Definition of PH and how to decrease pH in water

Definition of PH and how to decrease pH in waterPHpH is an expression of the concentration of hydrogen ions ( H + ) in water . The amount stated in the minus logarithm of the concentration of ions H. For example , if there is a statement pH 6 , it means the concentration of H in the water is 0.000001 part of the total solution . Due to write 0.000001 ( imagine if pH 14 ) is too long then the number of people melogaritmakanthus widened -6 . But because there is a sign - ( negative ) behind the figure , the less practical , then multiply again by the sign - ( minus ) in order to obtain a positive number 6 . Therefore , pH is definedas " - ( minus ) the logarithm of the concentrations of H ions " .

              
pH = - log ( H + )Noteworthy is that the difference of one pH unit number that means kosentrasinya difference is 10-fold . Thus , if the difference of the numbers is 2 then the concentration difference is 10x10 = 100 times . For example, pH 5 shows the concentration of H as 0.00001 or one hundred thousandth ( a hundredth thousand ) while the pH 6 = 0.000001 or one millionth ( a millionth ) .Thus if we lower the pH from 6 to 5 means that we increase the concentration of H + IOB much as 10-fold . If we suppose that the pH of the sugar , then by lowering the pH from 6 to 5 , it means that the solution is now 10 times sweeter than before .
Not all creatures can survive the change of pH value , for that nature has provided a unique mechanism for the changes did not occur or did not occur , but by how slowly . This defense system known as the buffer capacity of early development .Ph is very important as a water quality parameter because it controls the rate of speed of reaction types and some of the material in the water . Besides fish and other aquatic creatures living in a certain pH interval , so that by knowing the pH value then we will know if the water is appropriate or not to support their lives .PH scale ranges from 0 ( very acidic ) to 14 ( very alkaline / alkaline ) . PH values ​​less than 7 indicate acidic environment whereas a value above 7 indicates alkaline environments ( alkaline ) . While pH = 7 is referred to as neutral .Fluctuations in the pH of water is determined by the alkalinity of the water . If alkalinitasnya high then the water will easily restore the pH to its original value , of any " disruption " for altering the pH .Thus the key lies in the handling of the pH decrease in alkalinity and water hardness . If this had been controlled by the decrease in pH would be easier to do .handling pHAs mentioned earlier , interference or alteration of the pH value would be more effective if the alkalinity ditanganai first. Here are some ways pangananan pH , which , if observed farther , likely to lead to hardness or alkalinity handling .The decrease in pHTo lower the pH , it must first be measured KH . If the value of KH is too high ( 12 or more ) then the KH terleibh first need to be lowered , which usually is automatically followed by a decrease in pH value . If nilia pH is too high ( more than 8 ) , while KH is quite good ( between 6 -12 ) then it is a reflection of the poor balance .The decrease in pH can be done by passing the water through the peat ( peat ) , generally used is peat moss ( peat moss derived from ) . can also be done with water and replaced them with lower berkesadahan water , rain water or boiled water , deionized water , or distilled water ( distilled water ) .Besides it can also be done by adding bogwood into akuairum . Bogwood is a kind of timber that can possess the ability to adsorb hardness . Ketapan same function as leaves , wood and the like acids .
Increasing the pHRaising the pH can be done by providing intensive aeration , water skipping past the coral fragments , fragments of shells or limestone pieces . Or by adding decorations such as tufa limestone -based , or coral sand . Or by water replacement
