So I made the mistake of not setting up a qt and now 3 of my tangs have ich my scopas and sailfin were fine for months until I added a powder brown and f things up. I will be picking up a 20G today for qt but copper power and copper Hanna checker and 57 watt uv won’t come until Thursday as for now I’ve been adding garlic and ginger to the frozen food during feeding time which it has help in the past but this ich that the powder brown brought is crazyyy…. I’ve looked at some videos on ich treatment and I would like to hear y’all’s 2 cents. Like how long to keep them in copper and HOW OFTEN to do water changes on qt thanks
