What is the aquarium? This is the most common type of vivarium 1. Typically the aquarium is made of glass or transparent plastic. With fish and plants, invertebrates, molluscs and plants, the aquarist creates a private area of the underwater world and supports its living state.
Previously, under the aquarium knew the dishes for storage of various liquid preparations. In a vessel put the various bottles and kegs which were stored in water. In England the term “aquarium” refers to the dishes for the maintenance of aquatic plants, but not animals. The modern concept of aquariums has been formed in the XIX century.
The General public, the aquarium was presented in 1851 at the world exhibition in London, and the term “aquarium” was proposed by the English naturalist Philip Henry Gosse in his book “the Naturalist on the coast of Devonshire”. The book enjoyed great popularity. With the release of his book “the Aquarium: Wonders of the deep sea” it has become fashionable to keep exotic tropical fish and other animals in the house.
The development of the aquarium over the next 100 years is primarily due to the understanding that the aquarium without adequate chemical and technical support can not provide a comfortable environment for fish and plants. Understanding biological and chemical processes occurring in the aquarium, helped to create a more complex aquarium filters,improved lighting systems, etc. Along with this decreased and the cost of equipment. Adequate price on aquarium equipment has made this hobby available to the majority of the population. Continue reading
Most of the fish for reproduction lay eggs, but there are a few species that give birth are ready fry. This, for example, the great white shark.
Mudskipper is a fish which spends the majority of his time out of the water and can “walk” on their own fins. In the gills the jumpers for a long time kept a small supply of water. They can also breathe through the pores of its wet skin.

In recent years it has become fashionable to arrange on individual plots of various artificial reservoirs. However, few people initially is that they require fairly little maintenance. Incorrect maintenance of the pond in it there are various putrefactive processes, the dominance of algae, which causes sotsvetiye water, elevated sediment (siltation).
One of the most effective and easiest ways to prevent all these problems is the forced saturation of water with oxygen. For these purposes are used aerators for ponds. These hydraulic mechanisms are also called air compressors.
Their role cannot be overestimated, especially in winter, when the ice cap prevents both the flow of air into the water, and the removal of waste products of microorganisms and plants. But if the pond has fish, aerator for it just need. In summer, the decay of the reservoir also has a negative impact on the balance of the whole area. In addition, various unpleasant odors coming from the water, hardly conducive to proper rest on the nature.
Types of aerators for the pond
The oxygen saturation is in the process of suction air, which is uniformly mixed with the liquid and dissolves in it. They are distinguished by low productivity with significant energy consumption. Home “plus” work practices.consumer. Continue reading
