Alcalinity characterizes the ability-tampone, that is the capacity necessary to maintain the pH value of fresh and marine water.
It is formed through the amount of hydrogen carbonates present in the water and with the increase of the pH value also through hydroxide ions.
A quantity of hydrogen carbonates too low can result in a decrease in pH value, very dangerous for the life of many fishes and invertebrates.
Should alkalinity range between 8 and 12? dKH (German carbonate grades).
The new KH Professional test Tropic Marin is one of the most precise and allows to determine the value of kh with a resolution up to 0.1° dH.
The high precision is given by the use of a 1ml syringe with a graduated scale scanned in values of 0.01ml. The color changes quickly from turquoise to pink and is easily visible.
The content is sufficient for about 100 tests at a resolution of 0.2°dH in water with 10°dH or 50 tests at a resolution of 0.1°dH in water with 20°dH.
