Among infectious diseases most common diseases of bacterial origin: aeromonosis and Pseudomonas.
Aeromonosis.The causative agent is aeromonad – motile gram-negative bacteria p. Aeromonas (A. hydrophila, A. sobria) related to SEM. Vibrionaceae. Hits all the main types of pond fish (carp, white Amur, carp, crucian carp). The factors contributing to the development of fish are the sharp increase in water temperature, low fatness of the fish, dense planting, poor feeding, high content of organic matter, the trauma to the fish.
Aeromonosis is acute, subacute and chronic. The acute form is observed in the spring and summer and can be accompanied by mass death of fish (70%). The disease manifests itself in the form of serous-hemorrhagic inflammation of the skin and is characterized by edema, ekzoftalm, enlarged abdomen, aresenium scales. At autopsy in the abdominal cavity detect the exudates (clear, yellowish or bloody fluid), peritonitis, hemorrhagic inflammation of the intestines, degeneration of the internal organs (increase, discoloration, foci of necrosis).

Red sea – an inland sea of the Indian ocean situated between the Arabian Peninsula and Africa. For the inner sea depth here is very high – more than 3000 meters, as this sea lies in a tectonic break. The Red sea is not no river flows (around deserts), and therefore the water is exceptionally clean.
Off the coast of Egypt water temperature even in winter does not fall below +20 degrees, and in summer rises to +27. Due to the heat evaporates much water, causing the salinity of the red sea reaches 38-42 grams of salts per liter.
In this sea are ideal conditions for underwater flora and fauna. There are about a thousand species of fish, including endemic species, and about 150 species of corals. The coral reef extends directly along the shore, and near them go to schools of fish of most unimaginable colors and shapes.
In the Northern hemisphere there’s no better scuba diving than the coast of Hurghada, Safaga, El Gouna, Sharm El Sheikh, Ein Sukhna, Marsa El Alam. Diving Safari – long trips on boats and yachts in the southern and Northern areas of the red sea. The term “Safari” means a cruise ship with multiple dives in the most interesting points of the sea’s many Islands, atolls, coral reefs and sunken ships. Continue reading
Overflow system for a saltwater aquarium is required for circulation of water between the aquarium and sump (technical capacity for filtration and the maintenance of regenerative processes of water circulated in the system). Made of high quality food-grade, chemically-resistant material, not susceptible to UV degradation.
All, both novice and experienced lovers of the marine aquarium when you install a marine aquarium one way or another faced with the problem of the choice of system overflow, and usually the choice is not too large, either the so-called “mine”, the overflow through the top of the aquarium, etc. We do not claim that spillovers are bad, not at all, fine, BUT! all these systems have a major drawback — external unattractiveness. And always a way out, as they say — next.
We have designed a overflow that allows you to organize reliable and noiseless circulation of water between the aquarium and sump, while maintaining the aesthetics of the interior of the main tank. Continue reading
