In the aquarium you read Internet forums often that the right water levels is an important prerequisite for the position of our fish are. The necessary water tests are actually imposed as a required each responsible aquarists. Discussed are a handful of different tests for pH, nitrite, nitrate and hardness, all the test kits or electronic meters for pH, conductivity, etc., are already recommended to the beginner, even if standard ornamental fish, which every hardware store or any store always in stock has care of, like.
are also denigrated the test strips to be unusable because they were too vague. The drop tests should provide an exact quantitative determination and to a fine Gradation have.
Again and again in the sequence then known as concrete values, whether in the discussions, reference is made in which water levels are referred to species databases. These are usually the pH and the hardness.
How important are the individual values for the ecosystem aquarium and its inhabitants? Apart
of toxic substances such as nitrite and heavy metals such as copper have different substances impact on the physiology of the fish or plants or the other fauna and flora such as bacteria and algae.
The pH value
The direct effect strong acidic or alkaline water on the fish affects the external corrosion the gills and skin. This is probably only at very extreme values below 4.0 or above 9, x is given. The pH of body fluids, blood, and intracellular as extracellular fluids, regulates the fishing of gills, kidney and other organs. The blood pH is regulated in the same in all vertebrates and is expected to sum thus around 7.5.
the plants I have had the experience that they are better in slightly acidic water.
bacteria, if they do not float free in the water settle in biofilms. The pH in these films is determined by the metabolism and excretion of micro-organisms and can vary within the biofilms and pH in the open water value.
Osmotic pressure
osmosis is the balance of concentrations of substances in aqueous solutions, which are separated by a semipermeable membrane. The higher the concentration difference, the stronger the osmotic pressure.
If we take the conductivity as a measure of the ion content of solutions and their difference as a measure of the osmotic pressure, so does that mean for the body of the fish following. The conductivity of blood is about 15 000 cm at uS /, to the aquarium water at about 500-1000 uS / cm. The fish takes to water that is constantly in order to reach a balance. The excretory organs such as the kidney, strive to keep the valuable materials back. Fish have an active system, so the difference in concentration to maintain. The inclusion of important substances occurs through diet and the other via the gills. Here they have include cells containing certain substances may have known the Ionozyten, that different salts are added.
The carbonate
The carbonate, acronym KH, or more precisely, the acid binding capacity (SBC), a measure of the buffering and stability of the pH value is in the water. Roughly speaking, the higher the alkalinity, the higher and more stable is also the pH value. It forms together with the amount of carbon dioxide, the main buffer system in the aquarium water.
Total hardness
GH symbol denotes the percentage of calcium and magnesium ions in water. The higher the value, the harder our water.
Most of our fish come from waters with soft water.
Toxic Stick Zoff compounds
ammonia and nitrite are intermediates in the degradation of nitrogen-containing substances. They are toxic to the fish. In a retracted aquarium with a functioning micro-fauna, they are virtually no more.
nitrate, the end product of nitrogen removal (nitrification), and phosphate can accumulate and accumulate in the aquarium. You are in the usual concentrations not toxic to the fish. Their effect on plants and algae is discussed. You are at high levels promote the growth of algae and inhibit the plants.
Conclusion
In the early stages it may be important to the water values to know, as a guideline range but also the details of the water utility and the course of ammonia and nitrite to pursue, as a decision aid for restocking time of the aquarium.
The longer it runs, but this hobby, the less frequently you will take up water tests. Experienced aquarists use this data only occasionally, generally only when their Particularly water recycle.
who prepared his water, be it with peat, reverse osmosis, ion exchange resins or with mineral acids, is well advised to review certain water levels.
The knowledge and control of water levels also helps in understanding the biological and chemical processes in the aquarium.
a successful aquarium is possible without water testing and periodic inspection.
