SVI flipped from 116 to 84 overnight. Settling like a rock . Bug like looks good. Whats the problem ?
Hi Wadjdanejavel. Couple of questions.
1. How often do you measure SVI (daily, weekly etc)
2. How many chambers in the system.
3. What is the waste water. (Sewage, industrial etc)
4. What sort of aeration do you have (diffused, surface etc)
This information should give a clue as to why the SVI dropped.
