Monitors the water values in the aquarium easily and reliably.
Determined: pH, carbonate hardness, CO2 directly, iron, magnesium, potassium, phosphate, silicate and nitrate.

Add reagents to the water samples, compare to the color chart, read the value and check the analysis sheet to see what measurements are recommended if necessary.

Comparison systems take into account the natural color of the water (compensate for it).
