A little help

[atf72]

I found three of these large flatworm-looking creatures in my frag tank and was looking for some info about them. I would appreciate any help. Look at about 12:00 on the photo.

Thanks

They are little bitty and white-ish clear. They look alot like the first Acoel flat worm in this link

If you scroll all the way down to the bottom, it is the first one in the row of three with only one pic below it. Now, their little dots in the middle are white not red though...

So basically I have to pull everything out of the tank to treat for them because if I have a large die-off they are going to poison my tank...*shakes head and looks generally disgusted at the aquarium* After I treat, should I run a lot of carbon or what? I may not be able to take everything out so should I just dose a little at a time or??? *shrugs*
