Agreed, lots of threads on RC about treatment. I have a few loooong posts there.
Here it is in brief,
I have fought flatworms for the last couple years. Treated twice with Oomed. My fish got sick from the flatworms toxin, when they died. BE very careful. For whatever reason, when I started my new tank, I still had the little %&^#^^&*.
****** I AM NOT SUGGESTING THE USE OF QUICK CURE, JUST RELATING MY EXPERIENCE>BE VERY CAREFUL******* {LIKE SOME OTHER PRODUCTS, IT CAN TURN SILICONE BLUE}**************
My lfs friend tried some Quick Cure, {its a freshswater ick treatment}, in one of his tanks. It wiped out the worms. The corals closed up for awile, but since recovered. Never seemed to bother anything else.
I got so fed up fighting the flatworms and "waiting for them to go away naturally",

, I figured what the hey. Also my frags were still small enough to remove from the rock.
This time however, I removed everything in my tank. Some rock, the corals, inverts & fish were placed in one tub. All the rest of the rock, {several hundred pounds}, was placed in two other tubs. I then removed all my GeoMarine crushed coral bed and cleaned it in fresh water. :shock:
The two tubs of rock, were treated with Quick Cure. The empty tank water was dosed also. My large brittle star was still in the rock tubs, along with some snails & crabs. Never fizzed them what-so-ever. Along with the dead flatworms, I did see some dead pods.
I then replaced some gravel, only an inch so I can clean it,{flatworms favorite home}, plus some deeper and a little fine sand in the back, for the leopard wrasse and conch to hide, if they wished.
I then shook the be-jeebers out of every pice of rock, and built the reef again. {some still remained in the tub, w/livestock}. I then again treated the tank and rock, :twisted: {I was going to get them this time},

. All this time I had icecream buckets sitting on the braces, full of floss, being fed with pumps to clean the tank. After another day, I added some carbon and polyfilters to the buckets to remove the Quick Cure from the tank. At this time, I also treated my overflows, which are mini refugiums.
After all this I turned to the tub of critters. I had made a bucket of fresh water fo dip. Same ph & temp as tank. PTHHHHHHHHHHHHHHHHHHHHH, {I will explain that later},
Each piece of rock was treated in a bucket of Quick Cure treated saltwater, then fresh water dipped for 15 sec. {swished}. Some of these rocks had sizable colonies of monti digita. My large 10 year old bubble and cup corals, were also treated. I dipped the cup in both, but only the base of the bubble in Quick Cure and then all in freshwater.
All the sps frags were freshwater dipped only, as "its supposed to be safe for the corals" and I did not trust the Quck Cure with them.
Then the tub of water, with the fish & inverts still there, plus my skimmer running a full bore, was treated with Quick Cure. After this, they were placed back into the tank. All pumps, calcium reactor, and anything else, were also treated. Cleaned out the sump, put all fresh saltwater back in and started it up. I had a large bucket in there, under the overflow pipes, full of floss, carbon & polyfilters. This was run for a couple weeks.
RESULTS:
A month later, no flatworms yet.
The Quick Cure, seems to have bothered nothing. Never lost a snail, fish, worm, invert of any kind.
HOW &^%*&&$#^@ EVER, the fresh water dip, that was to protect my sps, killed them all. They all bleached and died. :x :x I amy as well just dipped them. I lost several acro frags, a couple brown digitas, one ofthe green digita, a monti cap frag, and my beautiful table acro frag.

{thats me bawling}. All my other corals were fine.
