have been messing around with this stuff - it contains pine oil, a phenolic disinfectant which works as an endocrine disruptor. This is why it smells like pine-sol. Some interesting/boring reading:

From my basic observations, it will make monti eating flatworms release, and consequently die, but is ineffective on the eggs at the recommended dosage.
On a side note, I mixed up an emulsion of pine oil, added this to a dip and when using the concentrations indicated in the epa file, the result was quite opaque, and the corals did not respond well. I am trying lower concentrations, will report back with results.
