Deltec MCE400 Hang On Protein Skimmer for Marine Aquariums

The Deltec MCE400 Hang On Protein Skimmer delivers professional-grade protein skimming performance in a compact, space-saving design. Built as the smaller sibling to the renowned MCE600, the MCE400 is ideal for reef and marine aquariums where sump space is limited or unavailable.

Capable of drawing 350 litres of air per hour, the MCE400 efficiently removes dissolved organic waste before it breaks down into nitrates and phosphates. Its hang-on design allows installation on the back of the aquarium or on the side of a sump, offering excellent flexibility for a wide range of aquarium setups.

Powered by an energy-efficient internal needlewheel pump, the MCE400 draws water directly from the aquarium and delivers the high air-to-water ratio Deltec skimmers are known for—often 2–4 times more air than comparable skimmers rated for similar tank sizes.
