Is 10 weeks fallow enough for ich?

[ReefKing101]

So my DT has now been fallow for 10 weeks today. Is this enough time to put my fish back in from there qt ?

Good question! I've heard 75 to 85 days as being the range. Back in the late 1970's there was a paper by some Japanese researchers that said 35 days was long enough....they were wrong (grin).

What fish do you have in QT and how are they doing? I generally wait at least 45 days for the date that the fish's symptoms went away before considering them "cleared" of disease.

I treated them with cupramine for 6 weeks at full strength to be sure. But even after a couple days the visible ich was gone
