No.
The pattern of flow that comes out leaves regions similar in shape to egg
crates that are unaffected by the RFUG., so called "dead spots".
The other issue is with the poroisty of the gravel etc, if it has high
surface area etc, then it possesses lots of internal anaerobic zones that
can help reduce iron.

Thanks Tom, I didn't even consider the internal pores of the gravel or the "dead spots". You have been a great help.
