Aquavitro Ions-350mL

A concentrated liquid magnesium supplement for reef tanks, made without the ammonia that many plain magnesium-chloride products carry.

Key features

• Restores magnesium from a very concentrated (90,000 mg/L) fully dissolved source
• Made without the ammonia byproduct of ordinary magnesium chloride
• Includes strontium and boron in a seawater ratio to avoid ionic imbalance

Correct magnesium here when a test shows it low, which often unlocks stubborn calcium and alkalinity; if those two read fine, dose the supplement that is actually short. Part of our water care. Available for local pickup at our Lethbridge store.
