Killing flatworms in live rock

[christyf5]

Hey guys,
So as most of you know I got all new live rock and sort of restarted my system (really bad hair algae problem that I just couldn't deal with anymore as well as moving to a new house). Anyway, the old live rock that I had was absolutely covered in hair algae. I put it in a rubbermaid tub with a powerhead and a heater and all of my cleanup crew (I really didn't know what to do with them during the cycle). Anyway, I just sort of left it to do its own thing hoping that the algae would just die. Well it did. Either that or the cleanup crew were so hungry they weren't as picky about what they ate.

Well the rock looks mighty fine and I am severely tempted to put some of it in my tank as it is covered in purple coralline algae of which there is precious little on my new rock.

Anyway, to the point here. As I was taking down my tank for moving to the new house I noticed several colonies of flatworms in all four corners of my tank. None of my corals had flatworms on it and as for the rock well I didn't look too hard as I was kind of ticked at the time.

So, what do I do?? Should I assume that the flatworms are in the rock too? Can I give the rock a quick dip in freshwater? I realize that will kill most of the beneficial bacteria on the rock but I really just want the rock for the coralline algae. Will this kill the flatworms or does nobody know whow to kill them. It was suggested to me to put the rock out to bake in the sun for a week but quite frankly after paying :eek: $11.98/lb I would rather not completely destroy the rock (life-wise) if I don't have to.

Suggestions, comments, concerns????

TIA
