Colloidal Silica Problem???
No tests ever showed *reactive* silica in the demin water, but colloidal silica does not show up on such tests. Colloidal silica is notoriously difficult to detect in low (ppb) concentrations, and only a few labs can provide analyses. Even those lab results have poor resolution. The cutoff for detectability at one lab was 100 ppb colloidal silica.
