my reef creation cr-2 calcium reactor f/s

[CoralBeauties]

Very nice twin chamber calcium reactor for sale.  I built a larger diy reactor and am no longer using this one.  It worked great but after adding a 100 gallon frag tank and added a lot of coral it isnt keeping up with my alk needs without adding liquid alk.  Comes with mag 5 pump.  Items needed will be a co2 tank and regulator/ supply pump and a needle valve for the drip rate output.  I used a ph probe and my apex to control the co2 but could be run without it.  Sells new for $499 without a pump.  Just looking for $175
thanks
