Makes sense though...HOB's discharge at the top of the water, which would disperse a lot of the waxy crud. I personally don't have any real issue with the stuff because I figure it's a product of a healthy tank, right? What does bug me about it is that I have water lettuce, duck weed, and hydrocotyle that likes to breathe, and looks simply awful with that nasty film surrounding it.
