Is that a real wood floor or tile that looks like wood?
If it's a real wood floor I'd want some serious water control under and even 2 or 3 feet out in front of the tank. And a liner under the sump, but the Red Sea sump fits so tight you really can't... which is why I got a CADlight system instead.
Seriously, a friend had wood floors and over the years they became a HUGE mess due to small spills and splashes.
