stain out (oxacylic acid) the same as metal out?

I'm trying to get rid of metal stains in my IG pool. I put in 2lbs of Ascorbic Acid into my pool and then I put in "Stain Out". The Stain Out is Oxacylic acid. Is that the same thing as Metal Out? Or does Oxacylic Acid basically do the same thing as Ascorbic Acid so now its like I have a double dose of Ascorbic Acid?

Of course, I ask after I already dumped the stuff in.
