Finaplix separating

hey guys, the batch of fina I recently mixed up first turned real cloudy, so I baked it again and then it stayed clear. And now after a couple of days there is a real dark rusty colored settlement at the bottom. If I shake up the bottle the precipitate like substance become suspended in the bottle in tiny bubbles. And idea on what this is? and is it still safe to keep taking it? thanks for the help

wierd. how much ba and how many carts did you use. the solution might be saturated.
