VarioS CR200 8-inch Calcium Reactor

The Reef Octopus VarioS CR200 8-Inch Calcium Reactor steps up chamber size to 8 inches for larger reef systems, keeping the DC variable-speed pump and reverse-flow circulation that define the VarioS calcium reactor line. The larger chamber holds more aragonite media, extending time between refills.

• Body: 8-inch reaction chamber
• 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)

The 8-inch chamber is the mid-size option in the VarioS line — a common fit for systems that have outgrown the CR140 but don't need the CR220's largest single-chamber capacity.

Compatible replacement parts: VarioS pump kits and bubble counters for the CR200.
