The AquaReady cTech T-2 Calcium Reactor is designed to simplify calcium dosing in reef aquariums by efficiently mixing saltwater, calcium carbonate, and CO2 within its compact reaction chamber. This up-flow design eliminates the need for daily two-part dosing, ensuring a consistent supply of essential elements to promote coral growth and maintain water chemistry stability. Featuring a built-in pH probe holder and an integrated CO2 recovery system, this reactor offers precise control over effluent drip rates through its high-quality pinch valve, minimizing waste and reducing operational costs.
