Aquariums are self-contained, self-watering environments where live plants and animals are contained together in a relatively confined space. Aquariums have been around since the 1950s but they have become more popular over the last few years due to their low maintenance and value for money. An aquarium is usually a closed-circuit system containing at least one glass side where live aquatic animals or plants are housed and shown.
Many people now understand that aquariums are more than just a fish tank or water filled with tropical plants. Aquarium enthusiasts now use aquariums to house multiple animals, invertebrates, reptiles, amphibians, including turtles, and other aquatic plants, including ferns. Most aquariums are made from a combination of metal, wood, acrylic, plastic, and other materials thiet ke thi cong ho ca rong. The most commonly used materials for making aquariums are glass, fiberglass, resin, acrylic, polycarbonate, copper, and glass-ceramic.
There are two basic types of aquariums, freshwater aquariums and saltwater aquariums. In a freshwater aquarium, all of the water and aquarium equipment is housed in a closed circuit system that is mainly controlled by an automatic pump. The same is true for a marine aquarium, which uses similar technology to an air conditioner, but instead circulates the water through a special filter system.
Another type of aquariums are the plant tanks or the fish tanks, made primarily of fiber glass. The fish are placed inside the tank with the water circulating around the bottom of the tank and the plants on the top. The tank can either be suspended over the floor of the room or on a shelf with a net or cover so the plants stay well above the water line. Plastic plants are also widely used because they do not require any artificial lighting and cooling.
Marine aquariums are very popular, mostly for decorative purposes. The biggest advantage of marine tanks is the ease with which they can be cleaned. All that is required are simple procedures like replacing the top film, regular cleaning of the filters, occasional pumping of water, and general cleaning, and you can keep your freshwater tank looking like new for years. A lot of people keep freshwater aquariums for the sole purpose of breeding ornamental fish species such as plecos and tangs. These species can be very expensive to buy and keeping them in small aquariums allows them to be properly cared for. These species also tend to be very sensitive to changes in their environment, so small aquariums allow them to grow and flourish while they are under close observation.
Freshwater aquariums are usually found in public aquariums, where the owner assumes responsibility for the maintenance of the environment. Many people prefer to keep aquariums since they can be put together very quickly, unlike the pre-assembled units that must be assembled by an expert. It can take just a few hours to build a small aquatic tank, whereas larger freshwater habitats can take days to construct if you have a dedicated team of aquarium technicians working on it. For anyone with a basic knowledge of fish and freshwater aquariums, building an aquarium can be a very satisfying experience.
