Came home to a huge puddle around the base of my 70G. My Eheim 2073 (G90) was leaking. For what this thing cost me, I'm not too happy about it. I bought it about 1.5 years ago. My XP3's never had any problems and I had them up and running for twice as long. Thank God I moved the tank into the garage a few months ago. If it had ruined my newly refinished hardwood floors, Eheim would be paying to have them redone.
