Salifert Test Kit Magnesium

Product details

Salifert Test Kit Magnesium is a marine aquarium test kit designed to measure magnesium levels in saltwater. Magnesium is present in natural sea water in a fairly high concentration (about 1350–1500 mg/L) and is an essential element of chlorophyll, which supports photosynthesis. Practically, magnesium also helps maintain the balance between calcium and alkalinity by slowing down the formation of calcium carbonate, which can otherwise absorb important trace elements. By testing magnesium regularly, you can spot depletion that may occur from algae growth or from pushing calcium/alkalinity inputs too far (for example with excessive kalkwasser). This kit is for marine water only and is used to confirm whether your magnesium is staying within a suitable range for stable reef conditions.

Features:

• Measures magnesium for marine (saltwater) aquariums only
• Provides measurements in steps of 30 mg/L for controlled adjustments
• Designed to be easy to use while remaining accurate for routine testing
• Results are not affected by strontium and calcium interference in typical aquarium ranges
• Helps support more stable calcium and alkalinity management by maintaining the magnesium/calcium/alkalinity relationship
• Useful for monitoring depletion from factors such as algae growth or excessive calcium/alkalinity dosing

Specifications:

• Test target: Magnesium (Mg) in marine water
• Measurement resolution: 30 mg/L steps
• Number of tests: Up to 50 tests
• Interference notes: Results are not affected by strontium; calcium interference is not expected when total calcium and strontium is between 200 and 650 ppm
