Hi, This is what I do with the aquariums I still use:
It's a metal baker's rack, you can get them at most home improvement stores (they are kinda pricey, around $100). My b/f got lucky and found 4 of them at goodwill a few years ago for $20 a pop, we use them all over the house. You do have to leave some room to get access into the aquariums, and in my case, I use larger logs in there, so I had to leave clearance to get the logs in and out. Good luck!
