This is the model. The pump is a year old recently changed all fitting were recently changed. Comes with co2 tank, regulator, still has gas, and basically it's running very well. It can be run in out out of the sump. 375$ OBO.
Obviously price on net is just for reactor not the rest of the things you need to run it. I can even help you set it up if you have beer and work around my schedule and don't live next to eMac.
I don't have clean pics because I'm still holding polyps for some folks and some Lps and won't fully take out till I break it down or sell it.
