When considering a new aquarium of hardness and pH of your tap water is the first thing you must evaluate, once you know the characteristics of your water supply, you can choose fish that would be adapted your water conditions. Otherwise, you will need to adjust the chemistry of tap water to meet the requirements of the fish you choose.
The pH refers to the power of hydrogen, and is measured on a logarithmic scale from 0 to 14. As you noticed May pH is closely linked to the hardness of water, generally a higher concentration of salts, means a higher pH and a lower concentration of salts, a low pH.
A pH of 0.0, the most acidic, represents a normal hydrogen ions (H).
A pH of 7.0, is neither acidic nor alkaline and regarded as neutral by having an equal number of hydroxyl and hydrogen ions.
A pH of 14.0, the highest alkaline solution is a normal hydroxyl ions (OH-)
You would need a thorough knowledge of basic chemistry to understand the true meaning of pH in water, and I have no diploma in this area, too, for our purpose we will define acidity and 'alkalinity in terms of number of ions in the water.
If there is an excess of hydrogen ions (H), then water is said to acid, on the other hand if there is an excess of negatively charged hydroxyl ions (OH-), then the water is alkaline.
Table pH is logarithmic, meaning that a change in pH 7.0, for example, a pH of 6.0 is a tenfold increase in acidity, or ten times more hydrogen ions (H) concentration. To give a more powerful example:
pH 8.0 is 100 times more than the alkaline pH 6.0 or 100 times more than the negatively charged hydroxyl ion (OH-).
It is necessary to maintain a stable pH, and in the right range, to maintain the health of tropical fish and colorful.
As a general guide, spawning fish such as Tetras, Angelfish, and Rasbora prefer a pH of 6.5.
While on the lives of species such as Mollies, Swordtails, guppies and thrive at a pH of 7.5.
When maintaining a mixed community of tolerant species in the aquarium you could have the pH to a neutral pH of 7.0
Too acidic or alkaline conditions in the aquarium and fluctuations of pH should be avoided, it will cause stress for your fish, and environmental stress leads to reduced resistance to disease, poor fish color and lack of appetite.
All changes to the pH of your aquarium water must be carried out slowly over a number of days to avoid stressing your fish. A minimum pH of 6.5 is reasonable; filters are less effective below this level due to reduced growth and survival of bacteria nitrification.
Species requiring a pH lower than 6.5 should have frequent water changes to prevent the accumulation of nitrogenous waste. As I mentioned earlier, pH is closely linked to the hardness of water, if your pH is high, it is likely that your water is rich in calcium bicarbonate, a buffer pH, and acts against the process aimed at changing the pH.
For this reason, I use a pH commercial, which sets the pH to a fixed level. He then held the buffers or pH level and the fight against the pH bounce (ordinary adjusters that temporarily changes in pH, and water can quickly return to its previous state, we know what the pH bounce).
Unfortunately, there are a number of processes that occur naturally in the aquarium that can threaten to change the pH ideal that you provided for your fish. The filters task of breaking toxic waste ends in the formation of nitrates, which are a salt of nitric acid and exhaust can buffer the pH and cause sudden drops in pH.
This can be avoided with regular changes of water (which are part of regular maintenance anyway), which will dilute nitrates, it will be more effective when combined with cleaning of any buildup of debris in the substrate.
Carbon dioxide (CO2) is introduced into water by the respiration of fish, among other things, that when dissolved in water it forms carbonic acid (C2CO3), it also can add to a drop in pH. Good ventilation and circulation assist in the elimination of CO2 in the atmosphere and reduce its effect on pH.
The surface of an aquarium must be wider than deep, it is giving a larger area for a volume of water, which helps evaporation of the effect of unwanted elements, and is also very beneficial to the process of absorption.
The two elements, hydrogen and oxygen are chemically bonded together and are not easily released. Therefore, the fish can not use oxygen that is in water molecules. Water is able to dissolve many substances, and oxygen is no exception.
Oxygen is constantly absorbed from the air, the water and circulates through it. Fish use of dissolved oxygen in water through gills, then excrete carbon dioxide from their waste through their gills to water. In this way gills are comparable to the lungs.
Ventilate your water with air or other stones after an air pump, or through the venturi an internal power filter or head of the help in the process of oxygenation, the more for bubbles to the surface is the best opportunity of oxygen being absorbed by them.
However, this is only part of the process, the slow rise of bubbles are also able to carry the waste gases, like carbon dioxide expelled from your fish to the surface and the atmosphere, which reduced its effect on pH.
