anyone ever use flatworm exit? i have a bad infestation and need these things out!!! really didnt want to use chemicals but think its my only option.

I have some experience to share with you. I had red planaria in decent numbers. I would siphon them out with water changes weekly but the numbers kept stable. I decided to try FWE. I had 30 gallons of fresh saltwater made up (about 75 gallons of total tank volume). I put the FWE in and within minutes more flatworms than I ever thought I had were floating in the current. I put mesh over my MP20 to collect some of the dead and had 2 syphons going into nylon socks in my sump which I changed every couple of minutes to ease the toxins released by the dead flatworms. After an hour or so I started running carbon and did a WC. It felt like a success.... fast-forward to the next day, my jawfish and royal gramma both had some weird coloration going on but were otherwise eating and acting normally and some of my SPS lost color, not browned out completely, but lost color. About 5 or 6 days later both the jawfish and the royal gramma died. The worst part about this is that there are still flatworms that I am guessing burrowed in the sand. I hit them again with FWE and didnt see many dead ones at all, didn't even do a WC after that for 2 days to ensure proper death. Two days after that I came home to find one of my two blue/green chromis dying with the same weird color loss, I am not sure if they ate the flatworms that were dead or what happened.... I still see flatworms in my tank so I am just going to hope my melanarus wrasse goes to town on them or I will have to live with them. Not the worst thing in the world and I would rather live with them than kill anymore fish or mess up my corals. Can't tell you what to do but this was my experience.
