I usually do get foam. My pump has two outlets. I put my castings in a cut off stocking and then put that in a paint strainer bag. I put one 4 inch air stone in that. I use a t connector on the other outlet and attach two four inch stones to each line. Even though I am just using a cheap pump I think the total of 5 stones makes good circulation.

I will have to check out the Earth Juice molasses.
