I have playsand in all my tanks, have for many years now. I know people always say how dirty it is but I have never seen it any worse than any other sand IMO. At least the ones I buy from Lowes that is. I don't even bother pre washing it and my tanks are always clear within hours of adding sand.
While I have had an impeller or two go down it's usually just because I had the intake too close to the substrate. Now a days I run my intakes about 6" off the substrate and that seems to be enough to keep any sand from getting kicked up into them.
