me thinks you been watching that video of tonys with a car exhaust and 6 inch peace of bike rubber innertube
sounds like a big boy exhaust mod

I did watch that, but it's not where the idea came from ... I've been using a full size sock filter for the purpose since I first started making bio.
I've got three on my system now. One from the processor to the settling tank, on from the drywash tower to the second settling tank and one where my PLUG enters the final storage tank.
Anyhow, I hope the idea is of use to a few people.
