Wondering if anyone has had any experience with Bubble King Skimmers. I saw a couple at the Marine Aquarium Expo on display but not actually running. They look really hi-tech and are expensive but as long as I am upgrading/going external, I want to look at all my options. I have seen a couple of pics online of the internal skimmers and on you tube but nothing with external set up. There is not a whole lot of info on these online as with most European products.
