I would use gallon jugs and put 30 gallons of water in it at one time. And then let it sit there for a hour or two and then put another 30 gallons in it. And fill the tank up half way one day and then fill the rest up the next day to see how the stand and tank along with the floor react to the weight of the 220 on it.
Did this with my 75 gallon fish tank when it was sitting on a old 1920's dresser.
