i think your pull was too acidic, cuz your water is black, should be gold/red if you titrated right, regardless you nabbed something but a month of it sitting in HCl may leave it weaker than usual, clean w dry tone, wash that w dry ipa, see whats left
btw hardware store hcl is not foodsafe, vinegar however is, and cant hurt you if you eat a lil extra
grow plants, make tea, love life
