I found at my pet store an adjustable stone. This is made up of several plastic sections that screw together. The tighter you twist them the more bubbles. They shouldn't fall apart like the stones you guys are describing.

I ve been using this for a couple of weeks now.  My only question is that the water is staying clear but I am still getting that white build up on the outside of the bucket.  The stuff feels like crisco so i am sure it is grease but should'nt the water get cloudy if it is still pulling grease out?

I have an idea not sure how well it would work but..since fish tank heaters and air stones are being used why not make it complete with a fish tank filter set up. wouldnt that filter the grease out?? not sure but i think it might...

im sure the filter would have to be changed out alot but once theres no more grease on the filter then your done degreasing?? just a thought..

The Foam and grease would plug up the works IMO
