If you find a pool sales place or pool supply store you can pick up 50lb bags of pool filter sand for I believe 15-20$ is what I was getting my at. 1 50lb bag was enough for my 100g when I set it up.
Where I live they're like 4.20$ for a 50lb bag at Lowe's or Home Depot.
I love how people say "PFS is better than playsand." There are so many different kinds and grain sizes of each out there.
Because it is.... Of course there are different granule sizes but the standard PFS you would buy at a hardware store or pool store is pretty universal in size and consistency just as common Play Sand at a hardware store is universal in size and consistency for the most part unless you go looking for a particular uncommon grain size, and if that's the case you might as well be buying the fancy caribbean sand or stuff designed for an aquarium that's like 20$ a bag. I can tell you every Home Depot, or Lowe's I've been to doesn't have a "choose your granule size!" for Play Sand... Just the one 50lb bag.
