Aquavitro Ions is a concentrated magnesium supplement designed specifically for marine and reef aquariums. Magnesium is crucial for maintaining proper calcium and alkalinity balance, as well as supporting healthy coral growth and skeletal development. Ions provides high-purity, bioavailable magnesium in a balanced chloride-to-sulfate ratio to match natural seawater—making it a safe and effective solution for reefkeepers.

Frequently Asked Questions (FAQ)
Q: Why is magnesium important in a reef tank?
A: Magnesium prevents calcium and carbonate from precipitating, helping maintain stable alkalinity and calcium levels essential for coral growth.
Q: How do I know if my tank needs more magnesium?
A: Signs of magnesium deficiency include poor coral calcification, difficulty maintaining calcium/alkalinity, and slowed coral growth.
Q: Is Ions safe for soft corals and invertebrates?
A: Yes. Ions is reef-safe and suitable for all marine life when used according to dosage instructions.
Q: Will Ions affect pH or alkalinity?
A: No. It is formulated to adjust magnesium only, with no significant effect on pH or KH.
Q: Can I use Ions with a calcium reactor?
A: Yes. Ions is ideal for supplementing magnesium in systems using calcium reactors, which often lack magnesium supplementation.
Q: What makes Ions different from other magnesium supplements?
A: Ions uses a chloride-to-sulfate ratio that closely resembles natural seawater, avoiding unwanted ionic imbalances.
Q: How often should I test magnesium?
A: Test weekly or after water changes to ensure levels remain in the optimal range of 1,250–1,350 mg/L.
