So I got some flat worms from a frag that I bought in put in my display tank. They started out just as a little amount so I got a six line wrasse to help out cuz it wasn't that many. He did the job very well but it was like over night they got out of control and the six line isn't even putting a dent in these things! So clearly it's time for me to do something. They r not bothering my corals at all they aren't even on them they r just all over the glass sand bed and rocks. They aren't bothering anything but they r just so ugly that I want them gone I'm tired of looking at them. But I've heard horror stories about flat worm exit basically killing everything in people's tanks. I've never used it before and I was wondering if anyone could give me some feed back on their experiences with it? Also if u could give me a walk through on how to use it and how much of a water change to do after and stuff. Thanx in advance!
