Well from what ive been reading it sounds very much like my intended Rio 180 (40 x 20 x 16), dispite the fact that those measurments give me 55 USg (Cant be right surely?! The measurements are the same on each site yet the calculator says 207l? I know some will be lost by hardware but thats alot of extra!)...Anyways, as its only just over 3ft long it seems to be too short and everyone says 4ft such a shame, ive really taken a shine to these wicked set ups!
