Aquarium water is circulated through this chamber along with carbon dioxide (CO₂). The CO₂ lowers the pH in the chamber to an acidic level which dissolves the carbonate minerals into the aquarium water, along with nearly all the minerals and trace elements the coral needs in order to grow.\u003c\/p\u003e\u003cp\u003eWhen set up properly with an external controller and probe, calcium and alkalinity supplementation can be automated with very little monitoring and maintenance.\u003c\/p\u003e\u003c!-- more --\u003e\u003ch2\u003eFeatures \u0026amp; Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eControllable and variable speed DC pump for energy-efficient and silent operation\u003c\/li\u003e\n\u003cli\u003eReverse flow and CO₂ recirculating design\u003c\/li\u003e\n\u003cli\u003ePrecision effluent control valve\u003c\/li\u003e\n\u003cli\u003eBuilt-in bubble counter for monitoring of CO₂ drip rate\u003c\/li\u003e\n\u003cli\u003eProbe holder with plug (pH probe not included)\u003c\/li\u003e\n\u003cli\u003eHigh quality handmade solid cast acrylic construction\u003c\/li\u003e\n\u003cli\u003eRemovable lid for easy maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Data\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct\u003c\/th\u003e\n\u003cth\u003ePump\u003c\/th\u003e\n\u003cth\u003ePump Power (W)\u003c\/th\u003e\n\u003cth\u003eDiameter (mm)\u003c\/th\u003e\n\u003cth\u003eFootprint (mm)\u003c\/th\u003e\n\u003cth\u003eHeight (mm)\u003c\/th\u003e\n\u003cth\u003eMedia Capacity (L)\u003c\/th\u003e\n\u003cth\u003eTank Volume (L)\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalReact 140\u003c\/td\u003e\n\u003ctd\u003eVarioS 2\u003c\/td\u003e\n\u003ctd\u003e25\u003c\/td\u003e\n\u003ctd\u003e140\u003c\/td\u003e\n\u003ctd\u003e310 x 230\u003c\/td\u003e\n\u003ctd\u003e580\u003c\/td\u003e\n\u003ctd\u003e3.9\u003c\/td\u003e\n\u003ctd\u003e400-800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalReact 200\u003c\/td\u003e\n\u003ctd\u003eVarioS 4\u003c\/td\u003e\n\u003ctd\u003e40\u003c\/td\u003e\n\u003ctd\u003e200\u003c\/td\u003e\n\u003ctd\u003e385 x 270\u003c\/td\u003e\n\u003ctd\u003e580\u003c\/td\u003e\n\u003ctd\u003e7.9\u003c\/td\u003e\n\u003ctd\u003e1100-1800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalReact 220\u003c\/td\u003e\n\u003ctd\u003eVarioS 6\u003c\/td\u003e\n\u003ctd\u003e70\u003c\/td\u003e\n\u003ctd\u003e220\u003c\/td\u003e\n\u003ctd\u003e420 x 280\u003c\/td\u003e\n\u003ctd\u003e580\u003c\/td\u003e\n\u003ctd\u003e9.3\u003c\/td\u003e\n\u003ctd\u003e1400-2100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Reef Octo","offers":[{"title":"CalReact 140","offer_id":49942651273459,"sku":"CALREACT-140","price":1050.0,"currency_code":"AUD","in_stock":true},{"title":"CalReact 200","offer_id":49942651306227,"sku":"CALREACT-200","price":1185.0,"currency_code":"AUD","in_stock":true},{"title":"CalReact 220","offer_id":49942651338995,"sku":"CALREACT-220","price":1400.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2152\/8391\/files\/ClaReact-140.png?v=1784524638","url":"https:\/\/oceanreefsmarine.com.au\/products\/reef-octo-calreact-calcium-reactor","provider":"Ocean Reefs Marine Aquariums","version":"1.0","type":"link"}
