Here is a picture of the inside of my "in tank" surface skimmer. I don't have a sump and this thing skims the surface to remove the thin film that accumulates there. It also functions as a overflow as It feeds my HOB protein skimmer.
This is a view from inside after I removed the bottom. It is almost completely filled with tube worms and amphipods. The tube worms grow from the sides and go all the way to the center almost stopping the water flow. These tube worms I would imagine are a very effective filter and water purification plant. I am not sure what they would remove but I imagine they feed on any microscope life including bacteria. In this picture, much of it looks like wet cement, thats because I had to break a lot of them to allow more water to flow.
I love this stuff.
This is the unit from the side. I don't remember how old it is but I guess it has been there for 12 or 15 years.
