Berlin X2 Protein Skimmers
- The Berlin X2 is the latest evolution of the popular Berlin range of skimmers, used by thousands of satisfied aquarists around the world since 1993.
- The X2 offers a 50% increase in skimming performance over the old model, while preserving its predecessor?s small footprint and compact dimensions.
- 50% increase in skimming efficiency over previous model
- Enhanced Triple-Pass reaction chamber
- Patented FoamView collection cup
- Super compact design
- Quick-fit inner parts for easy maintanence
- High performance pump included
- Designed for both in-sump and hang-on use
- Venturi Skimmer features:
- New high air-flow injector design
- Completely removable for easy maintenance
- Max. water throughput: 600 lph/150 gph
- Max. air throughput: 200 lph/50 gph
- FoamView collection cup
- Patented window built into the side of the collection cup allows for accurate, real-time evaluation of foam production.
- Hang-on kit included
- All Berlin X2 models include a hang-on kit as standard, enabling the in-sump configuration to be converted quickly and easily for hang-on aquarium setups.
- Red Sea´s patented Triple-Pass maximizes the water-air contact time inside the skimmer reaction chamber, stripping the aquarium water of even the smallest traces of organic pollutants, while minimizing the external dimensions and footprint of the skimmer.
- By forcing the water-air mixture along a circuitous route, the Berlin X2 achieves a total surface area equal to that of much larger conventional skimmers.
- Highly efficient skimming action
- Removes even the smallest traces of organic pollutants from aquarium water
- Super compact design
- Minimal loss of seawater

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.
