For the feed rate, we agreed to maintain the 120 L/hr at the moment. If we see occasional (less than 1 day per week) DO values under 1.5 mg/L, we will leave the flow rate at 120 L/hr even when DO becomes low. If we observe the DO is below 1.5 frequently (more than 1 day per week), we will select a new lower feed rate. In either case, we will run a consistent feed rate all the time and will not continually adjust to manage DO.
