Guinness;538043; said:AGA's 48" tanks are 18" tall. If your only going 12" tall, I think you'll be ok. I would make sure that the bottom is fully (i.e. not just the edges) supported with thick ply covered with stryo to provide even pressure. Also use cross bracing in both directions on the top. I'm no engineer, so this is just my .02.

Especially on the bracing accross the center of the tank. If your still concerned make a frame around the top and bottom.
