Euro-Fil 1 The Euro-Fil 1™ "Berlin Method" filter sump is the perfect starting point for those who wish to pursue the German, Mud, or Eco-System methods of coral reef filtration.

The rugged acrylic construction is durable and its simple design is easy to install and maintain. Note, models 182, 240, and 360 have two each inlet bulkheads.
