Ridding Tank of Brown Flatworms

[dareefguy]

I used flatworm exit aswell. It worked well but also killed my sea hares. This is what I blame for loosing all my fish, which chain reacted to kill some corals with the spike that came from that. To top it all off I never did get rid of all the flatworms. However they overpopulated themselves and used up whatever nutriant that they live on and tapered down to decent numbers. Now I don't bother them and they don't bother me. Although since I added a velvit nudi, but I think my sixline killed it.
