Flatworm Exit - My Method

[jonnywater]

I was thinking of how I am going to approach this tomorrow. No one can seem to get in the nudis' that eat flatworms, so I purchased a bottle of Flatworm Exit. I was thinking of taking all the snails, my star, my conchs, my clam and all my fish out of the tank. Since the flatworms seem to generate 4-5 inches right above the substrate - I was going to drain my tank down to below my corals for about 25 minutes and add the Flatworm Exit. That way their "juices" really dont come into contact with anything. Then drain half of that water and do a change and run carbon and all that. Then drain half the water again, and do another change. That way I would probably kill off about 90% of them without damaging anything. Then I could fill my tank back up past the corals and get the rest.
Any thoughts? Good idea, bad idea?
I just dont know about some of the things though. I have heard that you need to wash your entire substrate and tear down your entire tank after you use this stuff. I only heard that from one person though.

Here's what I'd based on my own experience using FWE:
Siphon out AS MANY flatworms as you can prior to using the FWE. Leave all the fish, corals, and inverts in the tank.
Disclaimer: I'm not responsible for any inadvertent deaths, yada yada yada...
Dose the FWE at 2x the recommended dosage on the bottle. The flatworms should start dieing within 5-10 minutes. Grab a powerhead at aim it around the tank, between the rocks, and into the little nook and crannies to get the worms. After 30 minutes into the treatment throw in the carbon and do a 50% water change. Do a smaller water change the next day if anything still looks stressed.
I've done FWE treatments in the past and the worse side effect that has happened was my SPS corals lost color. All other corals and inverts were perfectly fine and I suffered no deaths. At the time I had no fish.
