I've been thinking about this for a while.

This is a good read.

Then I started looking at various molluscicides. One jumps out at me, Ferric sodium EDTA. It's a type of chelated iron, and while highly toxic to arthropods, that may be a price we have to pay to win the war.

I am wondering if it's function in a saltwater environment is such that the concentrations needed to kill the vermatids is low enough that fish and coral would be unharmed. It reacts with the copper based compound in the blood of molluscs.

Another approach I was considering... In the study above, it shows that the brooding females lay egg sacks that swell and intake water. I'm wondering if a combination of manual removal and low doses of iron can halt reproduction of vermatids all together and then manual removal over time can rid them.
