My permanent QT tank is finally cycled so I am going to starting the TTM soon. I have around 12 fish that need to go through it, ideally I would want to do all the fish at once but that's definitely not happening sine I am using two 10 gallon tanks. I have prime on hand for ammonia control as well. What are some ideas about a magic number for me to go with to get these fish done? My original was going to be six but like I said I want to keep the ammonia under control, so I came here to get some insight.
