Yes you can use white playsand... you can use purple play sand if you wanted (crayola brand is safe anyway).
First week or so, no matter how well you rinse the sand you'll have cloudy water and floating particles... it will eventually go away.
Pool Filter sand costs slightly more and doesn't cloud the water.[/QUOTE]
That is my next experiment.. I love my Tahitian Moon but the filter sand looks interesting and says it is uniformly smooth. Want to see just how well it stays on the bottom... The moon sand is gonna be hard to beat.
