I'm running a Bubble King Double Cone 200 with RD3 pump on my 150g (200g total) tank. It has a very heavy bioload with a Regal Angel, Purple Tang, Yellow Tang, Moorish Idol, a Potter's Angel, 4 Bartlett Anthias, 3 Lyretail Anthias, a Starry Blenny, Mandarin Goby, Diamond Goby, and 12 wrasses of various sizes, including my beloved Earl's wrasse!
Here she is before I gave her a vinegar bath...
I collect this level of gunk about every week. You absolutely can't see through it in direct sunlight.
I've been running my skimmer for over a year and a half without a hiccup. It's running at about 8" of water at 36 watts. Its seriously one of the most solid investments I have ever made in my tank.
Here's a video and some pictures of my tank
