I just killed EVERY SINGLE FISH in my tank with FWE this week.... BE SUPER CAREFUL. In retrospect, I would have removed the fish prior to treatment.

I did everything according to the book with the treatment. I have used FWE in the past several times without much issue....the only thing I can think is there were a lot more worms than before this time around, even despite my siphoning what I could out prior to treatment.

Frankly I am having one of those "why am I doing this hobby moments" today...as I look at a line up of dead fish bodies sitting next to my tank. Not to mention a bunch of really ticked off corals.
