I am about to move my nano to the living room. I have decided to remove the CPR Fuge since it takes up almost the entire back of my tank. This is the medium size. I will have to measure the dimensions and post that as well. I have ran it for a few years. I made a lexan top to protect the light I made for it. It will include The lexan cover, light, reef rubble, pump, and a large amount of chaeto. It is everything you need to start using it. $70 I will post some pictures I took with my phone.
