Each area will have its own PFS.
Leslies is one pool company.
SWP is another.
PWP is another...
Pool Filter Sand may also be available in hardware stores.
The key to PFS is that is is screened so all the particles are the same size (usually 30 mesh) so they will not pack together.
Play sand is a mix from dust to fine grit. This blend of sizes can compact in the aquarium, reducing the water movement through the substrate.
There are not a lot of different kinds of sand.
Basically you will have silica sand or limestone sand.
Silica is aquarium safe for hard and soft water fish. It does release silicates, which encourages diatoms.
Limestone based sand is OK in hard water tanks, but will raise the GH, KH, pH and TDS of the tank water if you try it for soft water tanks.
If there are any landscape, rock, masonry or similar stores (bark, soil, rock, stone... in bulk) these places will also carry many types of sand. Some loose, many bagged. Ask. Go out into the yard and see. Maybe there is a broken bag you could see the actual product.
the lub, I just got some top sand (paver sand). Nice color and texture, but I can see the fines. Thanks for the warning. I might just set up a baffle table and turn the hose on for a few hours. Think that will do it?
