Checker HI784 Ammonia in seawater Mini-photometer HANNA

 

Why measure the ammonia concentration in an aquarium ?

High levels of ammonium indicate disrupted or not yet fully balanced bacterial activity in the filter. Ammonia (NH3) forms from ammonium (NH4) at pH values above 7 and is particularly dangerous. Ammonia levels of 0.02 mg/L are sufficient to cause long-term gill damage. Levels above 0.01 mg/L (ppm) have a negative effect on aquarium inhabitants. It is essential to measure the pH in addition to the NH4 value. The evaluation and assessment of the measured values are done using the table below.

 

Calculation of toxic ammonia (NH3)

To determine the amount of ammonia NH3, multiply the total free ammonia value (NH3/NH4+) displayed by the photometer by the percentage of ammonia indicated in the table below.
