How high is the water level in the skimmer? Is this a brand new skimmer or a used unit? Has the pump/venturi ever been cleaned? How much skimmate is this unit pulling out in terms of volume (i.e. how often do you empty the cup)? There's nothing wrong with wet skimming really and I find most EuroReefs and similar style skimmers tend to wet skim more than, say, beckett style skimmers.
