I think I would suggest a similar fix to any Rio-180 owners to prevent issues.
The aluminium bars cost £2.90 each, 4mm thickness, around 60mm wide, 375mm length, then there are two galvanised steel brackets 60mmx45mm from any hardware store/ebay and aquarium glue (from Juwel). It is glued on the inside of the glass and above the top trim and the brackets are not visible on the outside. Even on the inside the shiny aluminium bars look beautiful.
Assembly: first glue the brackets on the glass on either side of the central strut. Use electrician's tape to hold the brackets in place until the glue sets. There should be about 2mm of glue between glass and bracket. After a day or so place the aluminium bar over the brackets secured with more glue. For good measure I also drilled plenty of half-way-through holes on the aluminium bar ends where they attach to the brackets to create extra surface area for the glue to take purchase on.
Leave for two days to set.
Fill with water and watch your precious fish die as they munch on the still soft glue...
