What to do about crystals in my copper forming tank  

+++

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.
