Flatworm Exit

[Randrew215]

I know that this product is widely used and has been extensively reviewed, but I thought I would add my experiences and see if the way I administered it was consistent with it's typical usage. I did not siphon out flatworms before hand because I could only see about eight of them (this was more of a nip-it-in-the-bud administration) and I wanted to be able to see when they died.
I have a 90 gallon tank with a 29 sump and used 90 drops (slightly over what is recommended). Flatworms died within minutes. Also, my brown powder tang became immediately stressed and his colors washed out. A few brittle worms also fell as casualties and my orange torch retracted completely. All other corals, clams, fish, and inverts seemed fine. I kicked in fresh GAC after about 10 minutes because the flatworms I had been watching were dead and I didn't want to further stress the tank. I then changed 15 gallons water that I had at the ready.
Orange torch is slowly coming back out and brown powder tang is slowly coloring back up (both still look a little [profanity], though). It's completely possible that I had way more flatworms than I knew, but is this sort of stress response typical of what others have seen? And should I be prepared to change more water?
Thanks,
Andy

Your experiences seem about par from what I've heard and seen first hand. I would change a lot more water though.

my experience and recommendation reguarding flatworm. remove everything you can that you love in your tank into a QT or a friends tank and +1 on a bigger water change. Flatworm exit will, depending on dose and many other factors kill other things than flatworms.

My experiences has been that all star fish have been affected and special brittel starfish and serpants. No fish or coral have been affected and most inverts seem to have made it but starfish are a different story, beware....

I agree with Tad....water changes are very important afterwards. The right way to kill the flatworms would be to get them a few days later or so with another dose since they hatch eggs / incubation cycle too. But in your situation with the affect it had on the tank, you might want to wait a week or two before doing it again but redosing flatworm is going to be the sure way to get rid of them affectively.

Good luck

FWIW, when I dosed my 90g I did two 35-40g changes on it, one the day of, one the next morning.

Just got back home. Thanks for the feedback/advice! Will do a larger water change tomorrow to be prudent.
