PM RFCa4 reactor

[dawen]

can u only fill half the reactor chamber with 8lb media instead of 15lbs in the rfca6 with half the chamber empty if the tank its not high demand? will that also effect the ph?

I've been using a reactor for 3 years and I honestly dont know how to answer that. I guess its because I'm a carpenter and not a chemist.

However here is an article that might help you answer it yourself.
