Thanks for the reply,
My tangs were being treated with cupurmine I got to 0.25 and they started acting funny darting,shaking ect.... I checked everything,all seemed well. I was still concerned so finally I got a response from someone saying that cupurmine could not be used with a declorinator! < I did not no this ,It's not stated on the bottle!
and this is what I add to my water because I use well water so declorinator,with cupurmine caused my safe dose of copper to become toxic!
This is why they were shaking ,darting, ect....
I had to do a 100% water change with no declorinator and they have since been in with no copper recovering.
Both tangs are back to normal and I dont think I will take a chance of even adding a med if this is what happens when you add a simple declorinator
So Im going to let this thread die because I will not be adding both meds together but thanks everyone for your help!
