Reef Advantage Magnesium is a potent (80,000 ppm) specially formulated mix of magnesium, chloride, and sulfate salts aimed at replenishing low magnesium levels while ensuring minimal disruption to the ionic balance typical of natural seawater. This product is free from ammonia.


KEY FEATURES:

  • Highly concentrated, harmoniously blended magnesium source
  • Completely Ammonia-Free
  • Essential for maintaining ionic balance

DIRECTIONS:
Beginner
Administer 5g (1 level teaspoon) for every 80L (20 gallons) twice weekly. Dissolve in a minimum of 250mL (1 cup) of freshwater. For accurate measurements, utilize the Seachem Digital Spoon Scale.

Advanced
Monitor magnesium levels, then adhere to the addition schedule mentioned above until magnesium reaches between 1,200-1,350 mg/L. Each 5 g per 80 L will increase magnesium by roughly 5 mg/L. You may adjust the amount or frequency, but do not exceed 25 g per 80 L daily. After reaching the desired level, use as necessary to sustain magnesium levels.
