Just want to share my experience. I have a pretty bad infestation of red planaria in my nano. It was my own fault, the eggs came on a Zoa frag. I dipped and killed the living ones, but the eggs made it though.

Today I did my 3rd and final treatment of Flatworm Exit and I’m glad to say that I have 0 flatworms coming out after treatment. I probably could have gotten by with just 2 treatments, but I want them gone!

The first treatment was 3 weeks ago. I ended up having to triple the dose to get them to die. I did treat with carbon about 2 hours after they started floating and did a 20% water change the next day. The only negative thing that I noticed was the zoas were upset and the cerith snails were acting weird, laying on the bottom out of their shells. After the water change everything went back to normal.

The 2nd treatment was a week later. This time I only had to do double the dose. There were still a ton of baby flatworms floating around. After about 2 hours I treated with carbon and did another 20% water change the next day. The zoas were mad and the ceriths were acting the same way. Everything was back to normal after the water change.

I did start to notice that my anacropora, both the green goblin and the goldenrod, started bleaching at the base and moving up over the days. I also have a tiny frag od sunset montipora that lost all of its red color and the green polyps turned really light green. No other corals were affected.

Today I did the 3rd, and hopefully final, treatment. I did the recommended dose and nothing came out. So I went ahead and added a double dose, still nothing. I assume that they are all gone now!

The funny thing today is nothing is upset? The zoas are still open. I’m not sure on the cerith snails since they are all buried in the sand. The montipora still looks horrible and the anacropora continues to bleach. I’m hoping they pull through, but if not they were small frags so it’s not the end of the world. All other LPS, SPS, and zoas/mushrooms look great!

The third time nothing was upset because it isn't the chemicals themselves that were upsetting your corals/invertebrates, but rather the mass release of toxins caused by the death of the flatworms.

It is actually a well documented phenomenon, and why there is a strong recommendation *not* to use Flatworm Exit on heavily infested systems, but rather to manually remove what you can to reduce the risk of a full blown tank crash.

I have 2 close friends that had a heavy infestation, both of which I warned how critical it is remove whatever they can before starting the treatment, needless to say - they shrugged it off and both ended up experiencing a horrible tank crash. Most of their fish were dead within a few hours, some coral died, and everything else was extremely upset and had to recover for months after the incident.

Flatworm Exit is an excellent and effective treatment - but it needs to be used very carefully.
