Just wanted to mention that Celticloud was quoting 2 lbs / cubic foot, which is about 1 lb / 4 gallons.

badflash seems to have misread this as 2 lbs / cubic foot and so thought the recommendation was too dense and so instead suggested 1 lb / 2 gallons which is twice as dense as Celticloud had recommended.

Sorry I know this is an old post, but its coming up on google searches and I wanted to clear this confusion up
