Mike--I realized I gave some bad, or at least incomplete, advice--when you stand jars of water to determine whether you have clay in suspension, you need to add some alum, available at drugstores, to the water in one of the jars to see if it clarifies at a different rate than the other. If it does, you have suspension and could benefit from aluminum sulfate. I'm sorry, and I hope you're making progress on your various battle fronts!!
