Clean water is essential for the biological balance in the garden pond. Water quality has a direct impact on the growth and reproduction of plants, the growth of microorganisms and fish health. The water should contain all the necessary elements that are important for the proper flow of biological and chemical processes. If all the indicators are normal, and livelihoods at the micro-level optimal, then Your garden pond is established biological balance. For many, garden ponds, where, as a rule, the ratio of fish to water volume is very large, beautiful and successful solution is to install the filter. In the garden pond is one fish about four times less water compared to the reservoir in wildlife. The natural balance is disturbed quickly also because of the waste products of the inhabitants of the lake. This is especially true for koi. On the one hand, the water in the pond through the filter is maintained in a clean condition, and, on the other hand, the filter will take care of proper water circulation, which in turn will provide additional supply of the required amount of oxygen. Pressure filter provides both mechanical and biological treatment. Continue reading
The greatest length of the Black sea from North to South — 580 km and a maximum depth of 2210 m, the average — 1240 m. the salinity of the water is approximately 18 ppm. The depth increases pretty quickly. Over a sloping beach near Evpatoria, Feodosia. On the South coast, in mountain areas, the depth increases more rapidly: a few meters from the shore you have to swim (or, in the alternative, to swim along the shore). Be careful, even at a short distance from the shore can be strong currents to deal with which is not prepared person is quite difficult. But mostly this does not apply to places of mass bathing (if not to swim too far). Waters of the Black sea, as a rule, not susceptible to freezing. The average sea temperature in winter ranges from +6 to +8 degrees, in summer — from +22 to +24 degrees (can warm up to 26 degrees in a particularly hot summer). However, it is worth noting that the Black sea could throw a “surprise”: one day deep cold currents cool the coastal waters up to 12 degrees, even Continue reading
The first two weeks in the system was the rapid development of heterotrophic bacteria feeding on organic waste products of marine fishes . The result is what appear in water ammonia and ammonium, whose concentration quickly reaches a maximum. It is very unpleasant, but a natural phenomenon is called and can be detrimental to aquatic life. That’s why, to avoid the risk, tender fish species inhabit the aquarium only after a month or two after system startup of the biofilter. As nutrients in the form of ammonium in the substrate begin to develop nitrifying bacteria converts it into significantly less toxic nitrites.
At the third or fourth week, the concentration of nitrites reaches a maximum, which also, despite the decrease in ammonium concentration, it is dangerous to aquarium inhabitants. In turn, the bacteria of another species, consuming nitrites, gradually reduce their concentration, and biofilter begins to work normally. It must comply with one prerequisite – oxygen mode: the oxygen content of the water should be close to saturation. This is achieved by use of active aeration. Continue reading
