hmmm...
from what i have read on the product, i am pretty convinced it will kill the flatworms as you have found.
and it seems like a great product to have on hand, especially for you, or anyone else who has a quarantine system.

but my main concern, is when it is used in a full blown reef environment, and you're dealing with all the microfauna on/in the live rock and sandbed.

to what degree will the existing microfauna populations be affected, if they are at all. and can we curb the effects with aggressive use of carbon and waterchanges following the treatment.

fortunately, *knocks on wood* my flatworm problem is mild at best and is not severe enough for me to warrant the use of the product.
