+1, muh huh, etc. You have significant algae. Your nitrates and phosphates are not both zero.
I have seen this particular algae first hand survive at zero nitrates and zero phosphates, believe it or not. At one point I had reduced feedings and dosed vodka so much my corals almost starved to death. It hardly phased this stuff. In almost every other case that involved another type of algae I would agree with you.
I wouldn't say there is significant algae, the rocks in his pictures are quite clean. As for the flatworms, that's probably just an issue with the amount of flow. I am guessing that the algae hitched on the frag because I don't see it anywhere else in the tank.
As I had suggested before, forget trying to lower your nitrates etc just do whatever you can get it this stuff out of your system (tossing anything that has this algae on it). Whatever you do, do not scrape it off in the tank.
