Hang-On Refugium is too heavy for a glass tank?


have anyone tried to put a Hang-On Refugium to the back of a glass tank? My tank is 30 gal with glass made. i saw there is a nice hang-on refugium which weight 12 lb. i'd like to add it on my tank. (25-1/2"L x 4-1/2"W 12"H). however, if i fill in water and sand to the refugium, will it be too heavy for glass tank?
any reply will help, thanks!:notsure:

Maybe you could put something under the fuge to support the weight. Maybe stack up some blocks or something...
