3 questions for you:
- what is the flowrate recommended?
- what is the high nitrate removal rate you have achieved and what is the typical nitrate removal rate for a setup?
- is deniball a must? or just good to have? Does it help to performance better?
Thank.

1. The flowrate is very slow as compare to nitrification level. There are no specific flowrate as it depends on too many factors. Some examples: size, amount of anaerobe, qty of carbon source, pH level, temp.....etc.
2. For my NR1000, I have managed to achieve a flowrate of 20 l/hr with some modification. It is didn't last for long though. Within 1 week of operation, nitrate was detected at output and followed by clogging.
As to your question on typical removal for a setup, I would it depends largely with respect to your bio-load and what is the reasonable level of nitrate you would want it to be.
3. Deniball is not a must. It is just convenient and provides constant supply of carbon source.
