I'm at a loss if it's truly that high. Maybe batteries of some kind or electronics? No clue tbh and electronics are the only thing I could think of to get it that high. I also know that some plasticizers in storage bins contain lithium but no idea where else it could come from.Reef Crystals and IO Purple are both some of the highest lithium salts I tested and I’ve seen that repeated over many tests now.
However, they are not nearly that high. Usually in the 300s.
That’s either a typo by ATI, testing error, or something is adding it routinely
