It is more the depth and lack availabile free O2
that will have anything to do with hydrogen sulphide. It is a byproduct of anaerobic bacteria as they consume obligate O2
soucres. Anoxic bacteria IMO
, are more prefered than anaerobic unless in a controlled environment such as a seperate fuge or coil de-nitrator.
