I did the same thing. Seems to work pretty well, but I did it when I first got the tank so I am not sure if it did any good or not. Another thing I did was make a small stand to place under the stock skimmer to raise it out of the water a little more. It has seemed to make a big difference in the quality of the skimmate. Lastly, I removed my K2, K1, and K nano, and replaced them with a Vortech MP20. Since changing I have noticed a huge difference in my coral and fish activities.
