I am setting up my Rena XP3 tonite and was wondering if i should hook my external CO2 reactor up on the intake into the filter or the outtake from the filter? I was thinking the outtake would be better b/c every couple months i have to clean my reactor to rid it of the build up on the bio balls. Currently i am running it with a powerhead as a pump.
TIA,
Jimmy
