What are some good ways to void excess oxygen? Sending it through wooden pipes is rather slow, and I'm hesitant to add Buildcraft just for the void fluid pipe.
I already have BC so I'm just using a void pipe hooked up to a GT pipe fed by a machine controller/pump controlled by a quantum tank's fluid detector.
If you don't have BC I think there's an extra cells block called a fluid void that may do what you're looking for. I think there used to be a TE block called a nullifier too.
Can't think of any way in ic2/GT to do it.
