Count me as another happy SeaClone owner.
The thing to keep in mind with the SeaClone though, is that they are extremely overrated... there's no way I'd use my SC150 on a 150g tank, but it works great on my 55g.
The newer model SeaClones have also been somewhat redesigned so that the problems experienced with the first ones were remedied. I tried the airstone trick, and it put out waaaay too much foam.
I'm also running mine as an in-sump skimmer, though I see that Craig is using his with the downtube... you can see from the photo I attached that it gets a nice wet, dark skimmate, which from what I've read is how you want it.
Most people like to berate the SeaClone, but I've had nothing but positive experiences with it. I'm not saying that the Remora is a bad skimmer (in fact my second choice for a skimmer was an Urchin, the in-sump version of the Remora), just that the SeaClone does a good job.
The piece of plastic gutter attached to the downspout of the skimmer is to redirect the water back into the sump without it splashing all over since the skimmer sits about 12" above the water level in the sump... just in case you were wondering.
P.S. I should also mention that I just cleaned out the skimmate cup yesterday afternoon... the skimmate it's collected is from the hurricane treatment I gave the tank last night and some of the phyto/zooplankton I added to the tank this morning... it's doing a nice job pulling gunk out of the water. I usually have to empty the cup once or twice a week.
