PLEASE PLEASE HELP!
Im freakin out.

I have never had to use FWE before so this is my first experience with it. I followed the directions perfectly!

My set up.
175 gallon display / 100 gallon sump

I made up 100 gallons of salt water for water change.

Carbon reactor. BRS ROX carbon.

Friday night (24hours ago)
I siphoned out as many as I could see prior to use. Within 60 seconds of application, the flatworms began to die. I siphoned a while,then replaced
with fresh, repeat, repeat,repeat untill the entire 100 gallons of waterchange was complete. 95% of the flatworms had been removed. Fish and corals all looked good for the rest of the night. this afternoon when the lights came on everything looked great. I cound see a few scattered worms...but very few. Fish happy, eating well tank looked great.

Up untill just a couple of hour ago...all was well.

All of a sudden most of my fish are hiding in the rocks. Mostly tangs. very lethargic and not eating. (if I didnt know better I would say my hippo's eyes were clouded)
Powder Blue,
Yellow,
Hippo,
Blonde Nasso.
Normally very active, especially when I approach.

All my corals are closed!!!

I just tested, everything looks ok.
PH 8.3
Amonia -0
Trates -0
Trites -0
Ca - 350 (Actually a bit lower than normal)
Mag - 1250

The only thing that I was not certain about was the carbon. I AM running a good bit more that normal. Just wanted to fight the toxins. Probably double what I would normally run.

This has all happened within the last few hours!!

ANy help greatly appreciated!!
 
There may have been many more flat worms that died that you couldn't see.
I'd mix up some more water, do a wc and refresh the carbon.
