VarioS CR3000 Dual 7inch Chamber Calcium Reactor

The Reef Octopus VarioS CR3000D Dual 7-Inch Chamber Calcium Reactor runs two 7-inch reaction chambers in series, giving CO2-charged water a second pass through fresh aragonite media for more complete dissolution than a single-chamber design. It keeps the DC variable-speed pump and reverse-flow circulation of the rest of the VarioS line.

• Body: dual 7-inch reaction chambers in series
• Pump: VarioS variable-speed DC pump, reverse-flow design, 2-year warranty
• Features: precision effluent control valve, quick-connect fittings, removable lids, built-in pH probe holder and auto-fill bubble counter
• Requires: pH probe and controller (sold separately)

The dual-chamber design is the key difference from the CR220 — rather than one larger chamber, water gets a second full pass through media, which tends to improve dissolution efficiency on demanding systems.

Compatible replacement parts: VarioS pump kits and bubble counters for the CR3000D.
