RS - My theory is you want to leave the alum-treated clay particles on the bottom as a coating over un-treated clay. Playing around with 5 gallon bucketfuls of pond water showed me the clay settling to the bottom is quite significant - perhaps it would amount to several inches in 5+ feet of pond water column. You can re-stir the bucket and it will turn cloudy, but re-settle again quickly when left alone. Having a layer of the treated clay may help cut down on the amount of un-treated clay stirred up by critters. Just a thought.
