FOR SALE: I have a GEO’s Reef calcium reactor, model CR1218. It works fine, and everything is included to get you going, other than media. I used it on my tank for about 6 months. It will hold 75lbs of media, good for tanks between 600-1500 gallons. Retails at $1498. I will throw in the CO2 bottle and CarbonDooser electronic CO2 regulator for free. Asking $1200 out the door. Buy covers the cost of shipping.
