Octo CR200 Calcium Reactor

Reef Octopus VarioS CR200 8-inch Calcium Reactor

The Reef Octopus VarioS CR200 (OCT-CALR200) is a high-performance solution for aquarists looking to automate the complex task of maintaining alkalinity, calcium, and essential trace elements. Quality, modern design, and DC controllability define the VarioS series, making it a premier choice for demanding reef systems. Unlike traditional AC-powered reactors, the CR200 uses the variable-speed VarioS-4 pump, allowing users to fine-tune the recirculation rate for optimal media dissolution.

The reactor employs a sophisticated reverse-flow design, forcing water upward through the media to maximize contact time and prevent "channeling" or dead spots. This ensures that every ounce of aragonite media is utilized effectively. With its built-in CO2 recirculating feature, the CR200 recovers unused gas to increase efficiency and lower the overall pH within the chamber more effectively. The unit is thoughtfully designed with a precision effluent control valve and quick-connect fittings, simplifying the setup and tuning process for consistent daily mineral delivery.

Key Features:

• Controllable VarioS DC Pump: Offers variable speed settings, a feed mode, and high-efficiency performance with a 5-year warranty. 
• Reverse Flow Design: Maximizes water-to-media contact while ensuring even dissolution of the aragonite. 
• Comprehensive CO2 Tools: Includes a built-in bubble counter and a dedicated pH probe holder (probe sold separately) for total chamber monitoring. 
• Auto Fill Feature: Integrated bubble counter and gas recovery system reduce CO2 waste. 
• Durable Construction: Built with solid cast acrylic and 1/4" quick-connect fittings for a leak-proof experience. 
• Easy Access Lid: Designed for simple media refills and routine chamber maintenance.

Ideal For:

• High-Demand SPS Tanks: Perfect for systems requiring high amounts of calcium and carbonate. 
• Medium to Large Reefs: Rated for systems between 300 and 500 gallons, depending on bioload. 
• Tech-Forward Hobbyists: Those who prefer the quiet operation and micro-adjustability of DC-powered equipment. 
• Minimalist Sump Spaces: Compact footprint considering its high media capacity.
