What kind of Carbon to remove Copper?

[Mini Coop]

I have a blue star leopard wrasse in a 40 gallon QT tank. She has successfully completed her 30 days of copper treatment. I have done 2 50% water changes, but the level is still at .4

I was trying just to remove the copper from the tank but have already gone through 40 gallons of saltwater! UGH! I didn't want to switch her to a brand new tank because they are sensitive and I didn't want to switch her twice and have to get new sand and all of that.

So - - - I have a 75-100 gph hob filter (I think it just an aquion). I have the regular filters with carbon in them, but obviously it isn't enough to make a difference, so what carbon can I use to help remove the rest of the medication?

I still want to do a treatment of prazipro and a 2 week observation

Cuprisorb will absorb the copper faster than carbon.

Cuprisorb or poly filter. I have used both together when I want to remove it quicker, really only need one or the other though.
