When the fish, plants and foods in the aquarium a process known as nitrification occurs, it is referred to as the nitrogen cycle. This is not unique to aquariums; nitrification will occur in any body of water, or soil, where bacterial action decomposes decomposing organic matter and converts it into ammonia. Ammonia compounds are then oxidized into nitrites and nitrates.
These nitrifying bacteria can be described as beneficial or good bacteria, without the aquarium inhabitants could not survive. The process begins with the heterotrophic bacteria consume fish waste, decaying vegetation, and uneaten food, and their conversion into ammonia.
Ammonia (NH3) is a colorless, pungent, suffocating gas, a compound of nitrogen and hydrogen, and it is very soluble in water. The majority of waste produced by fish is in the form of ammonia, most of which are secreted by the gills. The rest excreted in faeces, is transformed into ammonia by heterotrophic bacteria.
Ammonia is extremely toxic to fish and must be removed or broken. Visual signs of fish to succumb to this toxicity include:
The blast on the surface
Cloudy eyes
Fins frayed
Indifferent behavior
Increased production of mucus
Possible internal and external bleeding (if extreme toxicity exists)
Because of the toxic effects of high levels of ammonia, it may be dead, even after ammonia levels are under control. Small fish have a greater surface Gill on a larger fish, and are therefore more susceptible to toxic ammonia.
Water changes are the best way to solve the problems of ammonia. You must make partial changes of water more than a few days at low levels. Resin-based media or zeolites are available at stores and water are very useful to the elimination of various substances freshwater aquariums, including ammonia.
Moving to a fish tank security will terminate the absorption of ammonia immediately, and they can be returned to the main tank when the ammonia levels back to zero. If you have a high pH level, you can try to reduce the nearest 7.0, which will also reduce the toxicity of ammonia.
The pH is an important factor in controlling many chemical balances, including ammonia and ammonium are included. pH is logarithmic, which is the factor controlling the presence of ammonia or ammonium.
Ammonium (NH4) is less toxic than ammonia, and is formed when ammonia reacts with acids, so if ammonia is present in the aquarium, and the pH of the water is acidic, then Ammonia is ammonium.
As pH increases, so does the toxicity of ammonia, ie a pH increased from 7.0 to 8.0 is ten times more in the hydroxyl ion (and a decrease the concentration of hydrogen) and, finally, a tenfold increase the toxicity of ammonia.
It is therefore necessary to test for ammonia before increasing significantly the pH. Ammonia tests show a zero reading when the nitrogen cycle is working well, and Nitrosomonas bacteria consume ammonia and convert it to nitrite.
Nitrite (NO2) is also toxic to fish if not eliminated or converted to nitrate in the nitrogen cycle. 1ppm levels above must be removed by making important changes of water. This should be done on a daily basis for a number of days, tests regularly, until the level of nitrite reduced to zero.
Moving to a fish tank security will terminate the absorption of nitrites immediately. They can then be returned to your main tank at nitrite reads zero. Symptoms of toxicity, nitrite:
Apathy
The blast on the surface
Blood and turning brown gills
Nitrite is also dependent on pH, and if the pH drops below 6.5, when nitrite is present in water, nitrite convert to nitrous acid. This too is highly toxic to fish.
Nitrate (NO3) is the final product of the nitrogen cycle, and is relatively nontoxic, although high concentrations can still be a problem. Nitrite is converted to nitrate by bacteria Nitrobacter, and the presence of nitrates in a freshwater aquarium indicates that the process of nitrification of work.
Some species are more tolerant than others nitrates, but such an approach would be to maintain levels below 50 ppm (mg / l). Some symptoms of the toxicity of nitrate would be:
Poor general health
Slow growth
Poor color
Less tolerance to the disease
Nitrate is an essential source of food for plants and algae, if you encourage the growth of healthy plants in your aquarium, the levels will be reduced. Otherwise, if the tests show high levels, it would indicate a partial change of water is necessary.
Regular partial water changes when carried out during maintenance generally retain control anyway. Ammonia and nitrite levels tend to be at their highest level in the first 4 to 6 weeks of a new aquarium. This is generally known as new tank syndrome.
Hydrogen sulfide (H2S) is a highly toxic gas that smells like rotten eggs, even in small concentrations, it can cause rapid death. It is produced during the decomposition of organic matter that contains sulfur, and the action of dilute acid on sulfides (acid aquariums being at risk).
The usual cause of the aquarium is probably one of negligence, not the substrate keeping clean dirt and debris, thus enabling the deteriorating building. A first indication of this problem may be a sudden bloom of algae.
The toxic gas affects fish by linking the iron in hemoglobin blood, which blocks the absorption of oxygen, which causes symptoms, which include:
Respiratory problems
The blast on the surface
Unusual coloring gills
Aquarium maintenance, make sure to clean all the debris of the substrate, avoids the problem.
