Features:
For high precision determination of the potassium concentration in saltwater
Potassium is a vitally important macro-nutrient for all living beings. In natural ocean water, this alkali metal is present in an average concentration of 408 mg/l. In a saltwater aquarium, the potassium concentration is usually kept stable by regularly changing the water. Nevertheless, a lack of potassium can occur in individual aquariums tanks due to the use of zeolites and other adsorbents. One sign of a possible lack of potassium is clear discolouration of corals and retraction of polyps. The potassium level in a saltwater aquarium should be checked regularly to ensure that the level is between 380 and 420 mg/l.
With the high resolution titration test Tropic Marin®Potassium Test Professional the potassium concentrations can be determined reliably with a resolution of 5 mg/l.

How to use:
Note: The precision of the measurement results may be increased by determining a „correction value“. For this purpose a measurement with reagent “Standard” (potassium) is carried out. This measurement indicates the correction value that should be included during each potassium measurement. We recommend determining the correction value again every 3-4 weeks.
