Aquavitro Ions 1L – Ultra-Pure Magnesium Supplement for Reef Aquariums
Product Overview
Aquavitro Ions delivers the highest concentration of fully dissolved magnesium (90,000 mg/L) available on the market—without the ammonia contamination found in many competing products. Formulated for reef aquariums, Ions helps restore and maintain optimal magnesium levels, which are essential for calcification, coral health, and ionic balance.
Many liquid magnesium supplements use magnesium chloride contaminated with ammonia—not Aquavitro Ions. Its proprietary process ensures a clean, ammonia-free solution ideal for even the most sensitive reef systems.
Also includes strontium and boron in the natural seawater ratio (1.7:1) for long-term ionic stability.

Why Magnesium Matters in Reef Tanks
Magnesium:
-
Stabilizes calcium and alkalinity
-
Helps prevent carbonate precipitation
-
Is vital for coral skeletal formation
-
Affects pH regulation and coral coloration
Signs of low magnesium:
-
pH below 8.0
-
Inability to maintain calcium levels
-
Poor coral growth or tissue recession
Use Seachem Reef Status: Magnesium & Carbonate/Borate to test magnesium levels regularly.
Directions for Use
Beginner:
Use 5 mL per 90 L (25 US gallons) twice weekly. Test weekly and adjust as needed.
Advanced:
Check magnesium level, then dose as follows:
-
5 mL per 90 L will raise Mg by 5 mg/L
-
Do not exceed 25 mL per 90 L per day
-
Target magnesium range: 1200–1350 mg/L
Can be safely dosed daily and alongside any other Aquavitro product (e.g. Calcification, Eight.Four, Balance, etc.)

FAQs
Why isn't my magnesium increasing even with daily dosing?
If your levels are very low (e.g., 1050 mg/L), it may take multiple doses over several days or increased dosing (up to 5x standard). Magnesium is slow to rise in large systems. Consider using a salt mix with higher magnesium (e.g., Aquavitro Salinity).
Will this raise strontium too much?
No. Strontium is dosed in natural seawater proportion, and its uptake rate typically follows magnesium. Even if it slightly accumulates, there's a 10x safety margin. Regular water changes will prevent excess buildup.
Does the bottle have a second seal?
No. Aquavitro uses a special leak-proof cap system—an inner seal is not required. The cap ensures long-term freshness and protection from contamination.
