Yup, I've used both. Play sand takes about 30+ times rinsing and then 3 days to settle after you add water, pool filter sand takes 3-5 rinses and an hour to settle.
I have not had a problem with the colored or white playsand clouding, just make sure its synthetic and not actual sand. The natural stuff deffinately clouds the water something terrible!!!
If you do take the play-sand route and have cloudy water- quickest way to decloud it is a premium-paper towel (not one that will break up) around the filter intake...
Change it every three or four hours until it stops collecting sand and then you no longer need to use paper towels. You'll quickly have the cloudyness licked.
i ended up using the filter sand for pools and it has worked out great, i couldnt be more happy, no clouding and when stirred up it settles right back, thanks for the info. also its only two dollars more per fifty pound bag than play sand
