Mine have ick and flake so I put all of them in qt I added 2 drops per gallon like it said and all fish are eating and seem better how long should I leave them in it?Personally I only observe in QT, I do not treat unless I can diagnos an illness. Time in QT varies dependant on a few things.
A) if the fish come from a LFS, then observation for 7-14 days is all I do provided they eat well from day one, act normally and show no signs of diease. For the first 7 days, I use 1.020, then for the second 7 I move salinity upwards to my target 1.025, .001 per day.
B) if the fish is shipped, I follow the same regime, but extend QT to around 30 days.
Only when signs of diease are evident do I use any meds as the long term effects of these can be problematic.
Thank you have have all of them in copper safe and they all seem to be doing well they are eating I didnt know how long to treat them and my dt is fishlessIf your fighting Ick, I do not know the success in using Formalin only cupramine and hypo in the past.
That being said, if the medication is working, I go a full 21 days after the last spot is seen before I declare the fish clean of the parasite.
That being said, I leave my DT fishless for 72 days, before I declare it Ick free
