Just re reading the Pentair information on the clearPro, They state "Traditional sand filters can only remove particles in the 50-100 micron range"
Well that is not really true, depending on the grade of sand used, it is pretty widely accepted that sand filters filter to around 15-25 microns.
So if according to their marketing information they can "removes particles up to five times smaller..."
Then they are polishing the water to 10-20 microns, not really much different to a good sand filter without ClearPro, or have I mis understood?
