Calcium Reactor

A reactor chamber that dissolves calcium carbonate media (aragonite, coral rubble) with CO2-lowered pH - continuously supplying calcium and alkalinity to SPS-heavy reef tanks.

Price: Premium For: Saltwater $300-$2,500

📖 Overview

For large SPS-dominated reef tanks with high calcium demand, a calcium reactor is the most efficient way to keep calcium, alkalinity, and magnesium supplemented. Aquarium water is dripped through a media chamber where CO2 has dropped the pH; this dissolves calcium carbonate media into a nutrient-rich effluent that drips back into the sump. Once tuned, a calcium reactor is set-and-forget for weeks.
