one of my rio 400l tanks sprang a leak and ruined the stand, however I have a stand for a 450 vision (bow front) the tank does fit but I have an over hang as the tank is square and the stand is bowed, the overhang at the largest point (corners) is about 8", it fits fine lengthways and front to back its just the 2 corners I get the overhang on. Will it be ok to use as I really need to get it set up and just cannot get another 400 stand (in my price range)
