Flatworm exit kills? stomatella snails

[jayelblock]

I used flatworm exit in my 10g tank at 2x recommended strength. After about 1.5 hours, I got nervous and did a 2.5g water change and ran carbon even though some of the flatworms were still alive. My stomatella snails came out during the dosing period, which was unusual because I typically only see them at night, then retreated to the rocks and I haven't seen one since.

Has anyone experienced stomatella death after using flatworm exit?

Does this "flatowrm exit" contain copper? That is a common invertebrate killer. It works against worms, but of course it works the same way against snails, crustacea and many other invertebrates which have haemocyanine instead of haemaglobine in their blood.

Here a Marc Levenson gives a report on the product and says its important to remove as much flatworms as possible manually before using the product: http://www.melevsreef.com/flatworms.html

Actually, I had very few flatworms in my tank, so I don't think flatworm toxicity caused the stomatellas to die. I am depressed that they are gone--I loved to watch them zip around the tank at night.
