I am in Bonita Springs, near Naples and I am running one. It came with a used Tank I purchased about 2 months ago. It was a well established tank and the only thing I did when I set it up at my home is use new water. It only skims about 1" of skimmate every 3 to 4 weeks, but it is super nasty. I would like it to skim a little more agressively, but I have it set to the max, and thats it. I must empty the cup on my other skimmer (in another tank) evey week, but the skimmate is much thinner. I am still undecided on the Euro-reef. I was expecting a nearly full cup every 1 - 2 weeks.
