I've been using a cellulose based DE replacement for a while. It too makes a bunch of dust, so care is required. I believe it is less of a concern as it does not contain small silica particles like DE. I find it does an excellent job of polishing the water. I noticed the water in our pool getting a bit cloudy this weekend (ducks have been swimming in the pool as they always do during the beginning of spring). I noticed the pressure on the filter getting on the high side, so I simply backwashed for a couple of minutes and added more of the cellulose filter media. After running the filter on its normal schedule, the water is now perfectly clear and looks great. BTW, I just add about 8 cups of this directly into the skimmer (basket removed), and then check the filter PSI. With no media, this is about 15 PSI, but when the correct amount is added, it is 20 PSI at around 2700 RPM on the IntelliFlo. When it reaches about 25 PSI, I know it's time to backwash. So far, this has worked well.
