I live in a Ranch with a finished basement. I would like to add a 220 gallon tank in my den which is the first floor of the ranch, and has standard hard word floors. I always hear of the risk of adding a large tank to a second floor but this is a first floor. So my question is will this work? Does any one else have a large tank on Wood floors. All of my other tanks are on a Concrete slab, so I am a little nervous about adding huge tank on wood floors
