Hab zuerst gedacht ich bin zu dumm das richtig zu bedienen aber nach genauer Beachtung der Bedienungsanleitung hat mir das Gerät einen Extrem überhöhten Clorgehalt angezeigt. Dachte dann auch: Ok zu viel Chlor im Wasser aber bevor ich was unternehme prüfe ich nochmal anderst. Hab dann frisches Leitungswasser getestet und ebenfalls ein zu hohen Chlorwert erreicht.
