Test for the measurement of 'acidity in marine aquariums
The pH is the value that indicates the acidity or alkalinity of a solution.
When the measurement has a value close to pH 7 if it determines neutrality.
In marine aquarium this value should be kept between pH 8.0 and pH 8.4.
A deviation from these parameters may be caused by a weak water movement in the aquarium or by a low concentration of the dissolved carbonates.
Microsoft recommends that you also periodically measure the carbonate hardness expressed in degrees and KH, if in default, reestablish the levels with "SHG KHPlus", commercially available both in liquid and powder.
