Hydrofluoric acid was accidentally added to Nickel Strike tank

Hi, this is the case: Addition of 1 gal of Hydrofluoric Acid instead of Hydrochloric Acid in the nickel Strike tank. With a capacity of 192 gal. How can this affect my bath. Thanks, I appreciate any suggestion.

Hi, Edecio

Sorry, but the tank must be dumped because you will not be able to precipitate the fluoride out of it. It may be possible to plate out a significant portion of the nickel as scrap metal first though. It's an expensive mistake, but such a dangerous one that the lesson learned might be worth it :-(
