what ammonia level is safe
Table of contents
[MISSING: System.API.no-headers]Ammonia toxicity changes for different organisms but one thing is constant and that the desired level is as close to zero as is possible. Marine organisms and fish tend to be more sensitive and where as fish that have evolved to live in ponds or puddles such as carp or paridise fish tend to be less so.
As a rule of thumb and if measured directly we use the following chart.
| NH3 level | PPM (mg/L) | PPM (mg/L) |
| safe | 0.000 | 0.020 |
| alert | 0.020 | 0.050 |
| alarm | 0.050 | 0.200 |
| toxic | 0.200 | 0.500 |
| deadly | 0.500+ |
NH3 is reported in the unit of ppm but this is interchangble with mg/L as it is a gas disolved in water.
