Product details
Seachem Aquavitro Reef Ions 350mL (7561) is a liquid reef supplement designed to restore magnesium in marine aquariums. Magnesium is used in the calcification process of reef organisms and also plays roles across a range of organisms in the tank, from coralline algae to bacteria and even fish. In practice, this product is used when magnesium levels test low, helping support overall ionic balance so calcium levels can be maintained more reliably.
Features:
- Restores magnesium in reef systems by using fully dissolved magnesium
- Highly concentrated formula at 90,000 mg/L
- Formulated to avoid ammonia—described as the first and only liquid magnesium supplement that does not contain ammonia
- Helps prevent problems associated with magnesium deficiency (including depressed pH and difficulty maintaining proper calcium levels)
- Designed with a fully dissolved magnesium approach to improve availability to reef organisms
- Also includes strontium and boron in a NSW ratio of 1.7:1 to help avoid ionic imbalance with long-term use
- Recommended to confirm needs with magnesium testing (e.g., Seachem Reef Status®: Magnesium & Carbonate) before dosing
