So this is how I run my qt which is based off of humblefish procedure with a few minor changes. My fish go through 30 days of copper power. I usually start them off at 1.0 ppm and ramp up over a few days unless it is a wrasse or anthias in which case it is 7 days. The first 14 days they are fed frozen that is soaked in seachem focus, vitachem, metroplex, kanaplex, and furan 2. It is much more effective to feed antibiotics than just dosing into the water column. Many times new fish come in with parasites and the injuries caused by them can turn into bacterial infections pretty quick. This of course is only effective if the fish eats the food but its normally not an issue. Day 24 the first dose of general cure is administered and then again on day 29 for flukes. Lmk if you need any help. I am a strong advocate for fish qt and I think you'll find success with fish will dramatically increase after qt!
