The beginner hobbyist to the needs of a variety of problems when starting a new tank. The misery of the home aquarium often begin with a lack of understanding of exactly what will happen in the first six weeks the tank is active. Without knowing which processes occur invisibly in the aquarium, many begin to overload the aquarium with fish and the immediate sense of their new pets to death by their own excrement. The fish actually create most of the toxins that kill! Often, the other lethal substances resulting from the excessive power that promotes putrefaction and decomposition. The new aquarium, ammonia is produced by fish and decomposition processes. You can quickly build to toxic levels. If the pH is acidic (below 7.0) the toxicity of ammonia is usually minimal, even in what could be considered high concentrations. But it is rapidly fatal when the pH rises above 7.0 reading. The higher the pH, ammonia is the most dangerous, even in small concentrations.As over time, even in a sterile environment, the good bacteria that specialize in the use of ammonia as an energy source establishing a foothold . Over time, appropriate populations to develop as fast as ammonia is produced. They produce nitrite as a byproduct. Nitrite is not related to water pH or other property. As you increase the level of nitrite, which is so deadly to fish in water conditions. Once again, nature has provided a bacterial strain which will soon remove nitrite, Nitrobacter. The specialized bacterial strains used for nitrite to nitrate of energy and create the final step.Nitrate is a good plant food, but otherwise is not removed by standard processes in the aquarium. It builds steadily to levels that eventually become harmful to fish. There is really no safe way to remove except by dilution. The water level change is the most effective method for eliminating high nitrate levels in wastewater. Of fresh tap water replacement substitution generally has a low or nonexistent. When water is added to replace material used aquarium water, the total amount of nitrate reduction and control of all this simple system method.The depends heavily on a strong and vibrant people of two different strains of bacteria (Nitrosomonas and Nitrobacter) do their job. There are also a variety of other bacteria that constantly at work in the degraded components of the waste is the natural process of decomposition. Much of this waste disposal is the production of ammonia. At first, no bacteria of all kinds, for starters, who were killed by floods, chemical companies in the supply of potable water for human consumption. Selection of strains quickly populate a start, but if the invisible world of bacteria, ammonia and nitrite reducers are relatively slow to replicate. There are many other species that much faster to use an appropriate niche and can Nitrosomonas and / or hard nitrobacter thriving.It ten days in a perfect environment to begin a slow bacteria that live in less ammonia in the billions in thousands of millions of peers necessary to remove ammonia, when it occurs. The bacteria that reduce nitrate to nitrite is even slower to replicate. It has the disadvantage that further hampered when ammonia is present too. Once the ammonia removing bacteria are sufficiently numerous to immediately exclude ammonia, then these weaker tribes begin to grow, while still three weeks to go high enough densities to eliminate nitrite as the immediate increase of well.Biological the bacterial filterThe over a very brief summary of the nitrogen cycle, not exhaustive, but the time of the combs of the bacterial population are important. It is far behind many other kinds of bacteria all fighting for space and the same factors that led to the concept of bacterial multiplication of biological filter. While criticism of the strain of bacteria that actually do the work of removing ammonia, classically defined as Nitrosomonas, and some argue that the bacteria do the work. In recent decades, certified pure strains of both Nitrosomonas and Nitrobacter are very isolated and cultured successfully. Even before this development, was long the feeling that if added to bacteria in the aquarium immediately, would help reduce the time needed for the population size to obtain and maintain concentration levels in real lower.In many very
