Pharmaceutical-Grade Magnesium Chloride Aquarium Supplement
Reef Endurance Magnesium Chloride is a pharmaceutical-based aquarium supplement that mixes crystal clear with no unwanted impurities. Maintaining a proper magnesium level of 1200-1350ppm in reef aquaria helps achieve the essential balance of calcium and alkalinity in the aquarium by preventing excess calcium carbonate precipitation. For best results, use in conjunction with Reef Endurance Magnesium Sulfate for a complete balance.
Key Features:
- Replenish and maintain Magnesium levels in a reef aquarium
- Resealable Packaging
- Mixes Clear

Stock Solution Mixing Instructions:
1 gal RO/DI + 888 grams (about 5 cups) of Magnesium Chloride + 498 grams (about 3 cups) of Magnesium Sulfate
- Fill a one-gallon container half full of RO/DI or distilled water
- Add 888 grams (about 5 cups) of Magnesium Chloride and 498 grams (about 3 cups) of Magnesium Sulfate to the container.
- Fill the remainder of the container with RO/DI or distilled water and secure the cap.
- Shake vigorously and allow to dissolve for 24 hours altogether.
Tip: A precipitate (calcium sulfate) will form, which is normal. Adding this to the aquarium will not cause any problems.
Dosing Instructions:
1 mL of Magnesium Chloride stock solution will raise magnesium by approximately 13 ppm in 1 USG. Increasing magnesium by more than 50 ppm per day is not recommended.
Tip: If you have issues raising your alkalinity levels, ensure your aquarium magnesium level is between 1200 and 1350 ppm.
