Aqua C EV-120 Protein Skimmer

[Fishward]

Hi
has anyone got any experience with this style of skimmer?
theres a bit of an outline on how they work at this link http://saltaquarium.about.com/od/pro...skimmer1_5.htm

any thoughts or tips would be awesome.. im in a bit of a bind and only have about 22 inches of clearance in my stand, so im in the market for a short, effective skimmer.
