In the saltwater aquarium is essential to use a protein skimmer. This regulates the "evacuation" of albumin (protein), phosphates and other substances, prevents the growth of algae and increases oxygen content.

To complement the existing marin range, sera has developed two highly efficient protein skimmers that produce tiny bubbles and thus achieve excellent foaming level.

The sera marin Protein Skimmer 400 HO is the model that hangs and is ideal for smaller aquariums up to 400 liters that do not have a separate sink. It is easy to adjust and allows foam proteins with high efficiency in the saltwater aquarium.
