Guide Review - Red Sea Berlin HO Protein Skimmer

An adaptation of the venturi driven Red Sea Berlin Classic skimmer, the Berlin HO (Hang-On) is designed to hang directly on the tank or sump by way of its easily accessible inlet and outlet tubes, and because of its compact size, this model is ideal for the hobbyist that has limited space or who would prefer not to install or use a sump. This skimmer has been reported by some to require frequent maintenance to obtain optimum efficiency.
