It would seem "most" rebreather allow the user some way of "crushing" in extra slime but on the SK you fill it and thats about it...
I give it a few good whacks to settle it down and refill the space 2-3times until I am level with the pod holes but you can't really "pack it down" like all the others I've seen.... I just pack it till it barely rattles when you shake it... very scientific!
