Hi I have a few questions.. you said you use Prime, at what point do you use prime in this setup? After a fresh water dip if you see a stringy poo on a fish do you treat with prazipro? if yes then you use 2 doses in 14 days right? so after you use carbon you dose copper for 14 days.. If you need to treat for something else after, how do you remove the copper from the water? carbon again and 50% water change?
