I am moving a 210 gallon fish tank (7*2*2) from 1 room to another 30ish feet then back 40ish feet once tile is layed. I am trying to get help from 1-3 other people most likely it will be 3 people including me. How can I move this 500 pound thing. I am thinking about getting 2 furniture dollies and putting it on that and moving it. I want as little holding onto the tank as possible the person who moved it for me said it cut into his hands and the longer its held the higher chance it is of being droped.
