Flatworm exit

[hurley]

I had the same issue recently, just a handful of red flatworms. Picked up some flatworm exit and used it as directed, except I almost doubled the dose. Worked great, vacuumed out the 10-20 dead flatworms that I saw, popped in some fresh carbon and did a little water change. All my corals and fish were great.

Its best to treat when you have only a few, if your tank becomes overrun the toxins they release when they die can be harmful.
