Are the wood chips burnt from the top down, using a heat bead? YES
Did the aquarium pump you used provide enough pressure to blow air up through the column of wood chips from the bottom? YES
Do you have a pressure/air flow rating that can be used as a minimum? YES, I used a plug in dimmer switch and plugged the pump into that, and then varied the flow rate with the dimmer switch. This only works for some types of pump
What/how is your reservoir chamber set up? I'll take a photo
How effective is your rig in filtering/cleaning out the creosote and other nasties from the smoke? Objectively, I got a smoother smoke
If you're able to provide photos, that would be great. Incoming
I haven't used this set up since I got the ProQ CSG many years ago, but if I can dig the old rig out I will take some photos.
