Just want to add, your main display also have to fishless for 6 weeks to 8 weeks. Inverts and corals are fine. Ick will die off in the display without a host.
the display was a 90.
i was young and foolish and didnt know better. the ick came back cause i dont think it was completely eradicated. i realized ick is much more than what u can see with your nake eye. ick in some ways is like a cold n cancer.
just qt'ing the fish isnt going to solve the ick problem in the tank, any of you use uv's ? i dont have a problem in my tank but was thinking of putting one of the one's i have on my tank and running it on a timer for a couple of hour's a day
