I have crystals in my copper forming tank. I have removed them . I
refilled the tank before I realized they were there. I want to Know:
Do I have to replace any copper sulfate, brightener, or sulfuric
acid. Is it safe to turn the tank on as it is. Any other information
that I need in this situation.
