CB1 'contankerous' was the first adjective that came to mind for some of your historical 'debateful' comments on the forum. We should take no offense or defense. I am now reading PMs on a regular basis so you can use that as communication. I still want to know what you think leaves the hydrated pellet as it is squeezed to make it more dense. Something has to happen internally during compaction to allow it to sink. On close examination, sinking pellets are quite dense compared to floating pellets. I think the pressure used during pellet extrusion makes a difference in how much air is in the pellet. From Wikipedia: Adjusting parameters such as temperature and pressure enables the manufacturers to make pellets that suit different fish farming methods, for example feeds that float or sink slowly and feeds suited to recirculation systems."
