I haven't tried the Lugols or the Interceptor in a dip yet. The Interceptor cleared my tank though.
Those that tried to Lugols for a dip was it at the strength that Eric has posted to use? He claims it will only work if its at that strength. Anything less and some will live.
"Ordinary 10 drop/liter Lugol's is basically worthless, too, but we used 5-10ml liter for times from 30 seconds to 10 minutes. At five to ten minutes, the 5ml dosage stressed the corals, and they had some bleaching. The 10ml dosage was worse. But, at less than 5 minutes for the 5ml dosage, and 2-3 minutes for the 10ml dosage, all corals tolerated it fine, no bleaching, and 100% kill of bugs. The vast majority had died and turned black, falling to the bottom, within seconds. I pipetted a few bugs off the coral and put them directly into a dish with that strength Lugol's under a dissecting scope and they went catatonic almost instantly and were dead within 30 seconds."
Since I haven't personally tried either in a dip, I am simply looking for some more information on what you did exactly.
I find it odd that Eric claims the Interceptor didn't work for him until it reached the 24 hour mark but others have used the 6 hour length and claim it works. Hell. I've seen it work in my tank. At least I haven't seen a bug since I treated.
Then there are those that claim the Lugols didn't work, yet Eric claims that works well at a very high strength.
If I had red bugs on an acro currently, I would love to try the Lugols and see for myself. I think the Lugols dip would be better for a dip for many since its easier to get, and it shouldn't kill those cute little crabs. The Interceptor seems to be the only option for a whole system though.
Looking for options.
