Aquariums are self-contained arrangements for holding aquatic animals and plants in captivity that have either been compactly supported by rafts or by some other form of support since the inception of the aquarium trade. An aquarium is a fish tank of any size with at least thiet ke ho nuoi ca rong one side displaying and housing live aquatic organisms or plants. Aquariums are used to keep fish, amphibians, invertebrates, reptiles, and some aquatic plants, including ferns. The water conditions in an aquarium are usually a mixture of salt, lighting, filtration, and aeration.
There are several different types of aquariums, ranging from very small aquariums used for laboratory studies to aquariums that are extremely large with many species of fish in them. Small fish tanks are usually called saltwater aquariums and can be built from plastic, wood, or concrete. A fish tank is more likely to be a freshwater aquarium with fish that are very hardy and that do not need much attention. Large aquariums or “reef” tanks are usually constructed of fiber glass, concrete, or polyethylene and can house up to thousands of fish. Both small and large aquariums are available in a variety of sizes.
Glass aquariums are one of the most widely used aquarium types. It is important to make sure that aquariums that are manufactured using polished plate glass do not contain lead. These are manufactured in a wide variety of shapes and colours to suit various home aquarium needs and there are some coloured glass aquariums that are widely used in fish tanks.
Fiber glass aquariums are widely used in fish tanks and there are a number of reasons for this. Firstly, these aquariums are widely used because they require very little maintenance and cleaning. Secondly, the large surface area of these aquariums allows for a higher density of photosynthesis which results in greater levels of oxygen in the water. Finally, since the colour of fibre glass is so vibrant and the refractive surface is such that light can pass through it easily, these types of aquariums are used as reflecting aquariums.
Some people prefer the use of aquariums that are made out of metal alloys. These include chrome-plated aquariums. Chrome-plated glass aquariums are available in a wide range of shapes and colours, are easy to clean and maintain and they do not absorb or produce waste. Metal aquariums, including gold-plated aquariums, are widely used in fish tanks because they are very durable and easy to clean.
There are several types of aquarium pumps that are used in an aquarium. The most commonly used aquarium pump is the air pumps that use air pressure to force water into an aquarium. Underwater aquarium pumps are also used in some cases but their task is not that significant in an aquarium. Lastly, there are submersible pumps that are designed to be able to move liquids or gaseous contents from the aquarium to another vessel. Finally, some aquariums may also employ the use of surface pumps which can be positioned on the outside of an aquarium to transport water from it into the aquarium.
