Aquavitro Element Calcium Reactor – Maintain Calcium, Magnesium & Alkalinity Balance
Product Overview
The Aquavitro Element Calcium Reactor is a compact, high-efficiency reactor engineered to maintain a stable and balanced supply of calcium, magnesium, and alkalinity in reef aquariums up to 250 US gallons / 950 liters.
By dissolving a media such as Seachem Reef Reactor using CO₂ acidification, this reactor ensures the continuous release of vital reef-building elements. It’s ideal for advanced reefkeepers looking to maintain long-term coral health and stable water chemistry without daily dosing routines.

How It Works
-
CO₂ Injection lowers pH inside the reactor.
-
Reactor media dissolves, releasing calcium, magnesium, and carbonates.
-
Effluent output delivers balanced elements directly to your system.
-
pH probe & controller (sold separately) monitor CO₂ and optimize performance.
