Question: When rejuvenating acidperoxid adding HCl and air from the pump to the aquarium for free O2.Da you constantly use the pump or just until a emerald green color?

If possible, keep the air running through the solution even after the base metal is dissolved. This will help oxidize the tin chloride into tin oxide powder. After the base metal has been consumed, continue the air for another day after removing foils and solids. After that time, remove the air and cover loosely.

There are several posts on this but here is one that help you understand why tin is not your friend.
