Has the third treatment of Prazi shown to add any stress on fish in QT?? If not its a good thing! An (extra) ounce of prevention is worth a pound of cure, lol, as the saying goes...
I usually do just 2x treatments of 6-7 days, then water change, carbon and skimmer, and 72 hours later a second treatment of 6-7 days, after removing carbon, skimmer. If I need to do a WC in the middle of a treatment, I re-dose for the amount removed.
Glad to hear that they handled Cupramine!!! Thats super scary, as I've lost too many Dwarf angels to copper based meds.
If you dont mind sharing how slow the ramp up and the duration of the treatment was?
Thanks !
