@icedquinn the first time i ran that citric acid through my machine it only had a few floaty white things in the output, but i got the bright idea to blow into the outlet tube like a child making milk bubbles and what came out can only be described as a calcium slurry. I guess they're just that sensitive.
But this has to be "solved" for the commercial machines because i sincerely doubt every Sonic has an on-site distiller. Probably the cheap ones have aluminum chambers or something
