Ive got a 46 gal bowfront from Aqueon and absolutly love it! But the stand it came with makes me nervous. It sure does not look like it could hold 400 pounds. Sure, Ive had the aquarium on it for a couple years already and if it was going to collapse it probably would have already, but I'd like to "beef" it up just for some peace of mind. Anybody ever done something like this before?
