I have a jbj nano hqi with a new bulb still in box just took it down last week the tank works great only thing is in summer I guess because of heat build up it would cause my mh bulb to go out when too hot but now that winters over you should be fine askin 250 with an aqua c remora hang on back skimmer and I have an oceanic pump I used on that skimmer or 200 without the skimmer
