I prefer it on the wet sideI think it will remove the waste a little faster. I just do not want it too wet because it sometimes causes a full dump/overflow of the cup.
Wet skimming may pull out more organics than dry, depending on what you do to adjust it from dry to wet.
But it is less efficient in terms of salt water consumption, if that is a concern.
i try to change 1% of the tank volume daily, and I strive to do that by skimming, when possible.

Wet vs. Dry Skimming
--------------------------------------------------------------------------------
Foam draining is a critical stage for most skimmers. One problem with drainage is that some organics are washed away with the draining water. There is always an equilibrium between organics in solution, and those actually attached to the interface. As water continues to drain, some of the organics are lost. Further, as some bubbles pop and their organics are redistributed into the nearby water, the local concentration of organics in the water between the bubbles in the foam can rise to concentrations far higher than are present in the aquarium. For this reason, the most effective skimming, in terms of total organic removal, comes from removing somewhat wet foam, rather than waiting for this same wet foam to drain prior to removal. The primary difference between wet foam, and drained dry foam, is that additional water and some organics have drained away. A dry form is more efficient in terms of the amount of organic removed in relation to the water volume, and all skimmers and their potential adjustments strike some balance between removing more water and slightly more organics, or less water and slightly fewer organics. Perhaps a careful analysis of different types of skimming will, in the future, show this expected result experimentally.

Thank you Randy I just bought a CSS 65 used and cheap for my 55 gal tank and I am running it in my sump.It skims wet for the most part and comes out looking like that last glass off tea in the pitcher with the tea particles in it.After about three days i have a half a cup or so not bad I would say.It might skim more after i get the hang of it.
Randy, are you saying you skimmer collects over a gallon per day?
Even when im wet skimming i dont take that much out in a single day. Interesting.
For a period of time when first cleaned, it easily skims out over 3 gallons per day, which is about 1% daily on my system. In order to limit it to about 3 gal per day, I throttle back the Iwaki 55 RLT that supplies the ETS 800 Gemini skimmer. Over a few weeks it skims less and less liquid as it gets dirty, and I increase the flow. Eventually, when it can't keep up to 3 gpd at full pumping, I clean it and start over again.

I used to skim so that it looked like Chinese Green Tea, now when I skim it looks more like wet guacamole.

I don't want to take a chance of overfeling the cup so I skim on the dry side

That is two days,maybe a little less, on my G3 skimmer.
