Salifert Magnesium (mg) Test Kit

Overview

The Salifert Magnesium Test Kit lets reef keepers accurately measure magnesium, an element present in natural seawater at roughly 1350-1500 mg/L and essential to a healthy marine system. Correct magnesium indirectly drives fast coral and calcareous algae growth by helping you hold proper calcium and alkalinity. Since magnesium is depleted by algae growth and heavy kalkwasser use, regular testing keeps your parameters on track.

Key Features

• Accurately measures aquarium magnesium levels
• Helps maintain calcium and alkalinity balance
• Supports fast coral and calcareous algae growth
• Targets the natural seawater range of 1350-1500 mg/L
• Useful for tracking depletion from algae and kalkwasser
• Designed for marine and reef aquariums
