/diy/ - Do It Yourself

Hello /diy/
Long story short: I want to upgrade my 55 gallon aquarium to a 75 gallon. The only problem is, the 75 gallon will weigh approximately 200 more pounds than the 55 when full of water, rock and substrate. The 55 is currently sitting on >pic related and I really doubt that it could hold any more weight. Hell, I'm surprised the old dresser can even hold the 55 that is on there right now! The dresser is "antique" (my mom got it when she was ~18 and she is like 60 now) and it sits on wheels.
Anyways, I am trying to come up with a design for a stand that can fit over/around the dresser so I don't lose use of the dresser.
The dimensions of the dresser are: 44"x20"x36"
The dimensions of a 75 gallon aquarium are: 48.5"x18.5"x21.125"
A filled 75 gallon aquarium should weigh approximately 785lbs. A lot of times, we estimate 10lbs/gallon but it usually weighs less, however, I would like to build something that would support 1000lbs.
