I have this used sump that I never got a chance to use. Its the CLF1 Compact model. http://www.lifereef.com/berlin.html Size: 24" x 13" x 14" 2 x 1.25 holes for external pump or drain. 3 x probe holders 2 x float switch holders 3 x AOT holes 3 x media reactor Good for up to 120 gals I'd like to get $100 for it and need to sell asap. I'm moving and don't want to take it to storage. Please let me know if you have any questions.
