I'm looking for a new transparent kalkwasser container so I know when I'm out and to be sure I don't dose the slurry. I have seen these brew vessels that look really nice. I think they are made of Polyethylene terephthalate PET I was wondering if they can resist a solution of fully saturated kalk. Does anyone know? And how many day's wil kalk stay fully saturated in a closed of container like this? Thanks for all the help!
