I think the flatworm problem was another thread but the short version is:

The wrasse was eating them but couldn't keep up with the supply and I didn't have a very deep sand bed for the guy to sleep in so I took him back to an LFS. I emptied the entire tank to include all the substrate, refilled it, nuked it with flatworm exit which I thought did the trick. About a month or so later they started popping up again even though I had added no new livestock or rock to the tank. The only thing I can figure is that flatworm exit will not kill off eggs and this is why I will do a multiple application process in the future. Sort of like getting rid of fleas, you have to treat at least twice. Once for the adults and then once again after any eggs hatch.
