Ammonia | Xylem Analytics

Ammonium (NH4+) — or its uncharged form ammonia (NH3) — is a form of nitrogen which aquatic plants can absorb and incorporate into proteins, amino acids, and other molecules. High concentrations of ammonium can enhance the growth of algae and aquatic plants. Bacteria can also convert high ammonium to nitrate (NO3-) in the process of nitrification, which lowers dissolved oxygen. Ammonia in ...

Ammonia/pH Aqua Sensor – Pacific Sentry

With initial use, wait 15 minutes for the NH3 sensor to hydrate and up to 24 hours for the pH sensor to hydrate before making first reading. Thereafter they respond quickly (1-5 minutes) to changes in NH3 and pH. “This sensor can show the presence of ammonia when other tests can’t.” Match the sensors to the respective color-gradient indicator charts to readout the ammonia & pH ...

Ammonium und Ammoniak im Aquarium: Ursachen & Maßnahmen

Neben einem NH4/NH3 Verbundstest sollte der pH-Wert gemessen werden. Damit lässt sich herausfinden, bei wie viel Prozent es sich bei dem NH4/NH3 Gesamtgehalt tatsächlich um Ammoniak handelt. Ab wann ist NH4/NH3 zu hoch? Bei zu hohen Ammoniakwerten können Fische an einer Ammoniakvergiftung sterben. Ein zu hoher Ammoniumgehalt kann hingegen ein Algenproblem verursachen. In einem intakten Aquarium sollten NH4 und NH3
