That's an awesome setup man , yes that's what the top of mine looks like with lights sat ontop , not sure about how tuff the glass is yet I think the sliders are 8mm but we'll find out in few more months when the jar hits 24" lol (ill be in the s##t if he breaks one )
One filter will do for clean water but you may have a problem with flow reaching the other end of tank (what filter you using ? ) you could always add a powerhead or wave maker to the other end , all my aros have loved faster flowing water plus it keeps them active and strong IMO
