good subject on checking on equipment. I never did the bubble bag process and have done the Gumby method several times.
Now I do a modified Gumby method with five gallon ez strainers. they fit on top of a five gal pail and come in different microns, I always save the water and do the Gumby last step, let it settle to the bottom, remove most of the water, and the rest is in the pipe..smoking.
hope this has not already been posted, as I still have a lot of reading to do.. lol
