The patented technology (developed by the Julich Research Center of the German Institute of Technology) incorporated into the Red Sea Berlin Skimmer has resulted in a unique, compact design that is more effective than skimmers twice the size, removing low concentrations of protein that other skimmers can’t.
Features
· Triple Air Pass increases the contact time between the air bubbles and water, due to the patented "Air Return Skirt".
· Tangential Water Inlet causes turbulent flow and a swirling motion that increases the mixing action of the water and air bubbles.
· Removable Collection Cup & Inner Tubes for easy cleaning and maintenance.
· Optimal Compactness, without compromising the skimming efficiency. Performs as well or better than skimmers twice their size.
· Efficient Concentration produces highly concentrated waste without unnecessary loss of seawater, removing even the smallest amounts of waste material.
The Triple Air Pass Technology incorporated into Red Sea Berlin Skimmers` reaction chamber has resulted in a unique, compact and effective design, which concentrates the waste without unnecessary loss of water.
Turbo pump included with all Berlin skimmers.
Berlin Classic Turbo Skimmer
The Berlin Classic originally set the standard by which all other skimmers are measured. The original triple-pass design optimizes the contact time between air and water by length of contact. The telescoped tubes of the Berlin allow for a long contact time as the air/water mixture moves up and down the triple pass design.
The traditional venturi injector allows for a massive influx of fine bubbles while creating a turbulent storm in the bottom mixing chamber. This "Classic" venturi driven skimmer can be operated from an external or submersed pump for increased design options. The ozone resistant parts, optional carbon air filter above the collection cup and air return skirt that ensures that no air bubbles return to the aquarium, make these models ideal ozone reactors.
This skimmer design changed the world for the serious aquarium hobbyist nearly ten years ago and it`s just as effective and popular today. The Berlin Classic is still a great choice for most types of marine and reef aquariums.

Berlin Hang On Turbo Skimmer
The Berlin HO is an adaptation of the Berlin Classic that allows the skimmer to be hung on the side or back of the tank or sump maximizing space. Utilizing the same patented triple pass design the Berlin HO is one efficient skimmer. The unique design of the mixing chamber allows for maximum air/water mixing and the state-of-the-art triple pass hold the mixture together for much longer than most other skimmers to optimize the actual protein extraction.
The HO is capable of handling any tank up to 250 gallons and can be mounted inside or hung on the sump as well as the aquarium. This skimmer allows many options for the aquarist that has space limitations.

Berlin XL Turbo Skimmer
The most critical factor in protein extraction through foam fractionization (protein skimming) is contact time (the time in which the water and air are held together in contact with one another) in a homogenous mixture.
Contact time is critical as it allows the bubbles more time to pick up and remove protein and waste products.
Contact time can be measured two ways.
One is the length of contact, this is a measure of how long the water and air are kept together while passing in the chambers.
The other way, to measure by volume of contact. When injecting twice the number of fine bubbles and doubling the capacity for the bubbles to do their job.
The Berlin XL increases greatly the contact time between air and water by length of contact with its taller design. The taller design combined with the triple pass method allow for a much more significant contact time together.
