Flourite as it is is dusty, cloudy enough already, grind it down to sand and your water would probably never clear!
Flourite is made to its size for a reason, to prevent compacting and not be too big for the plant roots to break through it. I am sure even a clay sand would compact. The perfect size gravel or granule for plants is 2 to 3mm which is what Flourite is.
