Selling my calcium reactor because moneys a bit tight right now. It was run on a 125 gallon reef tank with stonys and softies. Thing works great and I never have had any problems with it. It can be run on aquariums up to 700 gallons and it very precise and can be fine tuned. It has the black older model pump on it now but i have the new yellow pump for it in case you want to switch it or whatever. Both pumps run fine and the yellow one is literally new. Also comes with 10lb C02 Bottle full and regulator with selonoid. Taking reasonable offers on price but its a pretty fair price for what your getting Its a 700$ reactor without the c02 bottle and regulator added in. Works perfectly. PM back on here or call 973 270 8866. Here is what the website says about it:
