Nitrite lock occurs when the ammonia (NH₄) doesn’t complete the full nitrification process, which typically involves the following steps: Ammonia Oxidation (NH₄ → NO₂): Ammonia is oxidized to nitrite by ammonia-oxidizing bacteria (AOB). Nitrite Oxidation (NO₂ →...

Dissolved Oxygen Uptake Rate (DOUR) and Specific Oxygen Uptake Rate (SOUR) are often used to monitor biological system health on a daily basis. When used frequently, oxygen uptake rates show changes in bacteria growth/respiration rates. I have included the protocol...
