Salifert Magnesium Profi-Test Kit

The Salifert Magnesium Profi-Test Kit is designed to accurately measure magnesium levels in marine aquariums, helping maintain optimal conditions for coral, algae and plant growth. Magnesium supports photosynthesis, stabilizes calcium and alkalinity levels, and prevents hidden ionic imbalances in reef systems. The kit provides approximately 50 tests and measures in increments of 30 mg/L for precise monitoring.
