Copper treatment with Cupramine, How do I re-dose with water changes? :O

[Coralgurl]

I've used copper and dosed the new salt water, and retested after adding to the tank. Once you are at full dose, you can/should keep it there.

Curious why you are using copper treatment? Its very hard on the fish and a slight overdose can kill them. You also need to closely watch your PH with copper.
