VarioS CR220 9 inch Calcium Reactor

The Reef Octopus VarioS CR220 9-Inch Calcium Reactor is the largest single-chamber model in the VarioS line, built for demanding reef systems with high calcium and alkalinity draw. The DC variable-speed pump and reverse-flow circulation carry over from the smaller VarioS models, scaled to a 9-inch chamber for maximum media volume.

• Body: 9-inch reaction chamber — largest single-chamber VarioS model
• Pump: VarioS variable-speed DC pump, reverse-flow design, 2-year warranty
• Features: precision effluent control valve, quick-connect fittings, removable lid, built-in pH probe holder and auto-fill bubble counter
• Requires: pH probe and controller (sold separately)

For systems that need more capacity than the CR220 offers, the dual-chamber CR3000D steps up further by running two reaction chambers in series.

Compatible replacement parts: VarioS pump kits and bubble counters for the CR220.
