Is tank on hardwood floors a bad idea?

[csnow]

I am moving into a new house with hardwood floors. I have a 55gallon tank that I want to setup as a reef tank (converting from freshwater).

Is there anyone that can share some stories or insight on placing tanks on hardwood floors? Will the weight cause dents/damage to the floor?

If it will cause damage, is there anyway to prevent this?

Thanks!
