Can you identify this pond scum?

We currently have some well, crud, covering certain areas of our pond, and we need to get rid of it. Joshua and I have been joking that we need to get some asexual carp to eat this crud. Dad is going to take the pictures to the OSU-Extension office. Preston's dad suggested throwing some sheet rock into the pond. Apparently, the lime helps kill the crud. We are open to any suggestions. Frankly, I blame the turtles.

It did not really gross me out before, but the little things poking up out of the water look like slimy fingers. And with that, I am officially grossed out.
