Description

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.

• Measurement range: 300 – 500 mg/l (ppm)
• Accuracy: 5 mg/l
• For determining the K concentration in saltwater aquaria
• Sufficient for approximately 50 applications
• Incl. potassium standard to check function and shelf life of the test reagents

If the potassium level in the water is too high, we recommend doing a partial water change.

Shelf life: 6 months after opening. Store in a cool, dark place.
