Hi all, first just wanted to thank you all on this wonderful forum for the advice and knowledge so far, my first attempt at quarantining is going very well even with a tank full of ich 
So I had a thought regarding ich and copper. I understand that copper is ineffective until a minimum therapeutic dose is reached. I’m using Copper Power.
I have 5 fish in QT right now - lyretail anthias, linespot flasher wrasse, longfin fairy wrasse, royal gramma, bicolor blenny. The two wrasses had ich within 24 hrs of introducing them to QT. A few days later the blenny started flashing and the anthias had a few spots. Both wrasses came from one LFS and the other 3 came from another.
After starting copper both wrasses seemed to perk up and act more lively. This was around the 0.5-1.0ppm range. After just a few days, I cannot see any spots on any of the fish and I’m still not at the therapeutic dose, mainly because I don’t trust my ability to read my API copper test and my Hanna checker will be here Friday. All fish are happy and comfortable and eating well.
I read that some LFS keep a low dose of copper in the water to mask symptoms of ich. Based on how these fish reacted and onset of ich I think that may be true. But how exactly does that work? It’s my understanding that copper doesn’t kill those attached to the fish right away. Like I said, fish had visible ich and now they do not within just about 3 days and only at about 1-1.5ppm. How exactly does a low dose of copper keep visible ich off the fish? And I assume if I were to move the fish to the DT with no copper present, ich would resurface? Very confused on how this works. Thank you in advance for any help!
