I'm moving into a new house and I'm going to put my tank in the finished basement. The floor is some kind of tile but it's really uneven. The pic attached isn't that great but you can see what it looks like. I'm thinking about making a form and pouring concrete over the tile to get a perfectly level area for my reefer 450. Anyone have any advice or other ideas ? This is my first house and the first time I can really make a space for my tank that is going to be perfect so I really want to do it right I don't want a bunch of shims
