Flatworm question

[jcs11236]

I havent bought any corals in a while. i picked up a few different pieces and one of them must have had some flatworms. i dip all my pieces so not sure what happened. i noticed them a few weeks ago on my glass. i decided to catch a few today and check them out. they dont seem to look like the Red Planaria flatworms. i dropped 10 drops of fwe into a 50 ml and the fw are not reacting to the fwe.? is this a different kind of fw? not sure what to do if they are not dying with fwe

they look similar to these but they are dark-like gray/black

i had a big fw problem when i first introduced live rock to new tank. i bought the fwe and used according to directions. i didnt have any livestock to be concerned with so i took the advise of many people here and used more than directions called for while also siphoning out some. it worked after 2 bottles.

do you have livestock in tank? if so, i would go by directions when i bought med, lfs suffested using carbon too...but i got different input on the boards and removed it. good luck
