How to hold down Copper Levels in Ebonol C-Special Bath

We are currently using an Ebonol C bath to oxidize copper for bonding purposes. We are having issues maintaining the Copper content in the bath. Is there a specific chemical (i.e., Cuprous sulphate) that we would be able to add to the bath to keep the levels where we want them?

Have you tried contacting Enthone, the manufacturer (they may also be listed as Cookson Electronics)
