What Does a TDS Meter Actually Detect?
Since TDS meters are often used to test water "purity," it is important to understand what they do not detect. As conductivity meters in disguise, TDS meters will only detect mobile charged ions. They will not detect any neutral (uncharged) compounds. Such compounds include sugar, alcohol, many organics (including many pesticides and their residues), and unionized forms of silica, ammonia, and carbon dioxide. These meters also do not detect macroscopic particulates, as those are too large to move in the electric fields applied. So if you see "rusty" looking water from iron oxide particulates, that won't be measured. Neither will anything else that makes the water look cloudy. Bacteria and viruses also won't be detected.

Eccoti spiegato l'arcano. In parte.
Mi verrebbe da dirti che viene dall'acqua di rubinetto, ma non ci sta col fatto che ora non la trovi. prova a testare l'ammoniaca sull'acqua di osmosi che produci.
L'alternativa è che venga dal sale...
Detto questo in 10 giorni avresti dovuto vedere sparire l'ammoniaca... luce non ne dai ancora?
