Lost Tang during Copper Ich Treatment

[Tw1]

So I have been treating Ich on my Yellow Tang, Kole Tang and clowns since Thursday (making today day 5).

I came home from work tonight to find my tang upside down on the bottom motionless ;Dead The yellow tang had shown white spot on the pectoral fins last weekend.

What did I do wrong?

Temp- 28oC - a little high I admit. Have turned temp down now!
PH - 8.1
Amonia - 0
Nitrate - 10
Nitrite - 0
Copper 0.5

I’m using NB labs anti parasite treatment.

I’ve got a powerhead in there pointing at the surface. It’s a 120L tank with 100L in it.

What copper treatment brand are you using that has to be at .5 ?

I’m using NB labs anti parasite treatment.

^^ Need more information about this copper product, as I am unfamiliar with it.

Is it chelated or ionic copper? Or possibly copper sulfate?? What test kit are you using?

I don't know that it's an oxygen issue. But it is recommended to use an Airstone as well. I feel like more is better. Fish are already going through alot of stress with the parasites, and then the heavy meds. So if you can make the breathing part easier the better off you are. Keep in mind the parasites do affect the gills heavily. Good luck, hopefully now that humble has your copper ingredients he will have additional insight as well

I wouldn’t personally mix formaldehyde and copper, never heard of that product either!

 

[Humblefish]

You actually can mix formaldehyde and Copper(II) sulfate, but it's very harsh on certain fish.

@Tw1 I suggest using one of the copper products mentioned here for treating ich: https://www.reef2reef.com/threads/copper-treatment.193343/

I'm not sure about chelated copper, but you can get Cupramine in the UK: http://www.swelluk.com/seachem-cupramine/
