Reef Octopus 300PRO Commercial Calcium Reactor
The Reef Octopus 300PRO Commercial Calcium Reactor (SKU: OCT-CR300PRO) is a heavy-duty, high-capacity external mineral replenishment system engineered to sustain absolute water parameters in large-scale marine systems up to 2,700 gallons. When managing fragile stony coral ecosystems, public exhibits, or intensive grow-out facilities on a commercial scale, traditional hobbyist dosing regimens are rendered expensive, labor-intensive, and volatile. The CR-300PRO automates the delivery of bio-available calcium, carbonate alkalinity, strontium, and essential trace minerals. By circulating raw system water through its spacious 12-inch reaction tower alongside regulated carbon dioxide (CO2), it safely depresses internal pH to an acidic state, continuously melting crushed aragonite media back into its structural elemental constituents.
The defining mechanical advantage of the 300PRO is its flagship Water Blaster 10000 recirculation pump. Operating at an industrial-strength 125 Watts, this high-volume water mover features a premium silicon carbide shaft and bearing assembly. This ultra-hard material barrier successfully resists the aggressive friction and scoring typical in a highly abrasive aragonite mineral suspension loop, guaranteeing non-stop runtime with zero frozen shafts. Embodying an optimized reverse-flow engineering design, the pump forces water upward through the 45-liter media column. This uniform upward hydraulic pressure keeps large quantities of heavy aragonite beds loose and moving, completely avoiding the clumping, cementing, and anaerobic channeling that plagues flat-bottom reactors. Finished with thick high-strength union plumbing joints, an accessible removable lid flange, and independent flow tuning valves, this commercial tower supplies elite chemical stability for world-class aquatic displays.
Key Features
Commercial Scale Framework: Effortlessly satisfies the high mineral draw associated with large-scale small polyp stony (SPS) displays and multi-tank coral installations.
Water Blaster Power House: High-efficiency, 2,600 GPH max-flow recirculation pump yields immense torque and massive head pressure parameters.
CO2 Recirculation System: Captures and recycles pockets of undissolved gas collecting in the upper neck assembly, extending the operational lifecycle of your pressurized CO2 bottles.
Automation Ready Probe Port: Securely houses electronic pH controller probes directly inside the primary mixing zone for reliable, automated gas solenoid execution.
Pressure-Sealed Integrity: Built with heavy-wall union connections and secure top-flange fastening hardware to ensure 100% leak-proof dry cabinet or external floor deployment.

Unfasten the upper heavy-duty flange thumbscrews and lift away the sealing lid from the primary 12-inch cast acrylic tower.
Rinse your preferred high-quality, large-grain coarse aragonite media thoroughly with RO/DI water to clear out fine powder dust, then pack up to 45 Liters into the chamber body.
Re-seat the lid flange, verifying that the heavy structural silicone gasket rests completely flat against the collar, and torque down the fastening hardware evenly.
Insert your electronic pH controller probe into the designated primary chamber compression port and tighten the locking nut to establish a watertight seal.
Plumb your external system feed water pump (capable of delivering 600–1,000 GPH) and your regulated CO2 line to their respective intake connection adapters.
Fill the reactor tower completely with water to displace any trapped air pockets, verify water is discharging down-stream, select your internal valve adjustments, and plug the Water Blaster 10000 into a GFCI outlet.
Pro Tips:
Coarse Media Only. Always utilize a high-quality, large-grain coarse aragonite media (such as large coral bones or premium coarse chips) inside the CR-300PRO. Fine, sandy, or small-grained media will rapidly melt down into a dense, muddy sludge inside the acidic internal environment. This mud will choke the lower distribution plate, stall water flow, and potentially bind or permanently score the Water Blaster pump's internal shaft assembly.
Failsafe Solenoid Programming. To protect your commercial system from over-acidification, always plug your CO2 regulator solenoid into an electronic aquarium controller or dedicated pH monitor. Program the controller to instantly cut power to the CO2 gas solenoid if the internal chamber pH dips below 6.5. This failsafe keeps the aragonite from turning into mush during an unforeseen system fluctuation.
Effluent Scaling Protocols. Because the effluent fluid leaving the reactor is highly saturated with calcium and carbonate ions, small mineral crusts (calcium scaling) can slowly precipitate inside the discharge plumbing line over time. Inspect your daily drip or flow rate weekly. Every few months, clear out the line lines by flushing a brief run of warm RO/DI water or a mild white vinegar solution through the effluent plumbing to dissolve hidden mineral blockages.
