The Modern Reef PRECISION Reference Solution is a laboratory-precision reference solution for testing and calibrating water tests in marine aquariums.

It is used for:

• Checking the accuracy of liquid tests.
• Calibrating automatic analyzers.
• Calculating correction factors if measurements deviate from reference values.

It covers the parameters:

• Salinity (PSU)
• KH (Carbonate hardness)
• Calcium (Ca)
• Magnesium (Mg)
• Potassium (K)
• Strontium (Sr)
• Iron (Fe)
• Iodine (I)
• Silicon (Si)
• Boron (B)
• Bromine (Br)
• Fluorine (F)
