Not again!!

Is this red planaria? Sorry, best pic I can do with an iPhone. I treated my 30L Nuvo with Prazi 3 times and couldn't kill them. Yesterday I broke it down and dipped every rock and coral, then set it back up. All day project, but I figured it was the only thing left to do.
Today I find these.

That looks like something else. Below is a pic of red planaria.

Well, they appear to be SOME kind of flatworm. I'm so disappointed they survived 3 prazipro treatments AND the dip. After I posted I put one drop of the dip into the container and they all died. There were a lot in my tank, but it looked clear until this afternoon.
Is there anything else I can try?
