Hi, I have never QT any fish from my tank and that’s one reason I’m hesitant to buy fish but I recently bought a small tank for QT purposes. I have a heater, power head (small), and some other things to cycle the tank fast. My question is what QT routine should I use. I own polyp lab medic but I hear copper power is a good for precautionary treatment, but I don’t own a copper test kit. My second question is Would it still be wise to use copper power, if not what should I use to treat fish just to be safe even if they don’t show signs of diseases. Or is it even worth it to treat fish that don’t show signs of disease and just monitor them?
