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.\u003c\/p\u003e\u003cp\u003eThe defining mechanical advantage of the 300PRO is its flagship \u003cb\u003eWater Blaster 10000 recirculation pump\u003c\/b\u003e. 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 \u003cb\u003ereverse-flow engineering design\u003c\/b\u003e, 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.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eCommercial Scale Framework:\u003c\/b\u003e Effortlessly satisfies the high mineral draw associated with large-scale small polyp stony (SPS) displays and multi-tank coral installations.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eWater Blaster Power House:\u003c\/b\u003e High-efficiency, 2,600 GPH max-flow recirculation pump yields immense torque and massive head pressure parameters.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eCO2​ Recirculation System:\u003c\/b\u003e Captures and recycles pockets of undissolved gas collecting in the upper neck assembly, extending the operational lifecycle of your pressurized CO2​ bottles.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eAutomation Ready Probe Port:\u003c\/b\u003e Securely houses electronic pH controller probes directly inside the primary mixing zone for reliable, automated gas solenoid execution.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003ePressure-Sealed Integrity:\u003c\/b\u003e Built with heavy-wall union connections and secure top-flange fastening hardware to ensure 100% leak-proof dry cabinet or external floor deployment.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSystem Capacity Handling\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eHeavy Demand (Commercial SPS Facility):\u003c\/b\u003e 1,500 Gallons\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eMedium Demand (Public Aquarium Exhibit):\u003c\/b\u003e 2,100 Gallons\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eLight Demand (Large Fish Hatchery System):\u003c\/b\u003e 2,700 Gallons\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003ePlease contact us at\u003ca href=\"%5C%22mailto:support@coralvue.com%5C%22\"\u003e Support@coralvue.com\u003c\/a\u003e should you need commercial equipment to suit your specific needs.\u003c\/p\u003e","brand":"Reef Octopus","offers":[{"title":"Default Title","offer_id":50484002881784,"sku":"OCT-CR300PRO","price":4273.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/6909\/5160\/files\/f739646a8c4cfabd99de5137f9664e49.jpg?v=1789093009","url":"https:\/\/www.blueearthaquariums.com\/products\/octo-cr-300pro-commercial-calcium-reactor","provider":"Blue Earth Corals","version":"1.0","type":"link"}
