OK sports fans, what size glass has everyone used in constructing their baffles? I am trying to come up with a removable baffle(s) utilizing weatherstrip at the edges. 1/8" won't work because it flexes and blows out. The reason I want them to be removable/moveable is due to the 150 tall tanks stand being so short and the side of the 40 breeder in the cabinet doesn't allow much clearance between sump and top of cabinet. If the baffles were moveable, then I could take them out and allow some room should I need to work on anything (replace pump in skimmer, etc.). Any thoughts suggestion? Thanks, H
