Nitrite in the outlet of the filter:
If the outlet of the filter contains high amounts of nitrite,
the feeding rate is too low. Increase the feeding or lower the flow rate. In most of those cases,
the redox potential is too high (more than -50 mV).
-
Nitrate in the outlet of the filter:
High residual concentrations of nitrate often occur together
with high nitrite values.
Caution!
Most nitrate tests are disturbed by high nitrite concentrations!
In this case, the redox potential is also too high. Increase feeding rates, decrease the flow rate.
-
Hydrogensulfide in the outlet of the filter:
The filter smells like fouling eggs. In most cases,
the redox potential is too low (below -300 mV). Reduce the feeding, check the flow rate and
increase it if necessary.
