Why measure ammonia concentration in an aquarium?
High ammonium values indicate disturbed 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 values 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 hosts. It is essential to measure the pH in addition to the NH4 value. The evaluation and assessment of the measured values is done using the table below.
Calculation of toxic ammonia (NH3)
To determine the amount of ammonia NH3, multiply the value of total free ammonia (NH3/NH4+) displayed by the photometer by the percentage of ammonia indicated in the table below.
Example: pH 8.0, temperature: 24°C, NH3 / NH4+ 1.00 mg/L (ppm)
Concentration of toxic ammonia: 1.00 mg/L (ppm) x (5.0 ÷ 100)= 0.05 mg/L (ppm)
Percentage of ammonia (NH3)
| pH | 21 °C | 24 °C | 26 °C | 29 °C |
| 7,6 | 1,7 | 2,1 | 2,4 | 2,9 |
| 7,8 | 2,6 | 3,2 | 3,7 | 4,5 |
| 8,0 | 4,1 | 5,0 | 5,8 | 7,0 |
| 8,2 | 6,3 | 7,7 | 8,8 | 11 |
| 8,4 | 9,7 | 12 | 13 | 16 |
| 8,6 | 15 | 17 | 20 | 23 |
| 8,8 | 21 | 25 | 28 | 32 |
