Kordon copper aid

[Bdog4u2]

Has anyone had any luck with copper aid from kordon. I have a powder brown tang in quarantine and seems to be showing signs of velvet. I bought it from petco it was fat and colorful and had only been in their system for a few hours. It's still eating good and I have this on hand

i've never used copper aid though it's a chelated copper so it's therapeutic level is 1.5 -2 and the api copper test kit is what you need for it. Good luck!
