If I had to choose playsand or Pool Filter Sand, I would choose the Pool Filter Sand. The Playsand looks natural, but is crazy hard to clean. And when you do water changes and syphon waste off the bottom of the tank, it's very hard to tell what is waste and what is sand with Playsand. PFS is easier to see where waste and food debris are. And I happen to love the white look, maybe that's just me. Plus, you can pretty much dump it right in the tank (after turening filters off, obviously) and it won't cloud at all.
