How to grow coral reef in a saltwater aquarium

The aquarium except marine fish are also produced and corals called reef marine aquarium. Fast-growing corals – usually of the genus Montipora, Acropora, Pocillopora and grow in the aquarium polyp for polyp until until grows a micro-reef.

Light for corals

The word “micro-reef” very often means just a small marine reef aquarium. Coral planting in artificial conditions requires intense lighting, which is rather expensive. Therefore, the smaller the size of aquarium, the less need for coverage, the cheaper it costs.

The need for intensive lighting because the light having the wavelength required for photosynthesis, passing through the water, fades with increasing depth. For illumination with a sufficient intensity of a small light bulb aquarium requires lower power than for lighting large. Besides that they consume less electricity they are also cheaper. Another their advantage is that they are less likely to heat the water. When the aquarium light should know that excessive light is as harmful to corals as weak.

Sea current in the aquarium

A saltwater aquarium requires water circulation. Motion credif places natural growth of coral reefs is very strong. Currents, tides provide a powerful turbulent motion of sea water, which cleanses the mucus from corals, sediments and rock fragments. At the same time it provides the coral with nutrients and oxygen. Therefore, the circulation of water in marine aquariums is essential. Unfortunately, you know it’s not all aquarists. Continue reading

Marine aquarium – bonding, Assembly

The first work – bonding of sump

The Assembly of the aquarium I started with SAMP. Wanted to kill not just two but several birds with one stone. First, saving money, as the volume of cans was not small, and making the most of your own hands, you can save additional money on high quality equipment and aquatic organisms. Secondly, I wanted to check if I am able to do everything myself. Thirdly, and if I can, then: how will be glued is large and heavy aquarium. This should be checked. So took the glass thickness 8 mm – for the sake of experiment.

Looking glass led to the website of Crystal that cut glass on the laser machine and cut the edge. But the most interesting is the price, it was similar to an ordinary glass cutter. In General, called the office, learned what they need to know for the order, I printed your schematic and on the way to work drove to their office. Custom designed for 40 minutes we discussed all the details thoroughly, talked on related topics. Issue price turned out 2 300 – 2 400 RUB (or rather not remember). After 4 days I called and was told that you can take the glass. Stunned! Everything was Packed in thick cardboard, and if packable 2-3 leaves, all padded with additional cardboard. Sizes are met perfectly…

Buy aquarium sealant and masking tape took place without problems in the near Chkalovsk. And then began the most interesting – we had all the mess and neatly glued together. Wanted the clearances were exactly 1 mm. this value was calculated from all the walls and internal partitions. Two nights was meditating on improvised material – it was necessary to collect a frame (frame), which would allow appending to withstand the required geometry. Continue reading

Why in the Black sea has become a little fish?

Much worse than with the anchovy and sprats. is the case with the number of predatory fish in the Black sea. In the 1980-1990-ies completely disappeared the population of palamidi, tuna and mackerel. According to the hypothesis of the biologist Y. I. Sorokin from Noumea, on the annual migration paths of tuna and mackerel from the Marmara to the Black sea is irresistible “chemical barrier” is a giant city of Istanbul, all the waste of life in the city with a million residents flows directly into the waters of the Bosphorus. Not only Istanbul, but also all other Turkish seaside towns do not have sewage treatment facilities, resulting in pollution of the Black sea domestic and industrial wastewater.

At least 170 million people are living in all black sea countries, a tangible part of their waste of life and activity is in the Black sea.

Sewage of coastal cities, after cleaning, bring in the sea, it is harmless, even useful minerals that promote rapid plant growth. The trouble is that at the end of the twentieth century these nutrient mineral salts got into the Black sea too much, putting it on the brink of environmental catastrophe. Overfeeding marine ecosystems mineral salts is called eutrophication. The result of this, it is possible to observe on primarycontent sea of slime – filamentous unicellular green algae colonial green Alga, generously fueled by domestic sewage Anapa. The day the simplest tangle of seaweed balls almost doubled in size. In July in shallow water from Anapa to Blagoveschenskaya, grew a huge mass of seaweed balls, and reached 7500 tons! Unicellular algae kladofora prevents the growth of sea grass (eelgrass), green underwater meadows of eelgrass once covered all the sandy shallows. Balls unicellular colonial green Alga shade leaves of eelgrass, entangle and strangle its growth. The eelgrass meadow is the most beautiful underwater scenery and most lively habitat for various species of marine animals – crabs crustaceans-hermit crabs, seahorses, sea eagle, shrimp, etc. Continue reading
