Reef Octopus VarioS CR3000 Dual 7-Inch Chamber Calcium Reactor | Up to 580 Gallons

Ultimate Stability for Growing Reef Aquariums

The Reef Octopus VarioS CR3000 Dual Chamber Calcium Reactor was designed for reef hobbyists who demand exceptional stability, intelligent control, and premium performance. Rated for aquariums up to 580 gallons, the CR3000 delivers a continuous supply of calcium, alkalinity, and trace elements to support thriving SPS dominant and mixed reef aquariums.

Featuring a premium dual chamber design, controllable VarioS 4 DC recirculation pump, reverse flow technology, and CO2 recirculation capabilities, the CR3000 maximizes media utilization while helping buffer outgoing effluent pH for improved aquarium stability.

When coral growth begins to outpace traditional dosing methods, the VarioS CR3000 provides one of the most consistent and reliable solutions available to reef keepers today.

Why We Love It

There comes a point in every successful reef aquarium when maintaining stability becomes more challenging than growing coral.

For heavily stocked SPS aquariums, dosing requirements can quickly become expensive, time consuming, and difficult to manage. Calcium reactors provide something every reef keeper strives for: consistency.

The CR3000 isn't simply replacing two part dosing. It's delivering calcium and alkalinity twenty four hours a day while helping maintain the stable water chemistry corals love.

Stable tanks grow beautiful corals. Beautiful corals create unforgettable reef aquariums.

Why Choose a Dual Chamber Reactor?

The CR3000 utilizes a secondary chamber to help improve media utilization and buffer outgoing effluent before it returns to your aquarium.

Benefits include:

• Improved CO2 Utilization
• Enhanced Calcium and Alkalinity Delivery
• Improved pH Stability
• Increased Media Efficiency
• Reduced Maintenance Requirements
• Exceptional Long Term Stability
• Ideal for High Demand Reef Systems

Important Information

A calcium reactor requires additional equipment not included with the reactor including:

• CO2 Cylinder
• CO2 Regulator
• Calcium Reactor Media
• Feed Pump or Feed Line
• pH Probe (Recommended)
• Aquarium Controller (Optional)

For best results, we recommend pairing your calcium reactor with a premium pH controller or aquarium controller system for intelligent monitoring and automation.
