colonize. Physically, only a limited size and number of plants and animals can fit into an aquarium while still providing room for movement.
Biologically, biological loading refers to the rate of biological decay in proportion to tank volume. Adding plants to an aquarium will sometimes help greatly with taking up fish waste as plant nutrients. Although an aquarium can be overloaded with fish, an excess of plants is unlikely to cause harm. Decaying plant material, such as decaying plant leaves, can add these nutrients back into the aquarium if not promptly removed. The bioload is processed by the aquarium's biofilter filtration system.
Limiting factors include the oxygen availability and filtration processing. Aquarists have rules of thumb to estimate the number of fish that can be kept in an aquarium. The examples below are for small freshwater fish; larger freshwater fishes and most marine fishes need much more generous allowances. Experienced aquarists warn against applying these rules too strictly because they do not consider other important issues such as growth rate, activity level, social behaviour, filtration capacity, total biomass of plant life, and so on.
This is because fish of different sizes produce quite differing amounts of waste. Establishing maximum capacity is often a matter of slowly adding fish and monitoring water quality over time, following a trial and error approach. One variable is differences between fish. Smaller fish consume more oxygen per gram of body weight than larger fish. Labyrinth fish can breathe atmospheric oxygen and do not need as much surface area however, some of these fish are territorial, and do not appreciate crowding.
Barbs also require more surface area than tetras of comparable size. Oxygen exchange at the surface is an important constraint, and thus the surface area of the aquarium matters.
Some aquarists claim that a deeper aquarium holds no more fish than a shallower aquarium with the same surface area. The capacity can be improved by surface movement and water circulation such as through aeration, which not only improves oxygen exchange, but also waste decomposition rates.
Waste density is another variable. Decomposition in solution consumes oxygen. Oxygen dissolves less readily in warmer water; this is a double-edged sword since warmer temperatures make fish more active, so they consume more oxygen. For instance, predatory fish are usually not kept with small, passive species, and territorial fish are often unsuitable tankmates for shoaling species. Furthermore, fish tend to fare better if given tanks conducive to their size. That is, large fish need large tanks and small fish can do well in smaller tanks.
Lastly, the tank can become overcrowded without being overstocked. In other words, the aquarium can be suitable with regard to filtration capacity, oxygen load, and water, yet still be so crowded that the inhabitants are uncomfortable. For planted freshwater aquariums, it is also important to maintain a balance between the duration and quality of light, the amount of plants, CO 2 and nutrients. For a given amount of light, if there is insufficient number of plants or insufficient CO 2 to support the growth of those plants, so as to consume all the nutrients in the tank, the result would be algae growth.
While there are fishes and invertebrates that could be introduced in the tank to clean up this algae, the ideal solution would be to find the optimal balance between the above-mentioned factors. Supplemental CO 2 can be provided,  whose quantity has to be carefully regulated, as too much CO 2 may harm the fishes. From the outdoor ponds and glass jars of antiquity, modern aquaria have evolved into a wide range of specialized systems.
Individual aquaria can vary in size from a small bowl large enough for only a single small fish, to the huge public aquaria that can simulate entire marine ecosystems. One way to classify aquaria is by salinity. Freshwater aquaria are the most popular due to their lower cost. Marine aquaria frequently feature a diverse range of invertebrates in addition to species of fish.
Subtypes exist within these types, such as the reef aquarium , a typically smaller marine aquarium that houses coral. Another classification is by temperature range. Many aquarists choose a tropical aquarium because tropical fish tend to be more colorful. Aquaria may be grouped by their species selection. The community tank is the most common today, where several non-aggressive species live peacefully.
In these aquaria, the fish, invertebrates , and plants probably do not originate from the same geographic region, but tolerate similar water conditions. Aggressive tanks, in contrast, house a limited number of species that can be aggressive toward other fish, or are able to withstand aggression well.
Most marine tanks and tanks housing cichlids have to take the aggressiveness of the desired species into account when stocking. Specimen tanks usually only house one fish species, along with plants, perhaps ones found in the fishes' natural environment and decorations simulating a natural ecosystem.
This type is useful for fish that cannot coexist with other fish, such as the electric eel , as an extreme example. Some tanks of this sort are used simply to house adults for breeding. Ecotype, ecotope, or biotope aquaria is another type based on species selection. In it, an aquarist attempts to simulate a specific natural ecosystem, assembling fish, invertebrate species, plants, decorations and water conditions all found in that ecosystem.
In addition, the shadow it casted required additional lighting to be added that made the whole design less attractive. Bottom line is that building a tree can work; but it can also not work when it is overly designed.. Do not get me wrong, it was an excellent scape with a lot to learn fromI am simply critiquing to find the line between good and great.
I had an enjoyable time at the event.
