does paraguard leave anything behind in the tank?

that would harm an octopus
i'm looking at buying a used tank for an octo and am told that the tank was treated with paraguard wich i am not fermilar with so i'm wonrering if it will leave a harmfull residue behind like copper based meds will.
if it will can i remove this residue posibly with a solution of muriotic acid or lye since i know these two things can be safely washed away becouse i use them to recharge my di resin
i realy want to buy this tank but it's usless to me if it can't house an octo

A good wipe-down with some vinegar should remove any medications. I'd also be sure to remove any calcium carbonate deposits, since they can bind a lot of copper.
