Red Sea Berlin X2 Venturi Protein Skimmer Information

Collection Cup with built in foam-view window

Patented window built into the side of the skimmer neck allows for accurate real time evaluation of foam production.

The Triple-Pass Principle

Red Sea’s patented Triple-Pass maximizes the water air contact time inside the skimmer reaction chamber stripping the aquarium water for even the smallest traces of organic pollutants, while minimizing the external dimensions and footprint of the product. 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
Venturi injector
  • NEW high air-flow injector design
  • Completely removable for easy maintenance
  • Max. water throughtput: 600 lph / 160 gph
  • Max. air throughtput: 200 lph / 50 gph
Hang-on-tank kit

Enables the Berlin X2 to be quickly and easily converted from in-sump to hang-on configuration, offering the user greater flexibility and customization possibilities. The hang-on-tank kits is comprised of quick-fit parts for user-friendly installation and maintenance.

Long term pollutant reduction

Tests have shown that over time the Berlin X2 is extremely effective in lowering the level of oxygen-consuming pollutants (COD/BOD) in the aquarium water.

How do we rate our skimmers?

The recommended aquarium volume ratings for the Berlin X2 have been calculated according the optimum turnover rate per aquarium type, as determined by laboratory test conducted at Red Sea. They are as follows:
  • Fish tank: 1 turnover/h
  • Soft Corals (LPS): 1.5-2 turnover/h
  • Hard Corals (SPS): 3-4 turnover/h

Comments: I have had the skimmer for a little over a year and I bought it to replace a cheap skimmer that I was using. The skimmer does a good job of skimming, however the pump sometimes freezes up on me. This in not from lack of maintenance, I regularly disassemble and clean the pump components. The motor is very noisy. I don't know if it is the way I have it mounted in the sump or not, but it hummms very loudly!!!

Comments: The idea behind the berlin x2 is awesome, but very very hard to regulate the foam and water mixture. I do not recommend this for beginners. :(
