I recently got the biggest tank I have ever had to date- a 29 gallon. I also got a manufactured stand to go with it. Previously I had used strong tables, dressers etc. To my surprise the wood cabinet has a strong top rim but nothing in the middle! I figured the manufacter know what they were doing but as I filled up the tank sitting on the stand I kept waiting for the middle of the tank to rupture and go crashing to the floor. How is all this water weight supported by the sides with no support under the glass on the bottom? Will someone out there who knows the answer to this reassure me. I am still suspicious of this tank and stand. I know this is probably a stupid question but humor me. (Please)
